Gorgeous new video footage exhibits nice white sharks looking seals — all from the large predator’s perspective. The sharks have been fitted with video cameras that recorded some stunning behaviors.

The footage revealed that some nice white sharks (Carcharodon carcharias) spent a part of their days swimming by way of kelp forests, the place cape fur seals (Arctocephalus pusillus) frolicked. This discovering, scientists say, is sudden on two fronts.

For starters, earlier research confirmed that nice whites often hunt alongside the perimeters of kelp forests at nightfall and daybreak, when the solar is not too vivid, so the predators can ambush seals arriving and leaving the refuge. So, it is uncommon that these sharks hunted within the kelp forest throughout daytime, the researchers mentioned. And second, it was beforehand assumed that kelp forests have been inaccessible to those massive predators, the researchers wrote within the research. [In Photos: Great White Sharks Attack]

The scientists did the experiment close to a cape fur seal colony on Geyser Rock within the Dyer Island Marine Reserve off the coast of South Africa in Might 2014. They lured the eight nice whites with fish chum after which hooked up video cameras to the sharks’ backs. After recording a median of 28 hours of daytime footage per shark, the cameras indifferent from the animals, permitting the researchers to gather and evaluate the recordings.

Not one of the footage confirmed the sharks efficiently killing a seal (which was disappointing to the researchers, and certain the sharks too). However footage from one shark confirmed 10 interactions with seals. These furry mammals swam round in teams of 1 to a few people and “responded to the presence of the shark by blowing bubbles, swimming deeper into kelp or hunkering to the seafloor,” the researchers wrote within the research.

Although the sharks did not catch any seals, kelp forests should be helpful looking grounds for sharks, the researchers mentioned. Way more footage is required earlier than scientists can say both means. Furthermore, the scientists mentioned they have been impressed with the sharks’ agility within the kelp forests.

The research is the primary of its variety to point out that nice white sharks usually swim by way of kelp forests in quest of prey. It was printed on-line yesterday (April three) within the journal Biology Letters.
