Pilot whales-the 'cheetahs of the deep sea'

摘要

Until now, what happened in the depths where many whales hunt, stayed there.rnA new study has revealed that pilot whales are "the cheetahs of the deep sea," making 15-minute, high-speed, all-or-nothing dives up to 3,280 feet (1,000 meters deep) to chase and catch large squid, before surfacing to catch their breath.rn"They make colossal dives and must come back exhausted," said Natacha Aguilar de Soto, the study's lead author. "They have to spend time at the surface catching their breath before undertaking a new sprint to catch prey."
