In this episode, researchers use animal-borne video cameras to explore foraging behaviors of animals in the open ocean.

In this episode, we cover:
•[00:00] Introduction
•[00:46] Taiki Adachi, an ecologist at the National Institute of Polar Research in Japan, observed how elephant seals use their whiskers to locate prey in the dark depths of the ocean
•[02:13] Carey Kuhn, an ecologist at the Alaska Fisheries Science Center in Seattle, Washington, explored how the size of prey affected the foraging behavior of northern fur seals.
•[03:43] Ryan Logan, an ecologist at California State University Long Beach, recorded a solitary sailfish hunting in the open ocean and estimated its energy expenditures.
•[05:05] Simone Videsen, an ecologist at Aarhus University in Denmark, performed a similar analysis of the energetic efficiency of humpback whales.
