Unidentified Crab -- 2/23/10
Hello again!
<Hello Frank, Lynn here today.>
I was wondering if you all could help me tell what kind of crab I got here. My buddy at the LFS gave him to me after I spotted him in their live rock tank where it must have hitched a ride. It looks VERY similar to an emerald crab.
<Does it have the same flattened/scooped claw tips (as opposed to pointed)?>
It has the hairy legs but it is a reddish brown color. I've been looking at some pics of different species (strawberry crab, ruby crab, and others) but I'm just not sure if I should add him to my tank with my corals and mandarin.
<Personally, I wouldn't, but it's up to you. Crabs are opportunistic omnivores and scavengers that pose an increasing risk to livestock as they increase in size. A hungry crab will eat whatever it can grab. Keeping the crab well fed with sinking pellets or meaty bits of marine origin can help deter unwanted predation, but there are no guarantees.>
I'm attaching pics so I hope they come through. Let me know what you think.
<Unfortunately, I can't see enough detail in the photos to be of much help. The general carapace shape and striped legs do appear to resemble Mithraculus/Mithrax forceps (aka the Red-Ridged Clinging Crab), but I could be way off. Please see the following links for comparison/more information:
http://www.dnr.sc.gov/marine/sertc/images/photo%20gallery/Mithraculus_forceps_S806.jpg
http://www.wetwebmedia.com/Arthropoda/CrustaceanPIX/SWCrabs/Crab%20IDs/SWCrabs2.htm
One thing I'd like to point out is that even if this is a Mithraculus/Mithrax crab, it still presents a potential risk to livestock. What has me more concerned is the possibility that this crab could be something else entirely. It could be a species that grows in size and aggression fairly quickly. That could be a big problem, and believe me, trapping an entrenched crab can be quite a challenge. It's a shame really. Crabs are such neat little creatures. Unfortunately, they just can't be trusted long-term around other livestock.>
..and thanks again for all your hard work.
<You're most welcome. Good luck with the crab!>

Crab Identification: Porcellanid -- 2/23/10
Hello WWM crew,
<Hello Adam, Lynn here today.>
I have a question about a crab I recently found in my reef tank.
<Fire away>
I noticed someone else asking about what I think may be a similar crab on 1/24/10. That post noted Porcellanid but I have searched and not found anything that resembles this crab.
<Unfortunately, you may not be able to. There are many species, not all of which are available as photos on the web or within readily available books. Beyond that, there are species that haven't yet been formally described. For example, your little fellow could be locally known as 'Bob's crab' in some corner of the tropics, but until it's studied, described, and presented to the rest of the world, the chances of us running across any information/photos range somewhere between slim and none. It's frustrating, I know, but for our purposes, it's often enough to know which family the crab in question belongs within.>
Unfortunately I do not have a picture as it is the smallest crab I personally have ever seen. Perhaps 1/2 cm across.
<It could be a juvenile or simply one of the smaller species. Typically, these crabs are fairly small, with carapaces no larger than 1/2" across.>
It is a tan color but instead of claws it has 2 filter fans.
<Yep, you've got a Porcelain crab, aka a "false" crab ("Anomuran") in the family Porcellanidae. These crabs have 3 pairs of walking legs (as opposed to 4 in "true"/"Brachyuran" crabs), two claws (usually large, used mostly for territorial disputes but can be quickly shed when crab feels threatened), one significantly smaller pair of legs used for grooming that are held up against the abdomen or posterior end of carapace, two long antennae just behind the eyes, and two specially adapted fan-shaped mouthparts used to filter organic particles/plankton out of the water. As for the missing claws in your individual, they could have been dropped due to a perceived threat/stress, or lost due to injury/predation.>
They look just like feather dusters but are clear. It sits in the same spot all the time and I only see it at night with the flashlight. It just sits there and filters away with these fans. Opening and closing them in the current.
<Terrific observations! This behavior is typical of Porcellanids. Thankfully, they're filter feeders and scavengers that don't normally pose too much risk in a mixed reef system. I would offer it the occasional sinking pellet or meaty bit (of marine origin) such as shrimp, clam, silverside, or Mysis to supplement its diet. Unless you have a fully mature reef system, the crab may not be able to acquire sufficient food from the water column alone. For more information, please use our Google search engine and the terms Porcellanid or Porcelain crab: http://www.wetwebmedia.com/Googlesearch.htm >
Any insight would be greatly appreciated!
<Hopefully the above information/Google search results will help. If not, please don't hesitate to contact me/us. In the meantime, enjoy your little Porcelain crab!>

