Sharks breathe through gills and have a streamlined body with a nearly circular cross-section.
They are mostly predators, feeding on fish, crustaceans, and sometimes marine mammals, but some species filter plankton from the water.
Sharks have teeth that are used to grab and tear prey, but they are not used for chewing.
Sharks have a sensitive sense of smell and can detect blood in the water.
They reproduce internally, with most species being viviparous (giving birth to live young).
Sharks are classified into nine orders, with over 370 species.
Not all sharks are dangerous to humans, with only about 10% of species posing a threat.
Shark attacks are rare and often non-fatal, with most attacks occurring on surfers and swimmers.
Sharks are important to the ocean ecosystem, but many species are threatened due to overfishing.
