A veined octopus eating a crab.. Unlike most other molluscs, all cephalopods are active predators (with the possible exceptions of the bigfin squid and vampire squid).Their need to locate and capture their prey has likely been the driving evolutionary force behind the development of their intelligence.
[10] Octopus eyes, too, look and work much like those of vertebrates; but there, Baer remarks, the similarities end. Cephalopods are "immensely foreign", with "a distributed sense of self" and a "lived reality" quite unlike human consciousness, a feature that, he notes, Godfrey-Smith calls "the most difficult aspect of octopus experience to ...
They have a seemingly simple brain, not the large complex brains of octopus, cuttlefish and squid, and had long been assumed to lack intelligence.

The octopus central brain contains 40 to 45 million cells. The brain-to-body mass ratio of the octopus is the highest of all the invertebrates and larger than that of most fish and reptiles (i.e. vertebrates). However, scientists have noted that brain size is not necessarily related to the complexity of its function.
The squid Sepioteuthis sepioidea has been documented changing its appearance to appear as the non threatening herbivorous parrotfish to approach unaware prey. The octopus Thaumoctopus mimicus is known to mimic a number of different venomous organisms it cohabitates with to deter predators. [46]
