Tiger shark TIGER SHARK
Galeocerdo cuvier


GENERAL DESCRIPTION
The tiger shark has tiger-like markings on a dark back with an off-white underbelly. Pups have spotted markings that grow together to form stripes that fade with maturity. It has a large, thick-body with a blunt snout. The first dorsal fin is much longer than the second. The caudal fin is long and pointed. There is a dermal ridge along the back between the 2 dorsal fins. Color-Adult: gray-brown on top, off-white belly, young shark: dark stripes on the back.

Tiger sharks have a special gill slit (a spiracle) behind the eyes that provides oxygen flow directly to the eyes and brain. It also has a very good sense of smell, electroreceptors sensitive to electric currents in the water, and keen eyesight.

TEETH
Tiger shark teeth are very serrated (saw-edged), razor-sharp, and curved. The teeth are the same in upper and lower jaws

The teeth are located in rows which rotate into use as needed. The first two rows are used in obtaining prey, the other rows rotate into place as they are needed. As teeth are lost, broken, or worn down, they are replaced by new teeth that rotate into place.

SIZE
Tiger sharks grow up to 20 feet (6 m). On average they are about 10 feet (3 m) long.

DIET AND FEEDING HABITS
Tiger sharks will eat fish, turtles, crabs, clams, mammals, sea birds, reptiles, other sharks, and just about anything else that they can catch alive.

DISTRIBUTION

SPEED
Tiger sharks swim at an average speed of 2.4 mph (3.85 kph). They can swim in fast bursts, but can only sustain these high speeds for a few seconds..

REPRODUCTION
Tiger sharks reproduce via aplacental viviparity; the young of tiger sharks are born live in litters of between 10 and 82 pups. Gestation takes about 9 months. At birth they are 20-30 inches (51-76 cm) long and are completely independent.
