No living creature can out-bend an octopus

Octopuses have the most flexible arms in the natural world, according to a new paper in Scientific Reports.

A team of researchers filmed 10 octopuses over several months to capture more than 16,000 arm movements.

These movements were broken down into four categories.

Bending and twisting

Elongating

And shortening

All eight arms of the octopus can make these movements in any orientation — left, right, up, or down.

The octopuses examined could combine movements, such as twisting while elongating or bending.

Even the researchers, who are very familiar with octopuses already, were surprised at the animal's flexibility.

Learning more about the octopus's intricate motor control could inform the field of soft robotics, the researchers said.
