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.
Cephalopods like the octopus or giant squid represent "an independent experiment in the evolution of large brains and complex behaviour" predicated on the same neural systems as our closer mammalian relatives. Neither language nor a worldview is needed for a measure of intelligence in these "other minds" that share planet Earth. [2]
The terrifyingly powerful Gorgon of Greek mythology may have been inspired by the octopus or squid, the octopus's body representing the severed head of Medusa, the beak as the protruding tongue and fangs, and its tentacles as the snakes.

The more scientists study octopuses, the more we learn how fascinating these creatures really are. Octopuses are incredibly intelligent, displaying all kinds of amazing behavior like completing ...
Octopus: 500,000,000 [52] Western tree hyrax: 505,000,000 [43] Eurasian pygmy owl: 533,263,000 [34] ... Proxies for animal intelligence have varied over the centuries ...
Like many creatures living in the deep ocean, the strawberry squid can light itself up using bioluminescence. The squid floats along the water upside down with one eye aimed at the ocean floor and ...
Cuttlefish, like other cephalopods, have sophisticated eyes. The organogenesis and the final structure of the cephalopod eye fundamentally differ from those of vertebrates, such as humans. [20] Superficial similarities between cephalopod and vertebrate eyes are thought to be examples of convergent evolution. The cuttlefish pupil is a smoothly ...
Scientists have discovered what may be a completely new species of octopus-- and it's absolutely adorable.. On February 27th, the National Oceanic and Atmospheric Administration launched an ...
