What are the difference between starfishes and other fishes?

Starfish is a sea-urchin type of fish. Starfishes have many arms. Most of them have a central disk with five arms. Some of them also have twenty arms. These arms consist with tube feet. These tubes are related to an internal network of canals which goes through the starfish. The flowing stream through the network helps their tube to play a vital role like tiny sucking structure. Starfishes move on and get food using their hollow tube. They use their sucking feet and fold their arms together around a shell-fish to catch them.

The most interestingly unusual thing happens when their stomach stretches out of its body through their mouth and enters the shell-fish. After entering inside the shell, they start digesting the soft body of the clam by sucking into them.

Basically, a starfish can have a dozen clams a day. Because of that the crews on fishing boats always try to find out starfish. If they find it, they chop up it and send back in the ocean. But any places that had the part of the central disk grew into new one. Recently, it has been discovered that starfish can regenerate itself. SO, there is no way to kill it without drying. Actually, among all of the fishes, starfish is too much strange in nature.
