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 ...
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.
They have a seemingly simple brain, not the large complex brains of octopus, cuttlefish and squid, and had long been assumed to lack intelligence. But the cephalopod nervous system is quite different from that of other animals, and recent experiments have shown not only memory, but a changing response to the same event over time.
The human brain contains 86 billion neurons, with 16 billion neurons in the cerebral cortex. [ 2 ] [ 1 ] Neuron counts constitute an important source of insight on the topic of neuroscience and intelligence : the question of how the evolution of a set of components and parameters (~10 11 neurons, ~10 14 synapses) of a complex system leads to ...
The octopus was very pale, which McKay indicated was a symptom of dying from lack of oxygen. She carefully moved the hand-sized creature into a full tide pool, where she filmed it heavily ...
