Atlantic Pygmy Octopus

One of the smallest octopus species, fully grown, this cephalopod reaches a mantle length of 4.5 cm (1.8 in) with arms up to 9 cm (3.5 in) long.

It often seeks shelter from predators in empty clamshells, beer cans or small openings, pulling the opening closed with its arms, combining sand and gravel to form a lid.

Blue Ring Octopus

Despite their small size, 12 to 20 cm (5 to 8 in), and relatively docile nature, they are dangerous to humans if provoked and handled, because their venom contains tetrodotoxin, a neurotoxin powerful enough to kill humans.

Their primary habitat is around southern New South Wales, South Australia, and northern Western Australia.

Caribbean Reef Octopus

The Caribbean Reef Octopus

A shape-shifter, capable of changing color and texture to blend into its surroundings using specialised skin cells known as chromatophores. It can change from crimson to green, and bumpy to smooth, making it highly elusive.

Despite its name, it is found in tropical regions around the world, in the warm waters around coral reef environments and grassy and rocky sea beds.

California Two-Spot Octopus

Due to their friendly temperament and relative hardiness, they are considered by most experts to make the best pet octopus.

East Pacific Red Octopus

The East Pacific Red Octopus

The most commonly occurring shallow-water octopus on much of the North American West Coast its range extends from the southern Gulf of California at least to the Gulf of Alaska.

It is also known as the ruby octopus, a preferred common name due to the abundance of octopus species colloquially known as red octopus.
