Nudibranch ID: Glaucus atlanticus 3/16/09
Hi,
<Hello, Lynn here this evening>
I was on vacation when I came across this Nudibranch in New
Smyrna beach in northeast Florida. He looks just like this....
http://www.naturalsciences.org/education/deepsea/images/nudibranch.jpg
<Beautiful little creature.>
He's still alive...I just need to know what kind of
Nudibranch he is.
<Its an Aeolid Nudibranch known as Glaucus atlanticus that
floats around the water surface upside down and is known to feed
on Portuguese man-of-war (Physalia spp.). By the way, this
creature is capable of delivering a nasty sting thanks to its
ability to store the Physalia venom, so whatever you do, avoid
all skin contact! For more information, please see the following
links:
http://www.seaslugforum.net/factsheet.cfm?base=glauatla
http://en.wikipedia.org/wiki/Glaucus_atlanticus
>
I want to keep him alive because he is very beautiful.
<Yes, it is very beautiful but has a specialized diet and will
not survive long in captivity. As long as the animal has been
kept by itself (not mixed with livestock in an established marine
system), the best thing to do is return it to the wild asap. Take
care, Lynn>

<Hi>
Thank you lots, but it died this morning.
<Im so sorry.>
I cried because it was so pretty.
<Not to mention the loss of life.>
Next time I see one on the beach, and if it's alive, I'll
pick it up with a clam shell and fling it back into the
ocean.
<Good thinking. Although tempting, it really is for the best
to leave wild creatures in their natural habitat.>
Now it's my new favorite ocean dweller, even though it's
basically the most poisonous thing in all the oceans.
<Well, they're not as bad as box jellyfish, geographic cone
snails/Conus geographus, or blue-ringed octopus, but I sure
wouldn't want to test it!>
Pretty but dangerous that's how it goes sometimes
<Yes indeed.>
lol...I see though that no one sells them probably because they
are too expensive to take care of :P
<Unfortunately, that hasn't stopped other such creatures from
being offered for sale, but in this case there's probably just not
enough potential profit to be made. Lets hope it stays that way!
Take care, Lynn>

Sea Slug ID Please Possible Dermatobranchus sp.
Nudibranch - 1/18/08 <Hello there, Lynn here this
evening.> I just found this. It is about an inch long and I
took a good photo of it. I need to know if its good or not before
I release it from its Tupperware container with holes poked in
it. I have been searching the net for a good hour now so I gave
up and am now asking you for help. <Heheee! You searched for a
whole hour, huh? You were just getting started! Okay, Ill let you
off the hook this time. :-) What you have looks a lot like a
Nudibranch in the Family Arminidae, namely a species of
Dermatobranchus. Please see the following link for photo
comparison and additional information:
http://www.seaslugforum.net/showall.cfm?base=dermspp These prey
on soft corals, so if you have any in your system, I wouldn't put
that little guy back in! For more information on Nudibranchs,
please see this WWM link (see Pt. 6 for captive care
information): http://www.wetwebmedia.com/nudibran.htm Take care,
Lynn>

Nudibranch and baby ? 12/11/08 G'Day Guys
and Gals, <Rick from Oz> I'm hoping you can educate me
on this little fella who turned up in my reef tank. (Image 1).
I'm assuming it's a Nudi of some description.
<Is...> Odd thing is I had a Chromodoris elizabethina that
showed up dead one morning with no apparent cause. I promptly
removed it from the tank but that very evening this showed up.
<Mmm, coincidence> Hopefully the pics are ok but if not
I'll attempt to describe it. <They're very nice...
looks to be a Phyllodesmium species...> If you imagine a sheep
with no legs or head, that's pretty much what it looks like.
Hence, I called him ?Woolly? :0) Its about 2
Ã'½ - 3 ? long when extended. I pulled it out
of the reef tank and put him in the QT until I could find out if
he is reef safe or not. I'm guessing no, but being such a
cool looking animal I am reluctant to dispose of it. Also, in
image 3, just under the lip of the ?castle tower? on the right
side, you will notice what appears to be white squiggles.
<Eggs...> The creature had sat in this location for a
period of time and when he moved this ?squiggle? remained. It
appears to pulse and looks to be thickening up, could it be off
spring? <In your tank at least, yes> Your help is much
appreciated Kindest regards Rick from Oz <Do a bit of
look-seeing here on the Net... in particular your
countryman's SeaSlugForum.net... Bob Fenner>

