What defines this group — Cephalopods
Octopuses, cuttlefish, squid and nautiluses: molluscs that became the most intelligent invertebrates.
- Eight arms — ten in cuttlefish and squid — set around a horny beak.
- Skin cells called chromatophores change colour and texture in a fraction of a second.
- Three hearts, and blue blood that carries oxygen with copper rather than iron.
