Octopuses are known to be the most intelligent species among all invertebrates. They are excellent at camouflaging and mimicking. They have a super-flexible body that helps them radically alter their shape. They come in diverse shapes, sizes, and colors and have a highly complex nervous system and exceptional eyesight.
Cirrothauma magna is the rarest octopus species on this list. Only four specimens of this rare octopus have ever been captured. Thus, available information on this species is fairly limited. It does not even have a common name.
An adult Cirrothauma magna has three types of suckers. The suckers nearest to its mouth are small and cylindrical with thick stout stalks and are separated by 1 cm. The following suckers have long stalks and small openings, and the gap between them is 2-3 cm. The distal suckers (sucker number 30+) are muscular with a bowl or barrel-shaped fleshy base.
