Description
The Atlantic sharpnose shark has a long snout and
labial folds around its mouth. The triangular smooth edged teeth are similar on
both the upper and lower jaws. This shark can be brown, olive-gray or blue-gray
turning to white on the underside. Adults may have some white spots and smaller
individuals tend to have black edged dorsal and caudal fins.
Range
This small shark is more commonly found in the coastal
waters of South Carolina, Florida and the Gulf of Mexico where it is a year
round resident. Although its scientific name may suggest that it can be found
off of Newfoundland, the Atlantic sharpnose has not been reported in those
waters. Indeed, it is not a common shark anywhere in Canadian waters. Its most
northerly distribution is in the Bay of Fundy and it is rare even in that area.
Habitat
The Atlantic sharpnose shark is found in coastal
waters at depths of 12 meters (42 feet) or less during the summer months. During
the winter this shark can be found at depths greater than 27 meters (90 feet).
Life History
The Atlantic sharpnose shark is a small shark that
attains a maximum size of 1.2 meters (4 feet). Average size is about 95 cm.
Diet
This shark consumes shrimp, molluscs and small fishes.
Reproduction
Sexual maturity is reached when an individual is
approximately 83 cm (33 in). The young are nourished within the female as
development is viviparous. Litters of 4 to 7 pups are born in June in shallow
waters or estuaries. The newborns are 22 to 35 cm (9 to 14 in) in length.
Interaction with People
The Atlantic sharpnose is a common nuisance to
fishermen as it will take bait intended for other fish. It is a small shark and
not considered dangerous to humans.
