Sadly, since sunfish are fairly isolated creatures, you're most likely to see one for yourself as it's ripped apart by seals along the California coast. It's not clear whether seals (and sea lions) try and fail to eat the fish or if they just like to kill for sport, but the mammals seem to enjoy tearing sunfish fins off and then abandoning the body. Without their fins, the poor sunfish drift to the bottom of the ocean, alive but unable to swim back up. Helpless, they're slowly eaten by other sea creatures. And so ends the life of the peaceful sunfish. Gone, but not forgotten.