Another 'Crab ID': Must Be Porcelain Crab Season! 3/2/10
Hello WWM Crew!!!!
<Hello Sandra, Lynn here with you today!>
This little guy fell out of a piece of live rock I was moving out of my fish only tank.
<Wheeee!>
I'm going to put him in my refugium as I know there are no truly reef safe crabs except for the commensal crabs in SPS corals.
<They're one of the safer groups anyway. They're generally small and stay within/around their particular coral, feeding on coral mucus, a bit of tissue and whatever else they can find.>
I have several of those and wouldn't dream of removing one.
<Good, I'd leave and enjoy them.>
He appears to be a filter feeder maybe in the Porcelain Crab family,
<You hit the nail on the head. It's a classic Porcellanid (family Porcellanidae) showing the distinctive 3 pairs of walking legs, two large claws and long antennae just behind the eyes. If you look closely, towards the back of the carapace on either side you'll see another small pair of legs folded up and held against the body. These are used for grooming. Up front, you can see the large mouth parts that open up into the distinctive fan-like structures used to filter organic particulate matter and plankton from the water column. All in all, it's a neat little crab.>
..but, of course, I couldn't find a picture that looks exactly like this guy.
<That's understandable. There are many, many, crab species out there. Knowing where the crab originated would help, but even then, it can be a considerable challenge. Sometimes you get lucky with a very common, well-known species, but most of the time narrowing the ID to family level is about as good as it gets.>
I have 2 in my 300 gallon SPS tank that don't appear to be bothering anything in their vicinity so I wanted to ask while I happened to have this one out what kind he is
<Unfortunately, a Porcellanid is about as far as I can take this ID without having the little crab in front of me to see all the pertinent/distinguishing details.>
..and could get a decent picture of him. If I need to get out the trap then I will.
<Well, if you want to keep that particular tank a fish-only, I'd move the crab to the 300g display. Porcellanids are generally small and don't have much negative impact on a reef system. They do scavenge as well as filter feed though, so I'd recommend offering it the occasional pellet food or meaty bits (of marine origin). Sometimes these crabs aren't able to obtain enough food from filter-feeding alone.>
The pictures don't show the color as well as I would have liked but he does have some red and blue accents.
<Yes, they show up fairly well after enlarging the photos. It's actually a very pretty little crab.>
I didn't know I even had this one until I took the rock out of the water and he fell out. The ones in my 300 I've only seen at night and they are actively moving their antennae and look like they are filter feeding.
<Typical behavior>
I haven't seen them picking anything off the rocks. I have 6 separate refugiums I could put him in. 3 with a DSB, rubble and Chaeto. 2 with larger and smaller pieces of rubble and Chaeto. And 1 with just rubble and Chaeto. Which refugium should I put him in to give him the best environment? I want him to have the right home.
<Hmmm, I'd either put him in the 300g display as mentioned above, or put him in one of the fuges with a DSB. You might want to add a couple of larger rubble pieces though so he'll have a place to hide. Crabs and other crustaceans like to hole-up in a secure spot when they molt as they're particularly vulnerable until their shell hardens. One other issue with the fuge relates to the Chaeto. Just make sure there's enough room at the bottom for the crab to crawl around. I've seen Chaeto take off to the point where it's packed top to bottom. For more information on Porcelain crabs, please see WWM, starting with the FAQ's at this link: http://www.wetwebmedia.com/SWCrabIDF15.htm >
Thank you all so much for the volumes of information and advice over the years.
<On behalf of Bob and the crew, you're very welcome.>
The changes you have made to the site to make information easier to find in the last year is awesome. Maybe 1 day you could add an image search feature similar to google image search so you could scan through "hitchhiker crabs" images and click on the picture to go directly to the referenced page. That would be really, REALLY awesome.
<That's a great idea!>
Thank you,
<You're very welcome.>

