Animal's eye view of the ocean

Science Sessions are brief conversations with cutting-edge researchers, National Academy members, and policymakers as they discuss topics relevant to today's scientific community. Learn the behind-the-scenes story of work published in the Proceedings of the National Academy of Sciences (PNAS), plus a broad range of scientific news about discoveries that affect the world around us.

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. •[06:12] Takuya Maekawa, an engineer at Osaka University in Japan, designed a device to detect and automatically record rare behaviors performed by streaked shearwaters. •[07:56] Final thoughts and conclusion.
