Super find, danescombe.

The largest is about 45' long. Location and size would suggest that these are Gray Whales , which breed and give birth in certain lagoons in Baja California, Blue Whales in this part of the world usually are found off Central California. The Santa Barbara Channel is their preferred hangout. They are up to 2+ times the length of Grays.

I added 6 more pods of whales nearby. There may well be others.

This is a Digital Globe image, and is dated February 23, 2006. This is about the time Gray Whale mothers and calfs should be heading back North . Maybe they are doing a bit of sightseeing...
