Scientists studying the world’s deepest diving mammals turned their thumbs up while diving off the coast of North Carolina.
According to Duke University in the United States, the average dive of Cuvier’s baked whales typically takes about an hour at a depth of about 1,400 meters.
But one of the mammalian scientists was surprised to disappear underwater for three hours and 42 minutes without once appearing in the air.
In a study published in the Journal of Experimental Biology, researchers found that they analyzed 3,680 dives, only 5% lasting more than 77 minutes.
However, its 222-minute long hunt for a squid among the Cetisians almost shook the figure.
The previous record, set in 2014 by the same whale species, was about two hours.
Experts believe that the Cuban beetle whale is able to survive under water for so long because it can rely on large stores of oxygen, is able to slow its heartbeat and has low metabolism.
Studies of species behavior are limited by the offshore position of the animals and the limited time spent on the surface.
“Their deep dives averaged about 1,400 meters, lasting about an hour while they were eating near the ocean floor,” said Jenny Shearer, a doctoral student in ecology at Duke University’s Encyclopaedia School of the Environment.
“They usually spend about two minutes on the surface between dives
“It’s amazing that they can dive to such depths, withstand stress and stay there longer with shorter recovery times.”
According to the Guinness Book of World Records, the longest time a person exhales under water is 24 minutes and 3.45 seconds.
The record was set in 2016 by Alex Segura Vendrell of Spain.
