All About Sharks for Children- Animal Videos for Kids

Sharks are a fish that can measure up to 32.8 feet and weigh up to 20.6 tons. They fall into a subclass of species called elasmobranchii, which means their skeleton is made from cartilage rather than bones. Sharks can also have up to seven gills at each side of their head, which is uncommon as most fish only have one.Show more

Based on scientists findings and examining fossilised teeth from sharks, they believe that sharks have been around for 400 million years - this means they've outlived dinosaurs! Today sharks have evolved hugely and there are approximately 1,000 species of sharks and rays, with new ones discovered every year.

Whale Sharks are one of the biggest species of fish on earth and can actually grow up to 55 feet - that's a big jump compared with dwarf lantern sharks that only measure up to eight inches.

Sharks are predators and have multiple rows of pointy teeth - did you know they fall out and routinely grow back on a routine basis?

Shark behaviour
Some species of shark, for example, white sharks are solitary and don't stay in groups. Whereas others do like to swim in groups, for example, Lemon sharks have been seen to socialise in groups.

Most sharks eat small fish and invertebrates, but there is a few that prey on large species such as seals, sea lions and other marine animals.

What do sharks eat?
Sharks are carnivores, most of their diet comes from fish and other sea mammals including dolphins and seals. However, some shark species have also been known to eat turtles, seagulls, krill and plankton. When sharks are hunting for their prey, they use their lateral line system. They use this to help them detect water movements, which can be great during the night when visibility is poor.
