This was a relatively small snake of about two and half feet. They are known to grown to seven feet long! They also have their young in a big way: they may lay eggs in clutches that number over 100. (Talk about Labor Day!)
The belly scales are long, but the side scales are diamond-shaped. And, by the way, this snake is belly up; the back is shiny black.
Mud snakes are known to poke their pointy tail at you, if they become agitated.
That is some claim to fame!
