Sometimes! In the United States, we have three kinds of coral snake. The Florida coral snake is the one with the scariest reputation. Some people bitten by Florida corals go into ventilatory arrest (that’s where you totally stop breathing) from nerve paralysis. Texas coral snakes have a slightly less scary reputation, although we don’t have enough information to make a really strong statement about them. The Arizona coral snake is so small that it has a hard time getting enough venom into a person to cause harm (although the potency in the laboratory is pretty high). Further south, as you travel through Mexico and South America, there are a lot of different coral snakes, some of which are extremely dangerous. Of course, any snake can give what we call a “dry bite,” without serious medical consequences.
