The Blacknose shark belongs to the Carcharhinidae family. It has an average size of 1.4m for 10 kg. It has a maximum lifespan of 19 years. It mate in late May to June. It can be fished all year round.
The Black Nose Shark has a slender body with a long rounded snout and large eyes. The inhalant and exhaling openings of the nostrils are separated by a skin flap. There are respectively 12 to 13 and 11 to 12 rows of teeth on each side of the upper and lower jaws, with one or two teeth at the symphysis level. The teeth are triangular and oblique, with serrated edges. The upper teeth are thicker than the lower teeth. The five pairs of gill slits are short, measuring less than one-third of the length of the base of the first dorsal fin. The first dorsal fin is small and somewhat sickle-shaped, with a pointed apex and a short, free posterior border; its origin is at the free rear edges of the pectoral fins. The second dorsal fin is relatively large, but always less than half the height of the first. There is no ridge between the two dorsal fins. The pectoral fins are short and tapered. The body is covered with overlapping dermal denticles that have five to seven longitudinal veins (three in very young individuals) ending in three to five teeth. The coloring is a yellowish grey to greenish on the top and white to yellow below. A characteristic dark spot at the tip of the snout is more or less visible, especially in young sharks.

The Blacknose shark lifestyle

The Blacknose Shark is a small and lively predator, feeding on small fish such as Salmon Saar (rhomboid Lagoon), Sciaenidae, Sparidae, Anchovies, Ostraciidae and Diodontidae, as well as octopus and other cephalopods.
Like other sharks of the Carcharhinidae family, the Blacknose Shark is viviparous: after developing embryos have exhausted their yolk supply, the empty yolk sac develops in a connection with the placenta that allows the embryo to be fed by the mother. Vitellogenesis (formation of the yolk in the ovary) occurs in late summer, and is immediately followed by copulation and fertilization in the fall; the young is born the following spring or summer. Females generally give birth to one to five young in shallow waters, such as coastal bays or mangroves. The Black Nose Shark reaches maturity at the age of 4 to 5 years, regardless of sex.

The Blacknose shark habitat

The Blacknose Shark lives on the continental and island shelves off the east coast of the Americas, from North Carolina in the north to southern Brazil in the south, including the Gulf of Mexico, the Bahamas, and the Caribbean Sea. It frequents coastal waters in habitats such as seagrass beds or soils made of sand or shell and coral debris.
