The sea lions are chasing people and bitting some if they get to close to their area. This is an action not normal to the m. Some saw it is due to a toxic red tide, others it is because their food supply is depleated to some extent. Happening along California coast and a few in Alaska. Sounds very plausible but ??? Have not heard of other strange animal behavior in the area but it does not always make the news. Something to watch and ponder a possible connection.
