Researchers from the University of Hawaii have successfully mapped out behavioral patterns of different shark species by attaching video cameras on them.

The video showed that Galapagos and hammer head sharks swim together to protect themselves from the predator sandbar sharks.

"So by being in a school of sharks you decrease your odds of being the one that's being caught when a big tiger shark comes through and wants to eat you," Carl Meyer, researcher with the University of Hawaii's Institute of Marine Biology told KITV News.

Meyer also explained that these shark species tend to swim together while roaming around but when they ascend towards higher levels of the water; their movements resemble a "tornado of sharks." Once they have finished hunting as a group, each of the tiger sharks will break off and proceed to do things by itself.

Scientists dubbed this activity as "Sharknado." Meyer said there was no observed frenzy eating but he is certain that there will be soon.

The video proved that these 12-foot tiger's sharks are truly feared by other species. The researchers noted that other species are evasive of the tiger sharks and no fish dare to come close to a school of such sharks.

Other than that, scientists were given an opportunity to see sharks' digestive behavior through a four-inch plastic device. The device is an electronic pill that is ingested and then regurgitated after a period of time.

These devices will then float into the surface and will allow scientists to isolate the data to find out the eating patterns of tiger sharks. Data from these pills include the frequency of meals and how much these sharks are eating.

Through video-tagging, the scientists are on their way to fully understand why recent attacks occurred. But definitely, the tiger shark's behavior is that of a predator's.
