Furthermore, when Pearson went back to see if the shark was there the following day, it was not. “That’s a fucking white shark,” Pearson said in the video. The Great White Shark is a large lamniform shark that can swim in water as shallow as 3 feet deep. The tags are designed to eventually fall off the shark and float to the surface of the water where the stored data gets transmitted to satellite receivers.

Shark fin soup to blame for blue shark decline, Juliet Eilperin on the hidden world of sharks. ROD behavior was the most common among male sharks during the months of May, June and July. Bottom line: A new analysis of behavioral data collected from tagged great white sharks suggests that some sharks may be visiting an open area of the Pacific Ocean known as the White Shark Café to participate in a lek-like mating system. But while the shark may have escaped the shallows and Pearson may have escaped a potential great white bite, he and his friend did not leave the water unharmed.

The Monterey Bay Aquarium Foundation and the Sloan, Moore and Packard Foundation provided funding for the research. Now, a new analysis of behavioral data collected from tagged great white sharks suggests that some sharks may be visiting the Café to participate in a lek-like mating system. In general, the mating system of white sharks remains somewhat of a mystery because these species are very difficult to observe in the vast expanse of the open ocean. But it was actually there for another reason. The scientists believe that this type of behavior was associated with foraging. To better understand how great white sharks are using open ocean habitat, scientists attached pop-up archival transmitting (PAT) tags on numerous white sharks (Chacharodon carcharias) and tracked their behavior.

Leading that list is the tiger shark, which the U.S. Navy Diver's Manual has always rated as being equally as dangerous as the great white. Leks are used for reproduction by many migratory species including birds, mammals, reptiles, insects and fish.
