Fish, Sharks and Rays on SALE!
I think most of us know sharks and rays are fish (cartilaginous fish) so I won't use that one, but... Have you ever wondered how fish can stay in schools and move so well together? I thought maybe they just watch each other closely? I recently learned, however, that it's their lateral lines that make an impressive school of fish possible. The lateral line of pores lead to a chamber filled with groups of sensory hairs that pick up vibrations. It senses predators, prey, and it's schoolmates. They feel the rhythm! (Check out the King fish lateral line!)
