Last month I took my family over to Olympia, and decided to go see the Oregon Zoo. Primarily to see the Stellar Sea Lions. Here is a picture of one of the Stellar Sea Lions. They are huge. I'll update later with some of the other pictures.
Oh yeah, this big boy stood on his front flippers at well over 5' 6", and towered over the keeper, and this is just from head to the flippers. When they were swimming like pictured, they were probably 10' long!!
The incredible part was when the keepers came to feed them. I'll post a vid of that later. The two of them jumped out of the water and could tower over the keepers when they stood up, and the keepers were about 5'10" they look little, but aren't!
