Suborders
Cirrina Incirrina

Octopods are put into two suborders. One, the Incirrina, is composed of the well-known Octopus of rocky shores and coral reefs and its relatives. The other suborder, the Cirrina, contains octopods whose tentacles are linked by an umbrella-like mantle, so their activity is rather different from the common octopus.
