Nosed Shark or Shark Knopp (Bignose Shark) is a species of the family Carcharhinidae. It is very common in the waters off in benthic areas close to marigin of the continental shelf at depths of 90-430 meters and feeds on bony fishes, such as lizard fish, Southern basses, soles and bat fish, other elasmobranchs, such as sharks, dogfish and parsnips and cephalopods. Although it is quite large and therefore potentially dangerous, its preference for deep water means that humans come into contact with him only very rarely.
C. altimus is a large species with fairly slender body, long face, broad and rounded, large round eyes. In appearance resembles very much the night shark (Carcharhinus signatus). On each side of the jaw and teeth 14-16 there are one or two small sinfisial teeth. The upper teeth are large and triangular, with serrated edges, while the lower ones are narrower and slightly serrated margins. The color is light gray, sometimes with reflections bronze, on the back and white on the belly; on the sides there is a white band. The culmination of all the fins, except those pelvic, is dark and the interior angles of the pectoral fins are blackish. This species can reach 3 meters in length and 168 kg in weight.
Reproduction is viviparous and the developing embryos derive nourishment from the yolk sac placenta. Births take place in August and September in the Mediterranean and in September and October off Madagascar. Each nest contains 3-11 small, 70-90 cm long.
