Biology & Habitat

Appearance

Blacknose sharks are relatively slender, with greenish or yellowish-gray bodies and paler bellies. Their first dorsal fin is small and sits over or behind the tips of the pectoral fins.

Biology

Blacknose sharks live up to 20 years. Females grow slower, live longer, and reach a larger size than males. Additionally, both sexes grow more slowly in the Gulf of America than in the Atlantic. The average age of maturity in the Atlantic is 4.5 years for females and 4.3 years for males.

Where They Live

Range Blacknose sharks are found in the western Atlantic Ocean from North Carolina to southern Brazil. Their range includes the Gulf of America and Caribbean Sea. Habitat Blacknose sharks live in coastal waters over sandy, shell, or coral bottoms. Juveniles typically live in shallower areas while adults prefer depths of 59 to 210 feet.
