Magnapinna squids3/12/2023 Magnapinnid species are characterised by unique brachial morphology amongst all known cephalopods: the thicker regions of the arms and tentacles are often held at nearly right angles to the body axis and the long, slender portions of the arms and tentacles that trail the squid are nearly parallel to the body axis. (2001) described the occurrence of a large, strange squid recorded only by submersible or ROV observations in the Atlantic, Indian and Pacific Oceans. C ( Vecchione and Young 1998, Vecchione and Young 2006, Vecchione and Young 2016). talismani (Fischer & Joubin, 1907), Magnapinna sp. The poorly known deep-sea family Magnapinnidae, where only eleven specimens are known and deposited in collections worldwide, is presently understood to comprise five species: Magnapinna pacifica Vecchione & Young, 1998, M. The individuals exhibited characteristics of fully developed animals: one specimen had its complete arm arrangement with all its filaments, the other specimen lacked the filament on one arm. The size of the specimens, estimated through comparison with the riser (set of tubes that connect the well with the drilling unit) is of approximately 200 mm mantle length fin width 200 mm and a total length of ca. A review of the videos however, confirmed the family and genus (Michael Vecchione, Smithsonian Institute, Washington DC, personal communication). This is a common problem with photographic identification of invertebrates. It was thus not possible to get confirmation of the species. Unfortunately, the species cannot be determined without close examination of some details of the arm and tentacle suckers and these details were not possible to see with the videos provided by the ROV in the two sightings. 1 a, b, c) they were identified as members of the genus Magnapinna Vecchione and Young, 1998 ( Magnapinnidae Vecchione & Young, 1998) ( Vecchione et al. The second sighting (1 minute) was at the Gorgon 1 well ( 9☂5'59,282"N 76☄4'54,110"W) on 14 April 2017 (09:15 am) at 2,294.20 m depth.Īccording to the morphology of the specimens ( Fig. During routine inspection of exploratory wells by a Remotely Operated Vehicle (ROV) approximately 57 km off Arboletes and 67.1 km off Punta Broqueles (Moñitos, Cordoba), Colombian coast, two individuals of an uncommon deep-sea squid were observed in different locations.
