I have never killed a coral since they pose such little threat, pit vipers kill my dogs and like to be where my grand kids play so they die on sight. I absolutely agree that when away from the swimming hole or residence they are best left alone. We do not shoot coyotes or foxes, too much fun to watchYeah i was always more concerned when they pose a threat as there is a purpose for them. Now some species are much more aggressive than others so I do know many people who see corals are more concered as they ahve the most deadly venom compared to a cottonmout, rattler or cooperhead.
