Greenland Shark

 

(Somniosus microcephalus), a fish of the suborder Selachoidei. The spindle-shaped body reaches a length of 6.5 m and weighs approximately 1 ton. The Greenland shark inhabits the northern Atlantic Ocean and adjacent regions of the Arctic Basin. In the summer it remains at depths to 1,000 m, and it rises to the surface in the winter. The shark feeds on fish and invertebrates. It reproduces in the spring, laying approximately 500 soft eggs having no horny capsule. The Greenland shark, which was at one time commercially important, is not harmful to humans.

Asimismo en las aguas profundas del Golfo de Mexico donde la temperatura es cercana a los 4[grados]C, se capturo y registro recientemente la especie Somniosus microcephalus, un tiburon que habita en aguas frias del Atlantico norte (Benz et al., 2007; Benfield, Thompson, & Caruso, 2008); esto evidencia, que puede existir una distribucion continua para diversos condrictios dada por la temperatura, presente en el gradiente batimetrico.

Although the very large (up to 7 m in total length [TL]) Greenland shark (Somniosus microcephalus) may have the northernmost range documented for species of this genus, the range of the Pacific sleeper shark extends into the Bering Sea and past the Arctic Circle (Bright, 1959; Orlov, 1999; Orlov and Moiseev, 1998, 1999; Benz et al., 2004; Hulbert et al., 2006; Courtney and Sigler, 2007).
