Blacknose sharks are named for the dark patch on their snouts,
though the markings may be indistinct in older individuals.
Size Average 3.5 feet long and 40 pounds
Diet Small fishes and cephalopods
Lifespan 16 to 19 years
Range Blacknose sharks can be found in the Western Atlantic,
from North Carolina to Brazil, including the Gulf of Mexico
Habitat Juvenile blacknose sharks frequent shallow waters over seagrass;
adults can be found in deeper waters over rubble, shells or sandy flats
Predators Their main natural predators are larger sharks, however humans
kill many thousands of sharks every year.
Relatives More than 500 shark species have now been identified, and many of them grow to less
than 4 feet long. Blacknose sharks are from the Carcharhinidae family of requiem sharks,
known for their rounded nose and streamlined shape.
Family life Blacknose sharks are viviporous, which means they give birth to live young. Litters of three to six live pups are born in shallow bays or mangrove swamps. It takes at least four years for these sharks to reach sexual maturity.
Conservation status Vulnerable They are fished commercially in some places where their meat is sold dried and salted for human consumption. U.S. shrimp trawl fisheries also pose a major threat to these sharks, as considerable numbers of juvenile sharks are caught as bycatch. Sharks grow slowly and reproduce at low rates, so many species cannot withstand the pressure of commercial and recreational fishing.
