Cirrata

Suborder Cirrata (Cirromorpha) Holocene; soft-bodied, deep-webbed forms with cirri on arms and small to large paddle-shaped fins; primarily deep-sea. Suborder Incirrata (common octopus) Holocene; compact, saccular to round bodied, finless forms with muscular, contractile arms; somewhat secretive; pelagic to deep-sea and shallow

The Cirrata, which have reduced musculature and radula, indicating reduced activity and masticatory power, probably feed on bottom dwellers or small plankton.
