Wow! It turns out that the Sea Lions we saw before our Sunset Cruise from Pier 39 in San Francisco (photos at the bottom this post) have suddenly and mysteriously disappeared! They had been hanging out there for 20 years (their initial arrival was apparently just as unexpected)!
Reason for this seems to be unknown, but some are positing following some new food source. Who knows for sure – but I am glad we had a chance to document them!
