Octopuses, Squids and Cuttlefish

The cephalopod mollusks are the most highly evolved and intelligent of all invertebrates. Many are capable of nearly instantaneous color changes that reflect their mood and/or aid in camouflage. They all possess arms and/or tentacles, and have the most highly developed eyes and nervous systems among the invertebrates. The giant squid is the largest of all invertebrates, and has the largest eye of any living animal.
