How often do you come across a cannibal shark, much less capture one on camera?
Capturing a cannibal shark gulping down a smaller shark (still 3 feet long!) wasn’t on their minds when students of University of Delaware’s Ocean Exploration and Remote Sensing, Biogeography Lab were trying to retrieve tags from sharks they had tagged earlier. Scientists often tag wild animals including fish to get more information on their habits, environments and interaction with other animals.
These guys had dangled a piece of menhaden to bait one of those previously tagged sharks just as the shark season was starting off, when they ended up witnessing a huge and ferocious looking female sand tiger shark swallowing a 3 feet long smooth dogfish which had latched onto the bait! Considering how less we know about shark behaviour and the changing ocean environments, it isn’t surprising that the scientists are offering finders $100 for each recovered tag.
