Digging in! Incredible moment sand octopus uses its tentacles to burrow into the ocean floor and hide from predators

  • The sand octopus wriggles its tentacles to create a 20-centimeter burrow below
  • The octopus uses a funnel to shoot jets of water into the sand to create a hole 
  • It submerges into the ocean floor and disappears in Port Phillip Bay, Australia 

A sand octopus has been filmed wriggling its tentacles to create a burrow into the ocean floor and disappearing as a disguise technique to hide from its predators.

Marine biologist Jules Casey stumbled across the octopus while diving in Port Phillip Bay, Australia. 

Footage shows the animal moving across the seabed before curling its tentacles and burying itself below.

The sand octopus eventually disappears as it submerges into the sand.

This octopus, native to the waters around the Great Australian Bight and Tasmania, uses unique techniques to hide from predators.

It begins by using its siphon or funnel to shoot jets of water into the sand and then digs into the hole with its arms. 

The sand octopus then constructs a 20-centimetre burrow and reaches two arms to the surface as a ‘chimney’ to breathe through. 

The animal is thought to lack colour changing organs found in other octopus species and uses this technique this disguise technique instead

It will secrete a kind of mucus to allow the walls of the burrow to to remain in place

It will secrete a kind of mucus to allow the walls to remain in place and pull in its ventilating tentacles to appear completely buried. 

The southern sand octopus is thought to lack colour changing organs, known as chromatophores, which other octopus species use to camouflage themselves from predators. 

It instead uses this digging technique throughout the day and resurfaces at night.
