A small Magnapinna squid (62 mm DML) was seen in a horizontal position, parallel to and just above the seafloor. Its proximal arms/tentacles were spread outwards at an almost 90 degree angle to the body axis (causing the mantle and proximal arms/tentacles to appear as a cross-like shape in the image), and its distal arm/tentacle filaments streamed posteriorly, perpendicular to the proximal arms/tentacles and parallel to the seafloor (seen here as fine lines running diagonally from the squid to the bottom right of the image). The shadow of the Magnapinna squid can be seen below, duplicating the described posture. This image is an enlarged and cropped portion of a towed camera still image and light levels have been adjusted for clarity.
