Editing Grimpoteuthis (section)

==Movement, characteristics, and food supply==
Observations of animals in the Atlantic reveal that ''Grimpoteuthis'' often rest on the seafloor with the arms and web spread out and uses its arms to slowly crawl along the seafloor. When disturbed, the webbing and arms are contracted to propel the animal off the seafloor and using the mantle fins for rapid locomotion.<ref name="Villnva-Sgnzc-Guerra-1997">{{Cite journal |last1=Villanueva |first1=R. |last2=Segonzac |first2=M. |last3=Guerra |first3=A. |date=July 1997 |title=Locomotion modes of deep-sea cirrate octopods (Cephalopoda) based on observations from video recordings on the Mid-Atlantic Ridge |journal=Marine Biology |volume=129 |issue=1 |pages=113–122 |doi=10.1007/s002270050152 |bibcode=1997MarBi.129..113V |s2cid=85848021}}</ref> 

The cushiony cartilage that can be found in the proximal position of the fin of ''Grimpoteuthis'' is responsible for acting as a support for the thick muscles that allow for rapid locomotion. 

Although it has been suggested that species of ''Grimpoteuthis'' are capable of [[Aquatic locomotion|jet-propulsion]] (while swimming using the fins), this has since been deemed unlikely.<ref name=Villnva-Sgnzc-Guerra-1997/> 

Feeding behavior has not been directly observed in ''Grimpoteuthis'', but presumably is similar to ''[[Opisthoteuthis]]'' which can trap small prey items in the webbing (either by enclosing the prey in the arm webbing or between the webbing and the seafloor) and then use the cirri (fingerlike projections along the arms) to move food to the mouth. Known prey items (from dissected animals) include benthic [[polychaetes]], [[benthopelagic]] [[copepods]], [[amphipods]] and [[isopods]].<ref name=Collns-Vllnva-2006/>
