Mountain lion kill adult cow elk
I have more photos if needed. I believe there were two individuals. I only had enough time to watch them for about 5 minutes. During that time, there was a near constant flipper splashing, half breaching, and spyhopping.
Right off the bat I believe this is either a humpback whale or N.A. right whale. Due to the flipper shape and absence of dorsal fin lead me to believe this is a N.A. right whale.
