Data from: The influence of preceding dive cycles on the foraging decisions of Antarctic fur seals
The foraging strategy of many animals is thought to be determined by their past experiences. However, few empirical studies have investigated whether this is true in diving animals. We recorded three-dimensional movements and mouth-opening events from three Antarctic fur seals during their foraging...

The foraging strategy of many animals is thought to be determined by their past experiences. However, few empirical studies have investigated whether this is true in diving animals.

Each dive cycle was divided into a transit phase and a feeding phase.
