WAbyssobrotula galatheae, is a species of cusk eel in the family Ophidiidae. It is the deepest-living fish known; one specimen, trawled from a depth of 8,370 m (27,460 ft) in the Puerto Rico Trench in 1970, holds the record for the deepest fish ever captured. Although generally recognized, some have suggested that the record-breaking individual might have been caught with a non-closing net and therefore perhaps caught shallower.
WThe amber darter is a small, endangered species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is native to the Conasauga River and Etowah River in Georgia and Tennessee in the United States. It typically inhabits riffle areas over gravel and sand bottoms, hiding in aquatic vegetation when present. It feeds on small invertebrates and probably breeds between late fall and early spring.
