Recommended Posts

Any clues about these small amphipods living on hydroids in the Grand Cayman. Seem common and jump about a lot!

And are these the same species that live in the centre of the solitary gorgonian hydroid? Or android as Gordon calls them!

So I am an Engineer and not a Marine Biologist!

 

I don't think my photo adds to the search for identification as it was taken with a 60mm on D200 with Woody Diopter.

Just comparing the antennae shows you have 2 different species - probably genera - in your picture Alex, and Gordon has something entirely different. Gordon's is probably a true commensal. Members have posted pics of it before but there's nothing in the literature that I could find on it.
