Basking shark feeds on plankton and there are hundreds of very small hooked teeth inside its mouth. These teeth are arranged in more than 150 rows. Each tooth measures about 5 to 6 millimeters in size. The teeth in the middle are triangle-shaped while the side teeth are hooked and are cone-like. In the middle of its jaw, the tiny teeth are spread out. Most of them are not used in eating at all and only 3 rows from the upper jaw while 6 rows from the lower jaw are busy in feeding.
