Greetings friends of steemit...
Today I will be talking about of the Sea stars.
FACT BOMB "Sea Stars"
It is a type of aquatic animal that has a great beauty, they are not fish, they are echinoderms, like sea urchins and sea cucumbers. At present there are more than 2000 species in which their colors, shapes and sizes vary.
¿Did you know that starfish do not have blood and that they have an eye at the end of each arm?
Starfish do not have blood, but they have a vascular system that allows seawater to be pumped into their food pipe. Their vision is not as clear as that of a human being, but they are able to detect light and move in darkness.
Another curious fact is that not all starfish have 5 arms, there are some species that have many more arms..
