Triakis semifasciata Leopard Shark Shark Order Size & Weight What it eats Teeth Reproduction Habitat Shallow sandy flats and confined muddy bays.
Occasionally near kelp beds on rocky substrate. Characteristics Large dark saddles (spots) extended from their head along their back.
The center of the saddles are lighter in mature adults.
The saddles are separated by smaller dark spots, on a background of light grey/brown. Males average to be about 150 cm (4.9 ft) max, and weigh up to 35lbs.

Females are 180 cm (5.9 ft) max and are around 40lbs at full size. The leopard shark pretty much eats whatever it can get.

Mostly eats invertebrates, crabs, shrimp, clams, octopus, bony fish, guitar fish and bat rays. Leopard sharks teeth can be described as narrow and long.
They periodically loose their teeth and are replaced within 9-12 days. The Leopard Shark is in the Carcharhiniformes order, which includes hammerheads, requiem sharks, smoothound sharks and catsharks. The leopard shark is in the Triakidae family, all the sharks in the family are smoothhound sharks. Color Body Elongated and slender. The second dorsal fin is rather large. Pectoral fins are shaped like hooks. Snout is broadly rounded with widely spaced nasal flaps that don't reach the mouth. \ Normally found along the pacific coast of North American. Life Expectancy Leopard Sharks can live up to 20+ years in proper marine life settings. The leopard shark reproduces by ovoviviparous.
The females produce eggs that are fertilized by the males.
The egg has no yolk sac placenta.
12 month gestation period.
Takes about 10 years to reach full maturity, very slow growing. What is Ovoviviparous? A form of reproduction where:
- Embryos develops inside the egg.
- Stays inside the mothers body until ready to hatch.
- Born live.
