Short-finned pilot whales modulate surfacing and breathing patterns more strongly in response to dives than in anticipation Open
A new study reveals how short-finned pilot whales balance the conflicting demands of foraging underwater with breathing at the surface. Using data from digital tags, scientists found that pilot whales rely more on surfacing strategies that…

Short-finned pilot whales modulate surfacing and breathing patterns more strongly in response to dives than in anticipation Open
Diving marine mammals must allocate time between respiring at the surface and foraging underwater. Previous studies of optimal diving theory have attempted to predict such patterns, but the amount of time divers must spend at the surface b…

Drivers of biosonar click rates in bottlenose dolphins (Tursiops truncatus) over the West Florida Shelf Open
Understanding cetacean echolocation behavior is important for effective population monitoring and conservation. Using passive acoustic monitoring (PAM), researchers can listen for the biosonar clicks produced by echolocating animals to est…

Song fragments recorded on a tagged juvenile humpback whale (<i>Megaptera novaeangliae</i>) on a winter feeding ground at the mouth of the Chesapeake Bay, Virginia, <span>USA</span> Open
Humpback whales produce a variety of sound types, including vocalizations termed “songs” because they consist of repeated, fixed patterns of sounds, similar to bird songs (Payne et al., 1971). Humpback songs consist of themes, phrases, uni…

Short-finned pilot whales exhibit behavioral plasticity in foraging strategies mediated by their environment Open
Predators adapt their foraging behavior to exploit a variety of prey in a range of environments. Short-finned pilot whales are wide-ranging predators in tropical and sub-tropical oceans, but most previous studies of their foraging ecology …

Extreme diving in mammals: first estimates of behavioural aerobic dive limits in Cuvier's beaked whales Open
We analysed 3680 dives from 23 satellite-linked tags deployed on Cuvier's beaked whales to assess the relationship between long duration dives and inter-deep dive intervals and to estimate aerobic dive limit (ADL). The median duration of p…

Diving behaviour of Cuvier's beaked whales (<i>Ziphius cavirostris</i>) off Cape Hatteras, North Carolina Open
Cuvier's beaked whales exhibit exceptionally long and deep foraging dives. The species is little studied due to their deep-water, offshore distribution and limited time spent at the surface. We used LIMPET satellite tags to study the divin…
