Do Cuttlefish Have Three Hearts?

Yes! Like their octopus and squid cousins, cuttlefish have three hearts pumping blue blood!

• Two hearts pump blood to their gills to get oxygen.

• The third heart pumps blood to the rest of their body.

• Their blood is blue instead of red because it contains copper instead of iron.

• The main heart stops beating when they swim, which is why they prefer crawling.

How Long Do Cuttlefish Live?

Cuttlefish have relatively short lifespans compared to many other sea creatures.

• They grow very quickly and reach adult size within their first year.

• Female cuttlefish often die after laying eggs, having used all their energy for reproduction.

• They don't attack people and prefer to hide or escape.

• The flamboyant cuttlefish is the only poisonous species—its bright colors warn predators to stay away.
