Magnapinna talismani

Magnapinna talismani is a species of bigfin squid known only from a single damaged specimen. It is characterised by small white nodules present on the ventral surface of its fins.

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 mm mantle length (ML) collected in the northern Atlantic Ocean, south of the Azores, at 34.76667°N, -36.18333°W. It was caught by an open bottom trawl at a depth of up to 3175 m. 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.
