Ogilbia galapagosensis
Ogilbia galapagosensis, the Galapagos cuskeel, is a species of fish in the family Bythitidae. It is only known from four brackish-water cave systems on Santa Cruz Island, Galápagos, Ecuador. Although usually called a cavefish, it has been argued that this label is inaccurate, as the places it inhabit also can be described as lagoon crevices. References
