The cyclops shark is pictured next to one of its siblings, which is normally colored, with a blue-gray back and white underside.
Dusky sharks, which average about 10 feet (3 meters) long as adults, are among the slowest growing of the shark species and can live for up to 45 years.
Often illegally harvested for its fins, the shark species is considered vulnerable by the International Union for Conservation of Nature.
