Adelieledone polymorpha, or the Antarctic knobbed octopus, is a species of octopus found in the Antarctic.[3] It was first described by Guy Coburn Robson in 1930, based on specimens found in South Georgia.

Taxonomy

[edit]

Robson originally placed Adelieledone polymorpha in the genus Graneledone.[4] It was then placed in the genus Pareledone, but was moved to the genus Adelieledone in 2003.[5] Robson also split Adelieledone polymorpha into two varieties, oblonga and affinis; that distinction was removed in 2003 as it was likely a result of deformation and misclassification of specimens.[6]

Description

[edit]

Adelieledone polymorpha is of moderate size and robust,[7] with a mantle length of up to 60 millimeters, and a total length of up to 200 millimeters.[6]
