Grimpoteuthis megaptera is a species of octopus known from five specimens, collected by Addison Emery Verrill. Between two and three of these specimens may belong to different species.[1]
Grimpoteuthis megaptera lives in the Atlantic Ocean off of Martha's Vineyard in the United States. It was found 4,600 meters deep.
Its full length reaches 107 millimeters.[2] Its eyes are small, as are its suckers and cirri.
The octopus' arms and web, when viewed orally, are brown. G. megaptera has yellow suckers and a blue-white mantle and fins. The mantle is spotted with irregular brown-purple markings.
