1. Despite their importance in determining the rate of both energy gain and expenditure, how the fine-scale kinematics of foraging are modified in response to changes in prey abundance and distribution remain poorly understood in many animal ecosystems. 2. In the marine environment, bulk-filter feeders rely on dense aggregations of...
For decades, the bio-duck sound has been recorded in the Southern Ocean,
but the animal producing it has remained a mystery. Heard mainly during
austral winter in the Southern Ocean, this ubiquitous sound has been
recorded in Antarctic waters and contemporaneously off the Australian
west coast. Here, we present conclusive...
Air-breathing marine animals face a complex set of physical challenges associated with diving that affect the decisions of how to optimize feeding. Baleen whales (Mysticeti) have evolved bulk-filter feeding mechanisms to efficiently feed on dense prey patches. Baleen whales are central place foragers where oxygen at the surface represents the...
It is a golden age for animal movement studies and so an opportune time to assess priorities for future work. We assembled 40 experts to identify key questions in this field, focussing on marine megafauna, which include a broad range of birds, mammals, reptiles, and fish. Research on these taxa...
