The size and structure of the octopus brain varies according to the habits and habitats of octopus. Octopus have one of the largest brains of invertebrates, with some species having more than half a ...

Cephalopods – including octopuses, cuttlefish and squid – possess one of the most sophisticated neural systems among invertebrates, which supports a wide array of complex behaviours. Their neural ...

The octopus is an exceptional organism with an extremely complex brain and cognitive abilities that are unique among invertebrates. So much so that in some ways it has more in common with vertebrates ...

Scientists believe they have discovered some key information about the octopus' brain. We've known for centuries that octopuses are smarter than your everyday invertebrates. However, we never really ...

The unique brainpower of octopuses—known for their intelligence and Houdini-like escapes—has been revealed by University of Queensland researchers. Dr. Wen-Sung Chung from UQ's Queensland Brain ...

Among the smartest animals on Earth, octopuses are unique for being utterly weird in their evolutionary path to developing those smarts. Philosopher Peter Godfrey-Smith has called the octopus the ...

Some scientists have already made the argument that octopuses might be aliens. While the claim seems a bit out of this world, new research into their brains continues to show just how alien the ...

A video shows an octopus appearing to wake up from sleep in distress. The behaviour looked similar to waking up from a nightmare, scientists said. The findings raise questions about the possibility of ...
