Delphinid communication has been shaped by the marine environment. This resulted in
specific adaptations such as echolocation and a sophisticated communication system that …

Until the 1990s, beaked whales were one of the least understood groups of large mammals.
Information on northern bottlenose whales (Hyperoodon ampullatus) and Baird's beaked …

Beaked whales have mass stranded during some naval sonar exercises, but the cause is
unknown. They are difficult to sight but can reliably be detected by listening for echolocation …

Beaked whale echolocation signals are mostly frequency-modulated (FM) upsweep pulses
and appear to be species specific. Evolutionary processes of niche separation may have …

Beaked whales are deep diving elusive animals, difficult to census with conventional visual
surveys. Methods are presented for the density estimation of beaked whales, using passive …

Toothed whales are apex predators varying in size from 40-kg porpoises to 50-ton sperm
whales that all forage by emitting high-amplitude ultrasonic clicks and listening for weak …

Mass stranding of several species of beaked whales (family Ziphiidae) associated with
exposure to anthropogenic sounds has raised concern for the conservation of these species …

At least ten species of beaked whales inhabit the North Pacific, but little is known about their
abundance, ecology, and behavior, as they are elusive and difficult to distinguish visually at …

Long‐term distribution data for cetaceans are lacking, inhibiting the ability of management
bodies to assess trends and react appropriately. Such is true even along the US Atlantic …

Closely related species are expected to diverge in foraging strategy, reflecting the
evolutionary drive to optimize foraging performance. The most speciose cetacean genus …
