A behavioural framework for the evolution of feeding in predatory aquatic mammals
Extant aquatic mammals are a key component of aquatic ecosystems. Their morphology,
ecological role and behaviour are, to a large extent, shaped by their feeding ecology …

Why whales are big but not bigger: physiological drivers and ecological limits in the age of ocean giants
The largest animals are marine filter feeders, but the underlying mechanism of their large
size remains unexplained. We measured feeding performance and prey quality to …

Using on-board sound recordings to infer behaviour of free-moving wild animals
Technological advances in the last 20 years have enabled researchers to develop
increasingly sophisticated miniature devices (tags) that record an animal's behaviour not …

[HTML][HTML] Cetaceans as ocean health indicators of marine litter impact at global scale
Marine litter is a growing concern for marine animals, including cetaceans for which there is
a developing body of evidence showing impacts of both entanglement and ingestion. Better …

[HTML][HTML] Echolocating toothed whales use ultra-fast echo-kinetic responses to track evasive prey
Visual predators rely on fast-acting optokinetic responses to track and capture agile prey.
Most toothed whales, however, rely on echolocation for hunting and have converged on …

The long-range echo scene of the sperm whale biosonar
Sperm whales use their gigantic nose to produce the most powerful sounds in the animal
kingdom, presumably to echolocate deep-sea prey at long ranges and possibly to debilitate …
