What is the correct name Sea stars or Starfish? Actually, both names are correct, neither is wrong. Even though there is a fish in the name, they are not really fish, they are related to sea cucumbers. Their body is shaped like a five point star (hence the name), but they can have more than 5 arms. They are usually yellow, orange, brown or red with contrasting pattern. Their circulatory system is pulsing six times per minute, the movement of the fluid is helping to carry nutrients through their body. The sea stars move very slowly, the average distance is less than 10 inch / 25 cm in a minute. They can move in any direction, following one of the five arms.
The starfish cannot survive when they are not in the water. You can see them sometimes on the beach, but if they do not get back into the sea quickly, they will die. They will have an electrolyte imbalance, because water has to constantly run through the tubes in their bodies. They are sea creatures, meaning they will only survive in salty waters, they cannot live in freshwater. There are over 1,500 types of starfish, the most common type is Cushion Sea Star and that is the one you can see when you go for a trip to Piscina Natural. When you see them, please do not lift them out of the water. We would like to show them to the next visitors too.
