Behavior is an important mechanism of evolution and it is paid for through energy
expenditure. Nevertheless, field biologists can rarely observe animals for more than a …

ABSTRACT 1 Since the last thorough review of the effects of anthropogenic noise on
cetaceans in 1995, a substantial number of research reports has been published and our …

Inertial aquatic swimmers that use undulatory gaits range in length L from a few millimetres
to 30 metres, across a wide array of biological taxa. Using elementary hydrodynamic …

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 …

The energetic costs of different behaviours are critical in modulating the behavioural ecology
of free‐living animals. Despite this, measurement of energy expenditure in the field has …

Mid-frequency military (1–10 kHz) sonars have been associated with lethal mass strandings
of deep-diving toothed whales, but the effects on endangered baleen whale species are …

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 …

behaviour.•We highlight four areas of technological advances.•Aerial systems …

Lunge feeding by rorqual whales (Balaenopteridae) is associated with a high energetic cost
that decreases diving capacity, thereby limiting access to dense prey patches at depth …

Baleen whales are gigantic obligate filter feeders that exploit aggregations of small-bodied
prey in littoral, epipelagic, and mesopelagic ecosystems. At the extreme of maximum body …
