Blue-ringed octopuses carry a killer concoction called tetrodotoxin (TTX), a potent neurotoxin that can paralyze living ...

Octopuses have many amazing abilities and characteristics; they have huge brains and can solve puzzles; their ink can ...

These intelligent sea creatures have multiple brains — nine, to be exact. In addition to a central brain located between its eyes, an octopus has eight separate clusters of nerve cells, called ganglia ...

And the hundreds of suckers on each arm have over 10,000 chemotactile sensory receptors each, working with 500 million neurons to pick up that information and relay it throughout the nervous system.

But, unlike vertebrate organisms, the octopus’s nervous system is also decentralized, with around 350 million neurons, or 66 percent of it, located in its eight arms.

Scientists inspired by the octopus’s nervous system have developed a robot that can decide how to move or grip objects by sensing its environment.

Cuttlefish Cuttlefish, which are octopuses' and squids' cousins, possess a well-evolved nervous system with both large central brain and well-evolved ganglia in their arms.

Octopus arms move with incredible dexterity, bending, twisting, and curling with nearly infinite degrees of freedom. New research from the University of Chicago revealed that the nervous system ...

This provides each arm with a degree of autonomy, allowing an octopus to use some arms to perform one task while also carrying out another, entirely different activity with other arms.

The octopus nervous system is among the most unusual on Earth. Unlike in other intelligent animals, it's highly distributed, with a significant proportion of its 500 million-odd neurons spread ...
