...I guess it can be classified as.
Returning from tuna fishing in Mexican waters, about a mile south from the Coronado Islands, we ran into 2 Fin Whales yesterday. They were feeding on the krill, they were circuling tight big orange balls of krill.
I don't know if it was in self-defense, but one of them took a huge dump.
Now you know what whale's poop looks like - this one was orange/pinkish, just like the krill they've been feasting on.
