The mud-dwelling moray,[1] Diaphenchelys pelonates, is an eel of the family Muraenidae, and the only species in the genus Diaphenchelys. It was described by John E. McCosker and John Ernest Randall in 2007.[2] It is a marine, tropical eel which is known from Indonesia, in the western Pacific Ocean. It dwells at a depth range of 15mto32mm (49feetto105feetm), and inhabits muddy bottoms, from which its species epithet, "pelonates" (translating literally as "mud dweller", from Ancient Greek, and treated as a noun in apposition), is derived. Males can reach a maximum total length of 46.5cm (18.3inches).
