Hong Kong Moray Eels


Moray eels are not very frequently seen because they are active at night and hide in crevices, but fisherman catch them quite frequently. HK has at least 15 species. Visually similar though not actually a moray eel of the Muraenidae family, is the pike conger (Muraenesox cinereus) which belongs to the family Muraenesocidae, but I have included it at the end for general interest.
