Pegasus sea moth
They are usually found in pairs, walking on their modified pectoral fins along sand and rubble. You can often observe them stirring up the sediment with their fins and feeding on small crustaceans hiding underneath the sand. Unusual critter, relative to the seahorse family. It can be mistaken for the Slender sea moth, which is quite rare, but also occasionally seen in Lembeh. Pegasus sea moth has a chubbier body and thicker snout.
