Starfish is not actually a fish at all! There are several types of shapes of this nature’s creation: like Sugar starfish, white starfish, Crown of thorns, sunflower star, Bahamian etc. Actually, there are nearly 2000 kinds of sea stars!
We use to think that starfish has its five legs, but some of them have more, which radiate from an indistinct disk, like sunflower fish.
There are about 1,800 known living species of them, and they occur in all of the Earth’s oceans. People often buy starfishes for home aquarium.

(The common starfish is normally 10-30cm )

Starfish can change its color, can do a lot of fun things with ther legs, but! – they don’t have ears and nose…
Most of its life, starfish moves slowly across the ocean floor.
The next shocked fact: If a starfish is cut into pieces, each piece will grow into a whole starfish!

The next amazing fact:
Starfish are almost unique in the fact that, unlike most other animals, they do not have blood but instead use sea water to pump around their bodies!

And what surprised me more then other facts that, because of this ability to digest food outside of its body, the sea star is able to hunt prey that are much larger than its mouth.
Really, curious, bright monster. )
