Brief summary of the paper: Logging cameras and accelerometers have opened our eyes to the secret lives of many enigmatic species.

Here some of the new opportunities provided by this technology are reviewed. Recent discoveries are highlighted including the observation of selective feeding on energy-rich parts of prey.

As such, biologging cameras provide new opportunities for consideration of selective feeding within the same sort of theoretical framework (marginal value theory/optimal foraging) that exploitation of prey patches has been examined.

A recent study with the world’s largest bony fish, the ocean sunfish (Mola mola), is highlighted where animal-borne cameras allowed the ground-truthing of data sets collected with depth recorders and accelerometers.

This synergistic use of a range of biologging approaches will help drive an holistic understanding of the free-living behaviour of a range of species.
