FIGURE 4.8. Waveforms of four successive clicks from each of two sperm whales.
The left column represents four successive clicks from one sperm whale and the
right column represents four successive clicks from different sperm whales. Note
how similar the pattern of pulses within each click is for each sperm whale and how
different the pattern of pulses is for the two different whales. (From Backus and

the IPI of their clicks, and he found a clear relation between IPI and estimated size of the spermaceti organ.
3.1.4.2 Functions of Sperm Whale Clicks
Sperm whales feed on squid at depths of 400 to 600m during dives that typically last 40 to SO minutes (Papastavrou et at. 1989). When sperm whales
dive and forage, they tend to produce long series of click sounds with
relatively stable interpulse intervals of 0.5 to 2.0 seconds (Whitehead and
