According to my twitter friends, seastars are the new name for star fish.
Mostly as seastars are not really fish.
Marine scientists have undertaken the difficult task of replacing the beloved starfish’s common name with sea star because, well, the starfish is not a fish. It’s an echinoderm, closely related to sea urchins and sand dollars.
here is some other facts they collected.
the sea star uses sea water as blood... a true marine creature!
If a starfish is chopped into pieces, each piece can grow a whole new starfish.
Starfish can have four or more arms, some have 12, but most have 5 arms.
Starfish do not have brains.
Starfish’s body has no blood.
Blind? Not Quite
Starfish are not completely blind, even though they do not have eyes. Starfish sense light and shapes through an eyespot (an organ sensitive to light) located at the tip of their arms.
