Pacific Leaping Blenny: Study Sheds More Light on Life of Legless, Land-Dwelling Fish

The Pacific leaping blenny is a 4 to 8-cm-long tropical fish found in reefs in Samoa and the Marianas, Society, and Cook Islands, in the western and southern Pacific Ocean. It remains on land all its adult life but has to stay moist to be able to breathe through its gills and skin.

Pacific leaping blennies move quickly over complex rocky surfaces using a unique tail-twisting behavior combined with expanded pectoral and tail fins that let them cling to almost any firm surface. To reach higher ground in a hurry, they can also twist their bodies and flick their tails to leap many times their own body length.
