These pictures were taken in 2013 of a Coral snake. I had a mule and she stomped it to death. The horses snorted and shied at it, even with it being dead, but not the mule.
I rolled it over to show the colors better.
The old saying tells you which one is poisonous. Red and yella-kill a fella. Red and black-friend of Jack. Coral snakes are in the Cobra family and highly poisonous. There are several snakes with similar coloring but are not poisonous.
