While swimming across the ocean away from human eyes, a lot of shark life is a mystery. But if you look closely, you can find evidence about what they have experienced – in particular, through injuries, wounds and scars.

In a new study, published in the magazine Borders in marine scienceThe researchers suggested a system to classify the reasons that cause scars on the great white shark fish (Carcharodon Carchaias).

The author of the study says: “The scars and wounds that were seen on sharks tell us about their interactions with each other, their environment, their prey and humans.” Scott Anderson From the white shark project in California.

“Many scars are sufficiently distinctive so that they can be easily classified, such as the CookieCTER shark (Isistius BrazilDecide the bite of a complete circle or the crescent moon mark when it does not remove the bite. “

The white shark team participated in California video From a 16 -feelty white shark with an unusual scar on top of her head. While the shark swims towards the camera, it becomes a perfect circle visible on its head, such as the dolphin hole. This is the distinctive ingredients of the completely lost circular pill that show that they have been out of the CookieCuter shark.

Anderson says: “Cookiecster wounds can tell us that white sharks get these signs during the” outer stage “from deporting them because that is when they interfere with CookieCuter.”

Other types of scars may indicate boats, defense wounds, or scraping of rocks. You can tell us whether the shark is mating. Females may have “light impressions” of other sharks bites on their heads and chests from the intercourse meeting.

He says: “In many types of sharks, males must bite the female in order to stick to it on the movement.” By the time his team notes this “bites that take place”, they are “always or completely healing”, and Anderson says, indicating that white sharks are mating outside – which gives scientists another idea about where and how great eggs multiply.

Anderson adds: “It is a set of evidence and a piece of mystery to try to determine a place and when the white shark mates, where we still do not know for sure,” Anderson added.

But in order to be able to explain these clues – written in the scars on the shark body – we need to be able to determine how the injury occurs. For example, the study indicates that a “pattern of divergent points” shows the place where the parasite that was connected to the animal is used, “a series of parallel cuts with spacing” is a sign of the boat fan, and it can be a “white rope” of tangling in fishing equipment.

The new paper proposes a “systematic classification system” to help scientists determine the source of different types of scars, wounds and injuries.

Anderson says this information helps us to learn more about these wonderful animals: “It is another piece of mystery that tells the story of what these white sharks face.”
