Are starfish really fish?

Starfish live in the water, but this is where they resemble fish. They do not have scratches, scales or fins. Starfish live only in salt water. In fact, seawater replaces blood to pump nutrients into the body through the "water vasculature".

In addition, the starfish moves using a small pin on the underside of the body. An adult sunflower starfish can run at an amazing rate of 1 meter per minute using 15,000 pins. Pins can also help starfish prey on their prey

Starfish is related to gold dust, sea urchin, and sea cucumber. These are all echinoderms. That is, they have 5 radial symmetries. But this does not mean that all starfish have 5 weapons and species, only 10, 20, or 40 weapons exist! When one of the arms is lost, starfish will have amazing ability to regenerate.

Last week, tourists asked if they called starfish as starfish or as starfish. At the Grant Museum, our asteroids are marked as Starfish. Obviously, this confused name has led the child and adult to distinguish starfish from fish rather than echinoderm. Sometimes, we get similar inquiries from visitors and students that occur when scientific deflation encounters a common name. As another example, please have Paolo Viscardi, a colleague at Horniman Museum explain clearly that Apes is a monkey at once.

One morning, a huge wave threw hundreds of starfish on the beach. Starfish can not live outside of water for a long time. The boy ran around. He looked at starfish everywhere on the beach. He crooked and picked up the starfish and threw it back into the sea. He picked up another throw and threw it into the sea. Then he picked up the third and threw it back into the sea

You may know that the starfish is starfish, and the name of the star is usually well-known. However, starfish is not a real fish. Starfish such as sea urchins and sandbags have no backbones, so they will be a group of invertebrates. Fish have bones that make them a vertebrate. I got? The collection of menus are molluscs such as oysters, oysters, snails and so on. Starfish can be eaten by placing it on prey and penetrating its stomach through its mouth. Enzymes from stomach of starfish digest prey. The digested material enters the starfish stomach. Small creatures can swallow whole. Starfish occupies all kinds of habitat including tide pool, rocky coast, seaweed, seaweed bed and coral reef. Some starfish live on a beach that is 9,500 m (20,530 ft) deep.
