Sharks are very interesting fish with a lot of unique features. Most shark are very curious and swim close to the things they find interesting in order to check it out. You will see that a lot when they swim in giant aquariums, a lot of sneak peaking through the glass. 🙂
They are colourblind and see everything in black and white. They are great swimmers and have to stay in motion in order to breath. If you turn a small shark onto it’s belly, he slides in a trance right away and starts sleeping. Also touching the nose of a little bit too nosy shark can make them come further out of the water, laying their head back and open their mouth, and leave afterwards. Very special to see this behaviour on video!
