DID YOU KNOW? 💭


Starfish have no brains or blood.

Starfish don’t actually have a brain, or even blood! In fact, they use filtered sea water to pump nutrients through their nervous system instead.

In fact, despite their name, they are not related to fish at all. Perhaps surprisingly, Starfish actually belong to the group of marine invertebrates which also include sea cucumber, sea urchin and sand dollar!

The average lifespan of a Starfish is an impressive 35 years. Usually, large Starfish species tend to live longer than their smaller counterparts.
