Hey, everybody! It's Otto, from Daisy and Otto! I'm here today to talk to you about one of the coolest ocean creatures. No, not otters, silly. Sharks! Sharks are one of the ocean's top predators, and here's a fun fact: sharks have been alive longer than trees! 400 MILLION years! How crazy is that?
Sharks come in all shapes and sizes. In fact, there are over 400 different species of sharks. Some are the size of a car, and some are less than a foot long. They have a variety of different color markings, depending on what kind of shark it is. Some sharks travel great distances. Some sharks live in the same area for all of their lives. Some sharks can even walk on shore! Just take a look at some different examples of sharks in the gallery below.
Did you know that there are species of sharks that don't even eat meat? Species like the Whale Shark or the Basking Shark feed on plankton, just like whales do, but most sharks are carnivores, which means they eat meat. Sharks are cartilaginous fish, which means their skeletons are made of cartilage and not bone - kind of like your ears.
Sharks are very important to the ocean, but many people still fear sharks. In fact, sharks are in a lot of danger because of over-fishing. The best thing you can do to help protect sharks is to share all the reasons sharks are our friends, to lesson the fear towards sharks.
