With counts exceeding 100 animals, Elkhorn Slough has the highest concentration of southern sea otters on the California coast. It is in this estuary habitat that researchers have observed sea otter behavior not seen in other sea otter populations. The Elkhorn Slough OtterCams are a joint program of Elkhorn Slough National Estuarine Research Reserve, Elkhorn Slough Foundation and Friends of the Sea Otter that allows the public to view sea otters in the sheltered channels of the Elkhorn Slough.

Having difficulties seeing the otters or have questions? See our Frequently Asked Questions.

If you are visiting during a time when the otters are out foraging (or perhaps when the camera is being used by one of our researchers), please enjoy the video highlights below. For more information about sea otters click here.
