Deep-diving foraging behaviour of sperm whales (Physeter macrocephalus).
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 Atlantic Ocean, the Gulf ofExpand

Sperm whale behaviour indicates the use of echolocation click buzzes ‘creaks’ in prey capture
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’. Sound, depth andExpand

Stroke frequency, but not swimming speed, is related to body size in free-ranging seabirds, pinnipeds and cetaceans
It is obvious, at least qualitatively, that small animals move their locomotory apparatus faster than large animals: small insects move their wings invisibly fast, while large birds flap their wingsExpand

Swimming gaits, passive drag and buoyancy of diving sperm whales Physeter macrocephalus
SUMMARY Drag and buoyancy are two primary external forces acting on diving marine mammals. The strength of these forces modulates the energetic cost of movement and may influence swimming styleExpand

Call-type matching in vocal exchanges of free-ranging resident killer whales, Orcinus orca
Previous sound recordings of resident (fish-eating) killer whale groups have revealed matrilineal groupspecific call repertoires and a strong tendency for calls of the same type to be produced inExpand

Quantitative measures of air-gun pulses recorded on sperm whales (Physeter macrocephalus) using acoustic tags during controlled exposure experiments.
The widespread use of powerful, low-frequency air-gun pulses for seismic seabed exploration has raised concern about their potential negative effects on marine wildlife. Here, we quantify the soundExpand

Sink fast and swim harder! Round-trip cost-of-transport for buoyant divers
SUMMARY Efficient locomotion between prey resources at depth and oxygen at the surface is crucial for breath-hold divers to maximize time spent in the foraging layer, and thereby net energy intakeExpand

The Severity of behavioral changes observed during experimental exposures of killer (Orcinus orca), long-finned Pilot (Globicephala melas), and sperm (Physeter macrocephalus) whales to naval sonar
This study describes behavioral changes of wild cetaceans observed during controlled exposures of naval sonar. In 2006 through 2009, 14 experiments were conducted with killer (n = 4), long-finnedExpand
