Starfish are very beautiful water creatures. But besides its beauty, this animal has lots of surprises. This animal has no brain, but has eyes on its feet. Does not have blood, but can digest food outside his body.
Starfish are quite complex and different animals. They have no brain and no blood. Blood in an animal’s body is usually used to carry nutrients and oxygen throughout the body.
Because they do not have blood, starfish pump nutrients, oxygen, and other essential liquids throughout the body by using sea water which is distributed using a system known as the water vascular system. Throughout the body of the starfish there are canals filled with sea water that move through complex systems.
The body of the starfish is still a mystery because we still do not understand the whole working system. Research on the bodies of other stars is still one of the most interesting biological topics on earth.
