Crinoid shrimp are small reclusive crustaceans that like to hide within the arms of crinoids on the reef. They are so well camoflauged that many divers overlook them. Dive guides will frequently push them out of their hiding places with their pointers, but I don’t like it when they do that. This one, however, was sitting right out on top of an arm, and the dive guide just pointed to it as we came across it. It was a nice, vibrant yellow.
