YouTube Description
as posted by the channelEight male elephant seals were observed for a year repeatedly hunting for prey near an acoustic imaging sonar. The Ocean Networks Canada had a cabled video-observatory at the Barkley Canyon Node off the coast of British Columbia to study the effects of light and bait on deep-sea fish and invertebrate. While observing the video footage, researchers noticed these elephant seals continuously returning. The scientists theorize that the seals associated the sound of the sonar with an abundance of prey in the area, which is known as a "dinner bell" effect.
