Movie 2 (Squid capture.mp4):

Video clips upon squid captures by female northern elephant seals. Clip 1: The seal fed on the squid Histioteuthis sp. (depth: 656 m). Clip 2: The seal fed on the squid Octopoteuthis sp. (depth: 415 m). Clip 3: The seal encountered the squid Taningia danae (at time 00:18; depth 662 m), but the squid escaped (00:21). After following the lights from the tentacles of the squid (00:26-00:34), and encountering with squid ink (00:39-00:49), the seal captured the squid (00:51), as indicated by the quick movements of the snout. In all video clips, supraorbital vibrissae of the equipped seal are visible at the right-hand side of the movies.
