These mostly transparent shrimp were often seen around black corals, gorgonians or hydroids.
The coiled structure inside the one in the next few shots is apparently an internal flatworm parasite in the order Fecampiida.
Those below might be the same species although they look and seem to act a bit different. I have not seen the species congregating on sponge like this before.
