I always thought it was called a pod when referring to a group of dolphins or whales. Well, not only was I wrong about the dolphin aspect of that assumption, but I also just learned that it’s incorrect when referring to a large group of whales — only a small group of whales is referred to as a pod. Apparently all large groups of swimmy things are called schools. Who knew?
With all of their rape and murderous, baby-killing tendencies aside, dolphins are pretty damn cute and this would be absolutely incredible to experience. Just stay out of the water and your orifices should remain unmolested.
