What are sea stars?
Sea stars are animals! • They are not fish! Although commonly called starfish, these animals are not fish. So we prefer to call them sea stars. • Sea stars have five-part symmetry Many common stars we see have five arms. Although some may have more arms, or less arms. • Sea stars need sea water Instead of blood, a sea star uses sea water to pump its body parts and move. Water inside the sea star may also help it keep cool at low tide. So please don’t remove sea stars from the water for too long. • Let’s NOT take the group photo with each person holding the sea star in the hand. Let’s put the sea stars in the water and get close to them for the group photo. • See also why we should not pick up sea stars on the wild shores of singapore blog. • Stars are fragile! When stressed, a star may purposely drop off an arm. Just like a gekko drops its tail. So don’t carry the sea star by the tip of an arm. The star might think a predator is chomping on it and will purposely drop off the arm. • Par
