Pacific white-sided dolphins are only one of the many mammals often viewed on the whale watching day. Dolphins tend to travel in pods of several hundred the largest pod I have come across was between fifteen hundred and two thousand. This was in the late fall and they appeared to be heading out of the area. The pods we encounter in the summer are playful and come to our boats out of curiosity. In this case we were stationary as the dolphins were following another of our boats. At other times they will pass beneath our bow while we move along side a large pod.
