Underneath Pier 33 is the best-kept secret...

...for Sea Lions. From the offices of Pier 35, a lone sea lion was seen swimming where cruise ships often dock. He then went under Pier 33, we think, because it is probably not over fished by other sea lions and he will eventually be able to retreat back to the docks for a long, satiated nap with the others. 

In addition to swimming near cruise ports, every now and then one or several sea lions can be seen breaking away from the PIER 39 crowd and hanging out by sail boats docked in between piers 39 and 35. Generally, the closer you get to PIER 39, the more sea lions you will see! 
Sea Lions are considered “opportunistic feeders,” eating available prey rather than one species.
The average life span of a California Sea Lion is 20–25 years.
