Cirrothauma magna, also known as the big-eye jellyhead,[2] is a species of deep-sea cirrate octopus that has been found in the Indian, Atlantic, and Pacific oceans. It is known from four damaged specimens.[3] Their shells are somewhat saddle-shaped. C. magna is the sister taxon of Cirrothauma murrayi, but can be readily distinguished by having large and well developed eyes (whereas C. murrayi is near blind).[4]
Cirrothauma magna is likely the largest species of cirrate octopus, one female specimen measuring 1.7 m total length.[5] The animal has delicate, jelly-like flesh.[2]
