Family Gobiesocidae

There are currently 136 species of Gobiesocids in 36 genera (Fishbase). They are found in the Atlantic, Pacific and Indian oceans. Normally bottom-dwellers, many of them have pelvic fins which are modified into a sucking disk - rather like most of the gobies. Unlike gobies however they totally lack scales and are covered with a protective mucus. Some members of the family associate with invertebrates - the urchin clingfish below was swimming freely away from any host urchin.

The crinoid clingfishes pose a minor conundrum. They match their host crinoids very well - but how do they know? Do larval crinoid clingfish search out a featherstar of the color they "know" they are going to become or do they develop color to match that of their host? What would happen to a clingfish transferred to a host of different color? Could it change to match - and if so how quickly? Some much to learn - so little time.
