It is the first described species of Magnapinna, although it was not recognized as a member of the genus until over a century later.

Description

The holotype of M. talismani is a specimen of 61-millimetre (2.4 in) mantle length (ML) collected in the northern Atlantic Ocean, south of the Azores, at 34°46′N 36°11′W. It was caught by an open bottom trawl at a depth of up to 3,175 m (10,420 ft). The capture location of this specimen is very near to that of the as-yet undescribed Magnapinna sp. B.

Taxonomy

M. talismani was originally placed in the genus Chiroteuthopsis, which is now considered a junior synonym of Mastigoteuthis. Mastigoteuthis talismani was subsequently placed in the genus Magnapinna by Michael Vecchione and Richard E. Young in 2006.
