Meet #SpongeBob’s real-life best friend Patrick! Starfish, though marine creatures, are not true fish – they do not have gills, scales, or fins like fish do. They can’t propel themselves with their arms, but they use their tiny tube feet to move along the sea bed. Though starfish have no blood, they use filtered sea water to pump nutrients through their nervous systems. They are strong hunters and eat by extending their stomach and mouth over the soft body parts of their prey!
