We often saw sea lions on our island walks, and they never moved away. Though at times past they were killed by visiting sailors or pirates, the sea lions in the islands are generally very, very trusting of people. We walked within a foot of them, often having to step over them or very nearly so on many of the islands. Sometimes sea lions would walk past us, or even along with us.
We saw (and heard) them nursing. We saw healthy young, and unfortunately, a few who lost their moms and were not going to make it. We saw wet sea lions, dry sea lions, sea lions of all sizes. We saw them swimming, sleeping, and playing.
Once in awhile a big male would warn us to stay out of his territory with big deep barks. No problem - easy enough to do. They were never any threat. I have been shocked that nearly every person who asked about the trip, when Is aw we snorkeled with sea lions, says "Isn't that dangerous?" These are gentle creatures that eat fish. They chose to approach us, we are not approaching them. They are a million times faster than us in the water. They come over to play and check us out - it would never occur to me to be the least bit fearful of them as long as one is respectful of their space.
