Dolphins are so fast, intelligent and agile that it is hard to believe
that they could be hunted and killed by another marine mammal but it
turns out that the orcas are pretty smart also, and they hunt in
packs.

About 15 years ago while trolling for salmon off San Juan Island a pod
of 6-8 Orcas passed by. Some passed directly below and others surfaced
just off the sides. I felt pretty vulnerable in a small 16' sled, it
was clearly their domain.
