Hawaiian Whales Show 'No Overt Response' To Sounds Of ATOC Simulation
... Hawaii, Frankel said. One concern is for animals capable of diving through the so-called "deep sound channel," the 800- to 900-meter deep layer of water that catches and transmits sounds much farther than shallower parts of the ocean. Sperm whales are known to frequent the deep sound channel, but they ...Human-Like Ability, Categorical Perception, Found In Insects
