A female Blanket Octopus might get to about a meter or 2 (3.3 to 6.6 feet) in length, but her first 2 pairs of legs are extra specially long. Attached to them is a huge span of webbing that is normally hidden away.In times of need, this drapery is unfurled, spread out and left to billow in the water. This makes her look far larger and more threatening than she actually is, hopefully scaring off any predators. If it doesn’t seem to be working so well, bits of her blanket can even detach from the rest to act as a decoy.

Blanket Octopus are immune to the stings of the Portuguese Man o’ War. They can rip off a few of the Man o’ War’s tentacles and wield them like whips. Poisonous, stinging whips.
