VS'is an assault that stunned researchers. According to a research revealed on Friday March 1 within the African Journal of Marine Science, relayed by BFMTV, an orca attacked a 2.5 meter lengthy white shark on June 18 in South Africa. While the orca's goal was not a shock, it was the truth that it attacked alone that stunned scientists.
According to them, an assault of this kind might be a primary, provided that orcas are accustomed to looking in teams. Indeed, often, such a confrontation with a white shark takes place in teams of two to 6 and may last as long as two hours. This time, it was in simply two minutes that the mammal killed its prey.
Primo Micarelli, a marine biologist on the Italian Center for Shark Studies and the University of Siena, remembers seeing, from his ship, the orca “carrying the liver of a white shark” earlier than his eyes. An “unforgettable” picture, in response to him.
Climate change “puts pressure on our oceans”
This occasion challenges “conventional cooperative hunting behaviors known in the region,” defined Alison Towner, lead creator of the research, who indicated that the rationale might be human actions: “Climate change and Industrial fishing places stress on our oceans. »
Scientists assume that the unprecedented assault by this orca is the results of stress linked to time spent looking close to the coast, in extremely populated areas. “I am increasingly concerned about the balance of coastal marine ecology,” warned Primo Micarelli.
