This breed of octopuses is very rare and is found in tropical and subtropical oceans. The reason why they are called blanket octopus is that their body structure is long and they have web-like arms connected to their dorsal. Female octopuses (2m) are longer in length as compared to the male octopuses (2.4cm).

The reason for the differences in size is because females have to keep the male octopuses’ detached arm inside them while mating to give birth to around 100,000 eggs.
