Sharks get bigger and angrier after meeting people.

From frequent contact with people, tiger sharks become larger and more aggressive. These conclusions were reached by Brazilian and American scientists who observed fish on the tourist Tiger Beach in the Bahamas. The sea in this place is shallow and clean, so sharks often swim there. Tour operators specially feed them to make diving customers more fun. It turned out that the sharks most often appearing on Tiger Beach were larger than other sharks, their hormone levels were 3-16 times higher, and their blood contained more nutrients. That is, mass tourism is likely to have a positive effect on the health of sharks. At the same time, the aggressiveness of fish may be due to competition for food. Most often, adult females swam up to people, many of them were pregnant. Juveniles stayed away from Tiger Beach.
