Echolocation Characteristics and Range Detection Threshold of a False Killer Whale (Pseudorca Crassidens)

False killer whales (Pseudorca crassidens) are deep-diving, pelagic, toothed whales that inhabit temperate and tropical oceans. Pseudorca prey on squid, large fish, and perhaps even dolphin (Tomich, 1986). They produce many types of sounds, including whistles, frequency-modulated sweeps, and pulses (Busnel and Dziedzic, 1968; Watkins, 1980).