<Hello Randy, Lynn here today.>
I have a large guest that snuck in on some live rock.
<Surprise!>
I have been chasing this guy for a month and finally caught him.
<Ah, success at last!>
Not sure what kind of crab it is or if it is reef safe.
<It depends on what you mean by reef safe, but all in all, you did the right thing in removing it.>
I noticed shells lying around the rocks he was staying under, but I don't know if the shells were occupied before he got them.
<Unless the empty shells were there before the crab moved in, or you've got a Mantis shrimp somewhere in the vicinity, I'd say he probably ate them. Crabs like this tend to prey on bivalves, snails, sessile invertebrates, worms, other crustaceans, etc., as well as scavenge. All in all, they're opportunists that will eat whatever they can get their claws on.>
The rock came from a 220 gal reef tank with 400 Lb of rock. I happened to get him in rock from that tank. Can anyone ID him for sure?
<I can tell you that it's something in the family Xanthidae. That's about the best I can do without having the crab right in front of me. Even then, I'd be doing well to narrow it to genus level. There are just so very many genera and species within this large family that trying to take it further with a single photo is pretty much impossible - for me, anyway!>
Fish stores around here keep telling me different things, from a fiddler
<Negatory>
..to a strawberry crab.
<I guess it depends on what they call a strawberry crab, but what you have is not one of those usually associated with this name.>
He is 3 in wide, 1.5 in front to back, when he spreads his claws, about 6 in tip to tip.
<Holy guacamole, he must have been hiding in the equivalent of the cavernous 'bat cave' within those rocks!>
Hope to put him in my refugium.
<You could, but it would no longer be a refuge for the other beneficial critters within. I'd consider putting it in a tank of its own, or finding it another home altogether. These crabs are neat little creatures but can be very destructive. Further compounding the issue is that as their size grows so does their appetite.>

Unidentified Marine Crab - 2/2/10
Hello WWM,
<Hello Mark, Lynn here this evening.>
I found an unidentified crab in my reef tank and wonder if you know what crab it is
<I'm sorry, but I can't see enough pertinent details to be sure.>
..and whether or not I should leave it in the tank?
<It's probably fine right now because it's so small, but as with any other crab, risk increases with size, opportunity, and competition/lack of sufficient food.>
I've observed it briefly; it seems to pick the rocks for algae. I've attached a photo for your convenience. Any information you can provide or point me to would be greatly appreciated.
<Well, crabs are neat little creatures, but I don't trust any of them. Even those that seem to be primarily herbivorous can and will eat just about anything if they get hungry enough and the opportunity comes along. Basically, you've got a couple of choices. Either trap/remove the crab now and find it a new home in the sump or elsewhere, or let it hang out for awhile and keep a sharp eye on things. If you do choose to let it remain, be sure to keep it well fed with meaty bits (of marine origin), or sinking pellets. Please see WWM for more information, starting here: http://www.wetwebmedia.com/swcrabcomp.htm >
Thank you.

ID Crab: Porcellanid -- 1/27/10
Hi Crew,
<Hello there, Lynn here this evening.>
Is this a porcelain crab?
<It certainly is. It appears to be Petrolisthes galathinus, or at least one of the species within this complex. Common names include the Purple Porcelain crab and Banded Porcelain crab (family: Porcellanidae). They're primarily filter feeders, but will scavenge as well. Bob has also noted that they're not to be trusted around other invertebrates so beware if you have any. See this link re: http://www.wetwebmedia.com/galatheids.htm >
I don't keep crabs not even hermits because I have a small tank with small fish.
<That's understandable. Fortunately, these shy, mostly nocturnal crabs stay fairly small (carapace width to ~1/2"). Those big claws are mainly for territorial squabbles and are sometimes shed if/when the animal feels threatened. See this link for a photo of P. galathinus feeding. http://www.animal-image.com/CoralReef/Crabs/Banded%20Porcelain%20Crab/slides/BandedPorcelainCrab_PetrolisthesGalathinusTRCr_Ap8R.php >
Got this by mistake in an order. Keep it or not?
<It's up to you. While these crabs pose less threat than say, a big Xanthid, they're still scavengers. I just can't tell you for certain that it won't go after sleeping fishes if it gets hungry enough or the opportunity presents itself. One way to lessen those chances further is to keep the crab well fed with meaty bits (of marine origin), sinking pellets, etc. Honestly, I think it's a neat little crab. As long as I didn't have a tank full of tiny fishes (gobies and the like) I'd be tempted to give it a chance. Take care and good luck, LynnZ>

