This is a video from free-diver, surfer, conservationist and harbor seal enthusiast Michael Boyd, who has befriended a harbor seal named Mowgli, who kindly provides him with complimentary tickles and hair combing.

This is a video from La Jolla in San Diego of two sea lions charging at waaaaay too tourists for such a tiny beach, all of whom have clearly overstayed their welcome. They don’t call them lions for nothing! The city is considering closing this beach as a result of
