Seastar

Seastar

The starfish feeds on oysters and clams, the 2 stomachs of the starfish helping with the digestion of complex organism. The starfish uses one stomach to begin the digestion of the food, and the other stomach to expand outwards and engulf their prey. Starfish can be found in the oceans all around the world.They have bony, calcified skin, which protects them from most predators, and many wear striking colors that camouflage them or scare off potential attackers. Purely marine animals, there are no freshwater sea stars, and only a few live in brackish water.Beyond their distinctive shape, sea stars are famous for their ability to regenerate limbs, and in some cases, entire bodies. They accomplish this by housing most or all of their vital organs in their arms. Some require the central body to be intact to regenerate,
