Walking fish

Also found in: Thesaurus, Encyclopedia, Wikipedia.
(Zool.) any one of numerous species of Asiatic fishes of the genus Ophiocephalus, some of which, as Ophiocephalus marulius, become over four feet long. They have a special cavity over the gills lined with a membrane adapted to retain moisture to aid in respiration, and are thus able to travel considerable distances over the land at night, whence the name. They construct a curious nest for their young. Called also langya.
