Otter Tracker

Have you ever wondered where sea otters swim along the California coastline throughout the year?

Introducing Otter Tracker!

Why do scientists capture, tag and track sea otters?
Capturing, tagging and tracking sea otters help scientists gain a better understanding of how they live and the contributing factors threatening the recovery of the species.  By surgically implanting a small device in their abdomens, researchers can track and monitor their overall health, foraging habits and reproduction success.  These multi-year studies, which typically involve a study group of several dozen animals, are conducted by a collaborative team of researchers from the Monterey Bay AquariumU.S. Geological SurveyUniversity of California Santa Cruz, and theCalifornia Department of Fish and Wildlife.

This research is authorized by the U.S. Fish & Wildlife Service. USFWS is responsible for the recovery and management of the southern sea otter, and is the authorizing agency for research permits concerning many threatened and endangered species.
