Unique facts about shark wild life that are rarely known

A study reveals the surprising social life of sharks. Apparently, some sharks have a spirit of solidarity.
The study focused on the social behavior of 41 reef sharks around Palmyra Atoll, 1,600 km southwest of Hawaii. Shark life is monitored using acoustic transmitters to track them and cameras for clarity on their attractions.Sharks form stable social communities over time. The same individuals continued to carry out joint activities during the four years of the study.Sharks are extraordinary animals and are still quite misunderstood," said Florida International University marine biologist Yannis Papastamatiou.

The reef shark is medium in size, reaching about two meters in length. Its social life has similarities with certain birds and mammals in terms of stability over time. However, they differ in a number of ways, including nesting, mating, and sounding.

The researchers suspect that the sharks flock together to ensure that the various individuals of them find prey. Sharks can keep their company together for several years.

"For some time, we have known that sharks are able to recognize specific partners and groups and have social preferences," said marine biologist and study co-author David Jacoby.

"Our research reveals, for the first time, that they (sharks) are actually able to maintain friendships for several years," Jacoby added.

However, according to Papastamatiou, this kind of group life is not always practiced by sharks. There are also some sharks that live alone.

"I like to talk about their 'secret life', not because they want to keep it a secret, but lately we are developing tools to start seeing and understanding their social life," Papastamatiou said.

"Not all sharks are social and some tend to be solitary," he added.
