Ophisternon is a genus of swamp eels found in fresh and brackish waters in South and Southeast Asia, New Guinea, Australia, Middle America and West Africa.[3] Two species are blind cave-dwellers.[4]
Well-preserved fossil remains of an Ophisternon sp. are known from the early Pleistocene-aged Laguna Formation of the Philippines, representing the oldest known fossil record of this genus.[5]
