Did you know that marine scientists are trying to change the starfish’s name to sea star? They’ve decided to change it because the starfish is not actually a fish, it’s an echinoderm (related to sea urchins and sand dollars). In fact, the starfish doesn’t even have a brain or blood. Their nervous system is spread throughout their body and their “blood” is filtered sea water.
