Shrimps, Order Natantia

Alpheus species at Steve Pro's

Family Alpheidae, Pistol Shrimp

Seldom seen, often heard... and the results of their "shooting" known far and wide... the Alpheids can be easily identified (if you can find them) by their very short eye stalks and one much larger "pistol" claw.  This specialized appendage is capable of punching holes in all crustacean exoskeletons, even many shellfish! Alpheus and Synalpheus species are the notable symbionts with Shrimp Gobies.

Pistol Shrimp are the predominant crustaceans on the world's reefs... and so you are likely to run into them... they eat most all types of foods... and if kept fed will often leave other crustaceans and mollusks alone. See happily fed specimen above in title bar.

Snapping Shrimps, family Alpheidae. Noted for their noise making capacity, myths re the power of their large claw (a .22 caliber, tank-cracking...) and commensal to mutualistic relationships with fishes (mainly Gobies) and invertebrates. 

Synalpheus stimpsonii (Man 1888). White body with varying dark markings. A crinoid (Comanthina, Oxycomanthus) commensal that often displays contrasting color to its host. East Indo-West Pacific; Singapore, Thailand, Indonesia, Japan, Australia. N. Sulawesi pix.

To-Be-Identified Shrimp 12/16/12
Hi Bob,
 <Lynn>
Just saw the gorgeous shrimp from IZOO, listed as “to-be-identified”, on today’s dailies.  It appears to be Alpheus soror, aka the “Bullseye Pistol Shrimp”.
<Ah yes; thank you>
  I’ve seen them available on the ‘net listed as such, but found a listing in Debelius’ Crustacean Guide of The World (2001), page 147.  It lists length up to 3.5cm, distribution as “Maldives, Sri Lanka, Philippines, probably widespread to IWP”.  It also goes on to state that the two photos listed “show an undescribed species, possibly of the Alpheus diadema-group. It has purple walking legs, and a conspicuous large ocellus on the second abdominal segment.”.  Hope that helps! 
 <Indeed it does... And I do have this work... in fact, Helmut is an olde (we're no longer middle age) friend... He and friends met up w/ us some Interzoo's ago in Dipelsdorf! >
Take care,
-Lynn Z
<Will do. Now down in Cozumel; sans JoshS unfortunately. His cold/flu is too bad. BobF>
<I'm sorry to hear about Josh, but am glad that you're no doubt having some good times/diving in Cozumel.  Enjoy and Happy Holidays! -Lynn
<<Ah yes. And to you and your husband. BobF>>
