TRIBUN-BALI.COM- Sharks are known as ferocious predators, which are also the largest predators in the ocean, especially the large white sharks.
It turns out, however, that large white sharks may also fear the existence of other animals, according to a recent study.
The Monterey Bay Aquarium Team found that large white sharks (Carcharodon carcharias) would move away when they discovered the presence of a killer whale (Orcinus orca).
"When there is a whale assault, the white shark will immediately leave the hunt and will not return again in a year, even though the whale simply passes," said Salvador Jorgensen, a marine ecologist at the Monterey Bay aquarium. , Thursday (4/18/2019).
The study was conducted in a population of large white sharks and killer whales in the Greater Farallones National Reserve, California, USA.
Based on observations and data analysis, whenever an assassin is captured in a given area, sharks will escape quickly and will not return to this spot until next season, although whales appear less than an hour.
However, sharks do not escape so far, but only move to surrounding coastal areas to hunt sea elephants (Mirounga angustrostrous). But sometimes shark colonies can be found in the middle of the Pacific Ocean.
This is good news for the native population of the sea elephants.
"After the killers' whales appeared, no shark observations were recorded and no elephants died," said Scott Anderson, another researcher who participated in the study.
There are two types of oxen, namely moving active whales and whales that settle in certain places.
