Credit to NOC and Deepscape.org: Coarse rocky ground with cirrate octopus (Cephalopod) above the seabed taken at 1126m in the Faroe-Shetland Channel. Others great images can be viewed by searching around their image bank.
The Cirrata contains about 40 species many of which are poorly known and of uncertain status…One of the most distinctive features of this group and the feature from which it derives its name, is the presence of cirri. The oral view of the arms and web of a cirrate below barely shows the cirri lining the arms but the insert show the cirri clearly. The cirri are the long, slender, muscular papillae lining the arm. The exact function of the cirri is unknown but they are thought to play a role in feeding.
