Diet: Some sharks are opportunistic feeders, preying on weaker species. The diet of sharks vary from species to species, they will eat almost anything including: fish, crustaceans, molluscs, marine mammals, and other sharks. Sharks eat 1-10% of its total body weight per week.

Senses: Sharks have keenly attuned senses, with an exceptional sense of smell. Sharks also have an acute sense of hearing. The strength of eyesight in a shark varies from species to species. It is also apparent that sharks have taste buds, and will reject food that is not a normal part of their diet if it doesn't "taste right".

Description: Sharks are a type of fish with a full cartilaginous skeleton and a highly streamlined body. Sharks breathe using five to seven gill slits.

Communication: It is thought that sharks do not communicate through vocalization, like many marine mammals, but instead relies on body language to communicate.

Did You Know?


The earliest known sharks date from more than 420 million years ago.


Behavior:
Only some species of shark migrate. Among the shark species that do migrate, the distance may be short or long.

Gestation / Birth: Sharks give birth three ways different ways depending on the species oviparity, viviparity and ovoviviparity. Most sharks are ovoviviparous, meaning that eggs hatch in the oviduct within the mother's body and that the egg's yolk and fluids secreted by glands in the walls of the oviduct nourishes the embryos. The shark pups born via ovoviviparous are alive and fully functional. Some species are oviparous like most other fish, laying their eggs in the water. Shark can also be born viviparity, in a method more analogous to mammals than fish, by maintaining a placental link to the developing young. Sharks born via viviparity are born fully functional.

Life Span: The life span of sharks varies from species to species.

Did You Know?

Shark pups begin their hunting and killing before they are even born by consuming their weaker siblings inside their mother’s oviduct.

Social Structure: Some shark species hunt in packs, which can exceed 100 animals other shark species prefer to hunt alone.

Athleticism: Sharks swim an average of 5 mph, but are able to exert bursts of much greater speed of more than 30 mph.
