A study done in 2019 showed that killer whales were very good at threatening creatures considered ocean spirits; So the throne “suddenly top of the table” of the sea should have only one owner.
The team of American scientists has just discovered that the great white shark (scientifically known as Carcharodon carcharias) will immediately swim away when seeing the presence of the killer whale (Orcinus orca).
“When confronted with killer whales, the white shark will immediately leave the favorite hunting grounds and avoid going elsewhere, even leaving for a year to return, even when the whale is close. he just swims across that water“, Oceanographer Salvador Jorgensen of the Monterey Bay Marine Park said.
The team gathered data from two sources: arrivals and departures of 165 great white sharks with geotagging between 2006 and 2017; In addition, there are 27 years of data on the number of killer whales, sharks and seals. The Point Blue Department of Conservation Science, based off the coast of San Francisco, gave the Jorgensen team valuable data.
The team also tracked four encounters between great white sharks and killer whales in a protected marine area in California, in order to match the data with those obtained.
Analysis and conclusion: every time killer whales appear in the area, every time, sharks quickly hide and hide until the next water season. Within minutes the sharks have turned the water to swim away, even when the killer whale just hovered in the water for less than an hour.
This shark’s action is beneficial for the northern sea seal (Mirounga angustirostris), which is a favorite dish of the great white shark.
“On average, we found about 40 seagulls being attacked by white sharks per water season“, Says researcher Scot Anderson. “After the killer whale appeared, there did not appear a case of attacking and destroying a target of the shark in this water.“.
Sharks don’t always avoid going very far. Sometimes, they only swim along the coast until they feel safe enough, where they are still close enough to reach the colony. Sometimes, they will swim straight out in the middle of the Pacific, to the water filled with white sharks, unofficially known as the White Shark Cafe.
The journey moves by time of the year of the shark, to the “cafe” and back to the familiar waters.
You also do not think that killer whales bully small sharks: there are large white sharks up to 5.5 meters long, which claim to be in every country they place their fins, still have to wrap up when you see. killer whales. Scientists have discovered many cases of killer whales hunting sharks in waters around the world. Although it is unclear exactly why, one can also speculate based on the bodies of white sharks washed ashore, carrying killer whale bites on the hips: these corpses have lost the fatty liver. , rich in vitamins.
Shark body washed ashore.
Small question: In theory, both the white shark and the killer whale are the top predators in the salt water, but will the great white shark teach its descendants that “avoiding (whales) whales is not bad Which “? Is that the story that is brought to the table every time the sharks sit and talk outside the White Shark Cafe?
Perhaps we cannot answer this question at this time. As with the relationship between the great white shark and the killer whale, more modern research and technology is needed to uncover the mystery.