Crab Identification, no pic! 1/24/10
Sorry to bother you for some help on a crab identification. I have been looking online for hours (trying to help someone with an ID). I came across this crab once and can't remember for the life of me what is was. I do not
have a picture, but here is the description.
About 1.5" and white. It does not have any claws, but in their place, filter feeding fans (not to be confused with the anemones on the boxer or pom pom).
Thanks for your help.
Bret Yaworski
<Mmm, freshwater? Maybe summat of the genus Attya (shrimp) or in this family... Marine? Poss. a Porcellanid family member... whose claws are often obscured, mouthparts are of filter feeders. Bob Fenner>

Crab ID 1/4/2010
Hello Crew.
<Erik>
I am in the process of trying to catch some of the crabs in my Red Sea reef tank. Most all need to go. I have already caught one shamefaced crab.
There is at least one more of these. I have attached a picture of one crab that may be ok to keep. I believe it to be a Black Mithrax. Note in the picture the round plates at the end of the pinchers. He feeds heavily on algae, but obviously will consume meat as a small piece of shrimp was used as the bait. Should he stay or go?
<Mmm, please see Lynn's input on our forum, here:
http://74.125.155.132/search?q=cache:ZjLAMxocUDcJ:bb.wetwebmedia.com/viewtop
ic.php%3Ff%3D25%26t%3D189+black+mithrax&cd=1&hl=en&ct=clnk&gl=us
Also, many of the other crabs are very small and I have not had luck
catching them in the traps. Only the larger crabs get caught. Is this normal?
<Not atypical, no>
I am using a small canning jar tilted against the rock with a small piece of shrimp in the bottom. Is there a better trap for smaller crabs?
<Whatever works... the small, all-plastic rodent traps (or repackaged/labeled ones for aquarium use) from Home Depot, Lowe's et all... are my faves... have a dropping un-openable (by them) trap door... aka "Have-A-Heart" traps for terrestrial use>
Thanks again for all the great information. I am certain I would not be having the success I am having without this site.
Kind Regards,
Erik Hayes

Crab ID 12/7/09
Hello all,
<Misael>
I found and plucked this little crab off of a coral that I believe to be Turbinaria reniformis. I've searched around for an id, but can't find anything and I need to decide soon whether to put it back or not.
<Interesting... can you send larger, more-resolved images? This looks to be a Pinnotherid to me... that usually live w/in the mantle spaces of bivalves>
I'd love to keep it, but don't want to put it back in if it's harmful. I've had this coral for about 7 months and never noticed any obvious damage to it or any other tank inhabitants.
Thanks!
- Misael
<Do you have any clams? As you've had this animal for so long, and it appears small, I would put it back, keep it. Bob Fenner>

Full size pix

Re: Crab ID -- 12/08/09
Hi Bob,
<Misael>
Thanks for your quick response. I put it back in tank and it eventually crawled into a little hole in the middle of the coral that I never paid attention to before. Unfortunately, I didn't get any more pictures of it before putting it back and it's not really visible at the moment. I attached the same two pictures but at maximum resolution in case that's
helpful.
<It is... to an extent>
I tried Googling Pinnotherid and Pinnotheridae, but I haven't yet found another one that looks quite like this one.
Thanks again,
- Misael
<Mmm, well, my best guess to family is now the Trapeziidae... "coral crab" family... But my scant home references, mostly general marine invert. books, some regional, and Debelius' Crustaceans of the World, nor searches on Google with the family name, color characteristics, w/ or w/o the genus (Turbinaria) or family (Dendrophylliidae) show this animal... I suspect that it is mildly bothersome to the coral, but like yourself, I'd keep it as part of the livestock here. I am going to put your query in LynnZ's in-folder (she's much more adept at these ID's than I) and hope she or a browser will chime in w/ more.
Cheers, Bob Fenner>

