STAR SEA-Emir

• Starfish or sea stars are one of the most familiar of marine invertebrates. Starfish are commonly has five arms. Many species are brightly coloured in various shades of red or orange, while others are blue, grey or brown.

• Starfish does not have brain, blood, and eyes. Even though they do not have eyes, they are not completely blind. They can sense light and shapes through an eyespot (an organ that sensitive to light) that located at the tip of their arms.

• Some starfish like to eats snails, sponges, sea anemones, coral, or the other starfish. And some will eats any kind of small animal they can get. But, usually they eat animals such as mussels, clams, and oysters. They use their arms to force open and eat the clams or oysters. Sea stars can “smell” food in the water. But, of course, they don’t use noses to do this smelling. Sea stars don’t even have nose. They can detect chemicals in the water that come from food by their sensitive cells on their skin.

• The starfish can live all over the world. If you are looking for a starfish they are usually in rocky places. Also sea stars can swim all the down to the bottom of the sea or they can relaxed and float on top. The Ochre sea star can live any where from Alaska to California. The Ochre sea star can also climb up to the top of the wall and stay there for more then 5 hours. Most sea stars are in small groups or alone. There is a sea star called Crown-of-Thorns and they live coral reefs. 

• Sometimes predators bite their arms and often accidentally rocks fall and crush them. But they can grow their new arm, just like autotomy in lizard. Some think that starfish are mysterious and unusual creatures because of their spiny skin but there is nothing to be afraid of, starfish are harmless to humans .
