Have you guys been watching this???
Here is another pic....
That's crazy! Is the whale sick or injured?
(Remember when a whale was found in the Thames? It was young female who was badly injured. Postmortem, they found several gashes along its underbelly, head and dorsal fin, most likely caused by collisions with boats and rubbing against the rocky river bed.)
I think they just got off the path they were going. It is a baby and momma. This has happened here a few years back. I guess they come in through San Francisco Bay and find their way into the river.