Re: Much more re: Nudibranch and
baby ? -12/11/08 Hi Bob, <Hello Lynn! Long time no
chat> Hope you're doing well after all your travels,
it's good to have you back! Hey, I was looking over the
queries last night before heading to bed and saw one regarding a
white Nudibranch sent in by Rick from Oz. I didn't have time
to tackle it then and didn't want to grab it if I
couldn't get to it right away. Anyway, I figured I'd snap
it up if it was still there this morning. Unfortunately, it was
already gone and the dailies weren't out yet - but I was
still curious as to what species Rick might have. I thought
I'd seen something similar a while back, but couldn't
remember the name - Arrghhh! <Mmm, yes... if memory serves,
you identified a member of this genus not long ago> The bottom
line is that after doing some research, I saw that you'd
answered the query (thanks for that!) and discovered that
we'd come to the same conclusion - that the Nudibranch was
likely something in the genus Phyllodesmium. I got lucky and
found a species that may be it, or similar, and if so, Rick might
want to get it out of there. In the main photo he sent (Image 1),
the Nudibranch is right next to what looks like a softie of some
sort. I'm not sure what type it is, but the Nudibranch
species I'm thinking of (Phyllodesmium magnum) has a taste
for softies/Octocorals - as in yikes! It sounds like they get
pretty large too - hence the term "magnum" I guess! At
2-3", his is already up there in size! Anyway, here are some
photos I found for comparison and there are many more at
seaslugforum.net through the links below
http://www.koretz.net/Eilat/Invertebrates/Molluscs/Nudibranchs/Pages/Pmagnum-1.htm
Factsheet on the species:
http://seaslugforum.net/factsheet.cfm?base=phylmagn
http://seaslugforum.net/display.cfm?id=7558 I'm not 100% sure
that's what species Rick has, but it's close enough that
I think it warrants keeping a close eye on those corals! Take
care, -Lynn <I do agree with you entirely... Will look, find
and send this info. to Rick. Cheers and happy holidays.

Chris/Pullz in Kona, diving, making pix... w/a rare
find? 10/23/08 I thought this was a Turberculous but it
was correctly identified as a Carbunculosa, if my eyes are seeing
things right.... The white line on the eyes seemed to be
correct.... thoughts? Chris <Pullz... you shot this pic in HI?
This Dendrodoris is not listed as coming from there... I've
never seen this species there... You might want to send this
along to SeaSlugForum.net. Cheers, Bob/DF>

Slug/Nudibranch ID Help Please 11/15/08 Good
Evening - <And morrow to you> Hope you all are well. I was
wondering if you folks could identify this creature that I found
in my tank last night. Of course, I've always heard the
saying, "When in doubt, take it out," which is what I
did; however, I just wanted to be sure I did the right thing.
Thanks - Wes <Mmm, well... does appear to be a Nudibranch...
I'd leave in unless it's eating something/s valuable. Bob
Fenner>

Nudibranch Photos-1 10/23/08 Dear Bob,
<Geo.>Your help.. once again. This Nudibranch was found in
Atalya (North Aegean) by a friend. Can you help to ID it ??
<Mmm, pretty sure it's of the genus Flabellina:
http://wetwebmedia.com/MolluscPIX/Gastropods/Opistobranchs/Nudibranchs/nudibran6.htm
But I'd send this (and all other Opistobranch ID questions)
to the SeaSlugforum.net> Many thanks in advance (as usually,
you can use the photo for your site... ) All the best, George
<And to you my friend. Bob Fenner> -- George J. Reclos
