The blue whale dives into the eclipse to change the side

when looking for food in shallow water, the blue whale dives to the left.

"right-handed" blue whale shows "right-handed" flexible behavior. This shocked scientists who studied the eating habits of the giant creature.
like many other animals, blue whales exhibit sideways - usually to the right. However, a study using cameras mounted on the backs of blue whales confirmed that when they ate, they switched to partiality. The results were published
Journal.
six years, scientists attached labels equipped with cameras, hydroreceptors and motion sensors to the backs of 63 blue whales living off the coast of Southern California. These labels will detach from the back of the blue whale and float to the surface after a few hours. In this way, they can be recovered and the data is downloaded by the researchers.
blue whale is known for its stunning "stunt" of pounce-like eating near the ocean's surface. When they jump up and dive into tiny groups of crustaceans (krill), they perform a 360-degree barrel roll. Video evidence shows that they almost always roll to the left.
this is in stark contrast to the way they usually eat deeper in the ocean. Deep in the water, they perform a 90-degree right-hand turn. Lead researcher Ari Friedlaender, of Oregon State University's Marine Mammal Institute, said flipping left during a pounce can make the blue whale's dominant right eye more effective at smaller krill populations.
"We were completely shocked by these findings. However, this behavior appears to be really efficient and consistent with the mechanisms that drive their routine foraging behavior, taking into account the methods used by blue whales to attack smaller prey populations. Friedlaender said. This is the first known example of an animal changing its bias to accommodate the scenario in which it performs a task. (Source: Science Network Xu Xu)
