Alien-Like Octopus Transforms Into Huge Balloon

An octopus transforms into a huge balloon in footage from an expedition more than 5,000 feet below the water’s surface.

The expedition took place at the Pacific Remote Islands Marine National Monument, one of the world’s largest marine conservation areas.

The Expedition

The octopus, estimated to be 4,3 feet long, billows up like a huge balloon.

The Transformation

It expands and contracts, showcasing its remarkable ability to shapeshift.

As seen here, when threatened, some octopuses can inflate their bodies to appear larger and more intimidating.

Octopuses are famous for their remarkable ability to shapeshift, change color and texture, and even alter their size.

Thanks to specialized cells in their skin, chromatophores, pigment-filled cells that can expand or contract, allow the octopus to change its color.

Changing Color

Their skin contains muscular hydrostats, structures similar to the human tongue, that can change shape.

Changing Texture

Octopuses are boneless creatures, which allows them to change their shape dramatically and they can squeeze their entire body through tiny openings.

Changing Shape

Some octopuses, like the mimic octopus, can imitate the appearance and behavior of more dangerous animals. 

Octopuses use color changes to communicate, especially during mating rituals. Bright colors can signal readiness to mate.


By changing their appearance to match the seabed or coral reefs, octopuses can sneak up on their prey undetected.
