The 14th of July is Shark Awareness Day! That means it is officially time to celebrate the ocean’s most recognisable predator. This day is also meant to address the negative image surrounding sharks and help us realise that they are not what Hollywood makes them out to be!

Shark heritage

Scientists believe that sharks have been around for more than 400 million years. That’s about 200 million years before the dinosaurs came to be! The first true shark was called the Cladoselache. What a horrible name, right?! Don’t worry. They have been extinct for many years. Their fossils have remained, however, and they teach us that sharks are one of the oldest animals to remain on Earth.

This fossil is good evidence of what Cladoselache looked like.

Modern sharks

These days, sharks are feared, and mostly it is for a good reason. They are ferocious predators. But they are not the villains that many people make them out to be. Sharks have no need to eat humans. In fact, they hate the way we taste! They would much rather eat fish and other marine life.

Shark conservation

There are many groups and individuals that are trying to save sharks every day. About one-third of the sharks in the ocean are in danger of extinction. This is because of overfishing and other elements. Scientists tag sharks with special tracking gadgets to keep an eye on them. They also use this to learn all about how far they can swim, where they like to go, and how big different groups of sharks get. All of this information and more is vital to the saving of our sharks.
