Large whales are subjected to a variety of conservation pressures that could be better
monitored and managed if physiological information could be gathered readily from free …

Many marine animals use sound passively or actively for communication, foraging, predator
avoidance, navigation, and to sense their environment. The advent of acoustic recording …

Sound-and-orientation recording tags (DTAGs) were used to study 10 beaked whales of two
poorly known species, Ziphius cavirostris (Zc) and Mesoplodon densirostris (Md). Acoustic …

For many marine organisms, especially large whales that cannot be studied in laboratory
settings, our ability to obtain basic behavioral and physiological data is limited, because …

Summary 1 Digital tags were used to describe diving and vocal behaviour of sperm whales
during 198 complete and partial foraging dives made by 37 individual sperm whales in the …

Mortality from collisions with vessels is one of the main human causes of death for large
whales. Ship strikes are rarely witnessed and the distribution of strike risk and estimates of …

During foraging dives, sperm whales (Physeter macrocephalus) produce long series of
regular clicks at 0.5–2 s intervals interspersed with rapid–click buzzes called 'creaks' …

1. Empirical testing of optimal foraging models for breath-hold divers has been difficult. Here
we report data from sound and movement recording DTags placed on 23 short-finned pilot …

Fin whales are among the largest predators on earth, yet little is known about their foraging
behavior at depth. These whales obtain their prey by lunge-feeding, an extraordinary …

Rorqual baleen whales lunge feed by engulfment of tons of prey-laden water in a large and
expandable buccal pouch. According to prior interpretations, feeding rorquals are brought to …
