Star fish which are known as sea stars are a type of aquatic organisms found on sea beds. An usual starfish has a central disc and five arms but there are also some types which has more than five arms. They are widely grown in domestic aquariums as pet as they look pretty with their vibrant colours and unique form.
They primarily feed on clams and oysters and also some snails. There are over thousands of starfish species and are found all over the world oceans. An amazing fact about sea stars is that they can regenerate the lost arm and also they don’t have blood and brain.
