Impressive series of video clips from the scientists at Massey University and the University of Western Australia. Demonstrates conclusively the effectiveness of a hagfishes (snot-eel) defense mechanisms on a Kitefin Shark and a couple of greedy hapuka. Footage is shot off Great Barrier Island and at the Three Kings.
Excerpt from the original source: ”Hagfishes (Myxinidae) are a family of jawless marine pre-vertebrates. Those video images taken in New Zealand revealed that hagfishes are able to choke their would-be predators with gill-clogging slime.It also shows that hagfishes are actively preying on other fish in New Zealand waters.”
The video is part of a scientific paper describing this newly discovered behaviour which can be downloaded online at http://www.nature.com/srep/2011/111027/srep00131/full/srep00131.html