Re: Follow-up Re: Crab ID -- 12/11/09
Bob and Lynn,
<Hello Misael, Lynn here this morning>
Thanks for all the great info on this little critter.
<On behalf of Bob any myself, it was a pleasure.>
From what I've seen so far, the gall crab seems to be the closest so far to what I have. I noticed it this morning in another hole nearby where it originally went into, assuming I have only one.
<Yep, if it is indeed a gall crab, there could be several females in the vicinity.>
Hopefully it'll give me more opportunities to take better pictures.
<Sounds great! Send them along when/if possible!>
Thanks again!
<You're very welcome!>

<Take care, LynnZ>

Follow-up Re: Crab ID -- 12/9/09
Hi Bob,
<Hi Misael, Lynn here chiming in today.>
Thanks for your quick response. I put it back in tank and it eventually crawled into a little hole in the middle of the coral that I never paid attention to before.
<Can be hard to see!>
Unfortunately, I didn't get any more pictures of it before putting it back and it's not really visible at the moment. I attached the same two pictures but at maximum resolution in case that's helpful.
<Thanks, every bit of information we can get is helpful.>
I tried Googling Pinnotherid and Pinnotheridae, but I haven't yet found another one that looks quite like this one.
<Like Bob, I've gone through a ton of sources but haven't found anything that exactly matches your little fellow either. Unfortunately, there are just so many crab species out there that even with very detailed photos, you're often lucky to narrow things to family level. One possibility, beyond what Bob offered, is a coral gall crab (family Cryptochiridae). Naturally, there are many genera within this family and many species beyond that. Unfortunately, I can only find photos of a few species within this entire family, but here are a few examples:
http://decapoda.free.fr/illustration.php?n=1&sp=2056
See photos towards the bottom of the page at this link: http://www.marinelifephotography.com/marine/arthropods/crabs/crabs.htm
The following is an excellent Adobe PDF file with ID keys for the family Cryptochiridae. Pay particular attention to the shape of the carapace in the various illustrations. Note the similar elongate proportions front to back, the shape/anatomy of the anterior/front leading edge (where eyes are), etc. :

The above link originated at this address: http://scholarspace.manoa.hawaii.edu/handle/10125/1293
This link should help with the various anatomical terms, etc., listed within the above PDF file: http://webs.lander.edu/rsfox/invertebrates/callinectes.html
Coral gall crabs live within half-moon to round shaped holes ('galls') formed within a coral as a result of the crab's irritation of its tissues. These crabs tend to live in pairs with the female eventually becoming trapped within the gall, while the smaller male is able to go out and about to feed and mate with other nearby females. Gall crabs are usually pretty small and reportedly feed on the host coral's mucus and a bit of tissue. Luckily, they don't seem to damage the coral enough to do significant harm. Personally, I'd leave the little fellow in there and enjoy watching him! Please see the following link for various examples of coral galls:

Re: LPS ID.. Now decapod ID, sans pic! 11/6/09
Hi Crew,
Bob, Thank you for your advice, I did not buy that coral...
Now I have one more question. A 7 months ago, when I just started my tank, I got live rocks. Then one month later I noticed one tiny crab, less then 1/4 inch, looked like green emerald, with hairy legs and same kind of feeding behavior, just completely black. This thing is growing so fast, and now it is about 1.5 inch. Is still crapping algae and does not bother other tank mates. I can not get a picture because it spend all the time between rocks. Can you tell me what it is, how save to keep it in my tank, and if it is not save, how to get rid of it?
<Nope>
Thank you very much for your help and everything you do to help people like me.
Best regards,
Igor

