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.
