The Blanket Octopus is a fascinating animal with a beautiful defense mechanism. The males have an almost irrelevant existence because they are only a few centimeters long and die shortly after mating. They store sperm in a specially modified arm which detaches itself during mating and crawls into the mantle of the female to fertilize her eggs.
Females, however, can grow to over 2 meters in length and when they feel threatened, a set of arms tucked within their bodies unfurls a spectacular scarf-like net that connects the dorsal and dorsolateral arms. When spread, this webbing makes the animal look much bigger than what it really is, scaring potential predators.