Mystery Crab: Likely Anomuran: Porcelain Crab -- 10/17/09
Hi
<Hello Jan, Lynn here this morning.>
I have a new Red Sea Max 1250 tank set up just with live rock for the moment and have 3 crabs? These have a large claw, small order pincer thing and banded legs but the body is tiny, much smaller than the big claw. They seem to feed by two feeler things which go up and down to the mouth in sequence and these have two large fans attached. Look a bit like a Spanish dancing girl!
<Heee! Very observant! What you describe is typical of Porcelain crabs (family Porcellanidae). Those 'fans' are used to filter organics/plankton from the water. For more information on these neat little 'false' crabs, please see the FAQ titled 'Mystery Crab (actually an Anomuran) -- Likely Porcelain Crab -- 8/16/09' at the following link: http://www.wetwebmedia.com/squatlobfaqs.htm >
Any idea what they are and if dangerous,
<Luckily, they're not dangerous to humans (beyond the possibility of getting pinched), but like most crabs, they're opportunistic critters so do keep them well fed as noted at above link.>
I have not yet put anything in the tank just cleaning crew snails and a blued legged hermit.
<Oh, you're just getting started! Enjoy the process and all the critters that show up, including these neat little guys!>
Many thanks.
<You're very welcome, it was my pleasure.>
Jan Randall
<Take care, Lynn Zurik>

Re: Mystery Crab: Likely Anomuran: Porcelain Crab -- 10/17/09
Hi Lynn
<Hi Jan!>
Many thanks for the fast reply.
<All due to your terrific description!>
I think the animal is an Anomuran although mine don't look like any picture so far, so is probably Anomuranrandallis!
<Heeee! There are many genera and species in the family Porcellanidae so identification to species level can be a real challenge. If you can get together some good photos though, and tell me where the crabs/rock originated, I'd be glad to give it a try. I may not get it to species level but I might be able to narrow it to genus. Even that can be an accomplishment! If you do get a chance to take some photos, try to get a good one from above showing the carapace, all the legs, and the claw arms. Also, if you can get a good close-up of both claws/arms, that would be terrific. The more detail you can capture, the better chance we have of success! Oh, and one last thing, if you remove the crab to a bowl of tank water to take photos (keep crab submerged), don't be too surprised if the little fellow loses a claw or two. These guys sometimes drop them when feeling threatened/stressed, but with good health/husbandry, they should be back within a few molts.>
Great to know I can ask the experts when I get stuck.
<Heeee! I'm no expert, but I'm happy to help anyway!>
Best wishes, Jan.
<Same to you, Jan. Take care, LynnZ>

Re: Mystery Crab: Likely Anomuran: Porcelain Crab -- 10/18/09
<Hi Jan>
Right, will have a go when I can.
<Sounds great. I look forward to seeing the little fellows!>

Stuff, Decapod ID ESP, More likely development of a content provider in our interest -- 10/22/09
Dear sir/madam,
<... will you read my book?>
I have two questions.
<I have considerably more. Let's start with yours though>
Firstly, I have a hitchhiker crab, I was wondering can you tell the type by it's cast off carapace?
<Perhaps>
I've been trying to lure him out, kill him, and trap him in a jar to no avail. I know that it has red eyes, a tanned body and two white stripes between its eyes. Just want to know what type it is. I can send a picture of the shell if needs be. The left over shell had small black spots on the claws too if that helps.
<Uhhh>
Secondly, I was reading on the site about some of the WWM team being writers for publications regarding aquatics and would like some advice. I work in a aquarium shop in Belfast (Exotic Aquatics), and I've got a degree
in newspaper journalism, and I'm interested in fish but I've been trying to write pieces on fish., on equipment, etc, and I just can't seem to transfer from news to fish. I mean, I know a good bit about aquatics but there's a
lot I don't too and I'm looking to get a bit of income out of writing so even just a few areas to stick my nose in an get a few stories would be good. If this could be passed on to Mr. Fenner or anyone else who publishes work, that would be kind of whoever has to read this.
Kind regards,
Bob Malcolm
