Order Octopoda: Suborder Cirrata

<< Cephalopod Species
Opisthoteuthis agassizii
Little is known about the finned octopuses in the suborder Cirrata as they are found in the deep sea. Voss (1988) describes them as "soft-bodied, semigelatinous animals with a pair of small to large fins, a deep and sometimes complicated web and a relatively large, single internal shell." Cirrate octopuses lay large eggs which may indicate that the hatchlings are well developed and adult-like in behavior (Voss 1988).

A thank you goes to Mike Vecchione at the National Museum of Natural History for providing the above picture of an Opisthoteuthis agassizii. The photograph was taken from a sub at a depth of 586 m and a bottom temperature of 6.6 degrees Celcius (Vecchione and Roper, 1991).
