New record and morphometry of the bluntnose sixgill shark Hexanchus griseus (Chondrichthyes: Hexanchidae) in Baja California Sur, Mexico
ABSTRACT We report the first record and morphometry of a complete juvenile Hexanchus griseus female shark, caught in Punta Lobos, Baja California Sur, Mexico. The oceanographic conditions of the area, where the specimen was caught, coincide with the habitat previously described for this shark specie...

The oceanographic conditions of the area, where the specimen was caught, coincide with the habitat previously described for this shark species, with low temperature, stable salinity and high hydrostatic pressure.
