A number of species, especially in the genus Bathypterois, have elongated pectoral and pelvic fins. In the case of the tripodfish, Bathypterois grallator, these fins are three times as long as the body — up to a meter in length — and are used for standing on the sea floor. Ipnopids either have tiny eyes, or very large eyes that lack any lens; in either case they have very poor vision and are unable to form an image.[1]
