From Wikipedia, the free encyclopedia
Cirrata is a suborder of the order Octopoda. Most lay people are unaware of this order and even biologists do not know much about it. Cirrata octopuses have a small, internal shell and two fins on their head, while their sister suborder, the Incirrata has neither.
The suborder is named for small cilia-like strands on the arms of the octopus. There is a pair of cirri for each sucker. These are thought to play some role in feeding, perhaps by creating currents of water that help bring food closer to the beak.
