The Sharks 

BULL SHARK Carcharhinus leucas

bull

Habitat
Common apex predator that inhabits estuarine, nearshore and offshore waters of both the Gulf and Atlantic coasts of Florida. Commonly enters estuarine waters and is one of the few shark species that may inhabit freshwater, sometimes venturing hundreds of miles inland via coastal river systems.

Size/Age
Maximum size about 11 feet. Matures at approximately 14-18 years of age (about 6.5 feet) and is estimated to live 24+ years.

Human factors
Constitutes only a small portion of the commercial shark fishery. Hardy species; does well in captivity. One of the more dangerous shark species, accounting for the third highest number of attacks on humans.

NURSE SHARK Ginglymostoma cirratum

nur

Habitat
An abundant, coastal, tropical and subtropical shark that inhabits nearshore waters of both the Gulf and Atlantic coasts of Flordia. Often seen lying motionless on the bottom. Preferred habitats are coral reefs, rocks, and mangrove islands..

Size/Age
Maximum size about 9 feet. Matures at approximately 7 feet and is estimated to live 24+ years.

Human factors
Valued in the Caribbean for its high quality hide, but is considered a nuisance species in most North American longline fisheries with fins and meat of little value. Does well in captivity and has been used in many physiological and immunological studies. This sluggish bottom-dwelling shark has been involved in only a few attacks on humans, most of which were provoked.

The Scalloped Hammerhead Shark (Sphyrna lewini)

the

Scalloped hammerhead shark is predatory, feeding mainly on fish, squid, and stingrays. It has a distinctive flattened head extending to hammer-like lobes on each side. It can grow quite large — it is common to 6 feet and can reach 20 feet. The Florida record is 991 pounds. It is often confused with the much less abundant but larger great hammerhead and can be distinguished from the great hammerhead by the curved backside of its head, which differs from the straight edge found on the great hammerhead

BLACKTIP SHARK Carcharhinus limbatus

blacktip

Habitat
Common in Florida’s coastal waters, bays and estuaries. A very active, fast-swimming shark often seen at the surface. Often forms large schools during annual migration times. Migrates southward and into deeper coastal waters during winter months. May leap out of the water and, like the related spinner shark, spin around several times before dropping back into the sea.

Feeding
Feeds primarily on fishes but also eat small sharks, some rays and skates, squid, crabs, octopus, and lobster.

Reproduction
Gives birth to live young. Litters contain 1-10 pups. Females swim into shallow bays in spring and early summer to give birth. Size at birth 22-28 inches.

Size/Age
Maximum length about 6 feet. Matures at approximately 6-7 years of age(about 5 feet) and is estimated to live 10 + years.

Human factors
Valuable commercial species with marketable flesh, hide, fins, and liver. One of the most commonly collected sharks in the commercial fishery. Fished for sport on light tackle and often leap out of the water when hooked. Has been implicated in attacks on bathers.

BONNETHEAD SHARK Sphyrna tiburo

bon

Habitat
Abundant in nearshore Florida waters. Commonly seen over shallow sand and mud flats. Moves into deeper coastal waters during the colder months.

Feeding
Feeds primarily on crabs, shrimp, mollusks, and small fishes.

Reproduction
Gives birth to live young. Litters contain 4-16 pups. Size at birth about 12 inches.

Size/Age
Smallest member of the hammerhead family. Maximum length about 3.5 feet. Matures at approximately 2 years of age (about 30 inches) and is estimated to live 7+ years.

Human factors
Edible, but marketed mostly as crab bait. Good sport fish; use light tackle with live shrimp or cut-bait. Harmless to humans. Often displayed in aquaria.

LEMON SHARK Negaprion brevirostris

lemon

Habitat
An abundant, inshore tropical shark that inhabits both estuarine and nearshore waters of the Gulf and Atlantic coasts of Florida. Commonly enters estuarine waters and often ventures into freshwater areas, but does not penetrate as far up rivers as the Bull shark. Migrates southward and into deeper waters in the winter months.

Feeding
Feeds on a variety of bony fishes, crustaceans, mollusks, rays, small sharks, and occasionally on sea birds.

Reproduction
Gives birth to live young. Litters contain 4-17 pups. Size at birth about 2 feet. Utilizes shallow bays and coastal lagoons as nursery areas.

Size/Age
Maximum size about 10.5 feet. Matures at approximately 11-12 years of age (about 8 feet) and is estimated to live 27+ years.

Human factors
Constitutes only a small portion of the commercial shark fishery. Does well in captivity, with young individuals being favorite subjects for physiological and behavioral studies. Has been involved in only a few attacks on humans.
