With their innovative robot design, the researchers were able to closely replicate the swimming pattern observed in octopuses ...

The graphs represent angular speed of the arms over time. These graphs can indicate synchronous or asynchronous movement patterns between arms, which indicates when arms are receiving a common ...

Blanket octopus pairs are some of the undersea world ... not growing. Mating happens at arm’s length for the four species of these cephalopods. The tiny male detaches its hectocotylus ...

A flexible robotic arm mimics an elephant's trunk, twisting and stiffening to perform tasks, offering safer alternatives to rigid robots.

Each group creates their own octopus arm-waving pattern. Shoals of fish, shipwreck shapes and a hungry shark! Same groups of four travel closely through the spaces together with small, quick steps ...

"Until now, we didn't know an octopus could arm itself like this ... It displays a typical colour pattern with dark branch-like lines, usually with a yellow syphon and white suckers.

who has studied octopus behaviour, believes that these interactions are actually “high fives” – arm-slaps that help octopuses recognise each other. Octopuses can change colour and pattern.
