Manta and devil rays are filter-feeding elasmobranchs that are found circumglobally in
tropical and subtropical waters. Although relatively understudied for most of the Twentieth …

White sharks, Carcharodon carcharias, are often described as elusive, with little information
available due to the logistical difficulties of studying large marine predators that make long …

Knowledge of the three-dimensional movement patterns of elasmobranchs is vital to
understand their ecological roles and exposure to anthropogenic pressures. To date …

Discerning behaviours of free-ranging animals allows for quantification of their activity
budget, providing important insight into ecology. Over recent years, accelerometers have …

Acoustic telemetry has become a popular means of obtaining individual behavioural data
from a wide array of species in marine and freshwater systems. Fate information is crucial to …

Some fishes and sea turtles are distinct from ectotherms by having elevated core body
temperatures and metabolic rates. Quantifying the energetics and activity of the regionally …

An understanding of the role that large marine predators play in structuring trophic flow and
nutrient cycling in marine ecosystems requires knowledge of their fine-scale (m-km) …

Bycatch mortality is a major factor contributing to shark population declines. Post-release
mortality (PRM) is particularly difficult to quantify, limiting the accuracy of stock assessments …

Short battery life limits the applicability of wearable sensors in animal behaviour monitoring.
This research developed an ear-attached acceleration sensor of low power consumption for …

Large pelagic fishes often dive and surface repeatedly as if they were airbreathers, raising a
question about the functions of these movements. Some species (eg, bigeye tuna, ocean …
