Underwater behavioral patterns of one Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis) calf in captivity and those performed on the water surface by two calves in semi-natural environment were focally followed…
The harbor porpoise, and other toothed whales, use a biosonar click sequence that resembles the sequence of cries used by insectivorous bats when hunting for and capturing prey. The temporal…
