First sea lion selfie

First sea lion selfie

Last updated: January 25, 2020 at 6:09 am

Steller sea lion — Russell Clark‘s 360° camera was momentarily engulfed by a Steller sea lion during a dive off Hornby Island, British Columbia, in 2019. The resulting image became the world’s first selfie taken from within the mouth of a pinniped. Stellers, the world’s largest sea lion, as well as California sea lions, the world’s fastest pinniped, gather in large numbers from November to February off east Vancouver Island, specifically near Norris Rocks.

“This haul out is a holding cell for these rambunctious guys (they’re all male), whilst they patiently wait for the huge herring run that takes place in March and April. Think of it as Canada’s answer to the sardine run in South Africa.” — Russell Clark

Russell Clark is co-owner of Seaproof.tv and the editor of DIVER Magazine, the longest established scuba magazine in North America.
