Mud Snake

 

 
38"-81" long, a shiny, blue-black snake with pink or red belly bars extending upward onto the sides.  Body is cylindrical, and the tail is short and tipped with a sharp spine.  This snake is found throughout the southeastern coastline and up the Mississippi drainage, particularly in swampy or weedy margins of lakes, streams, and sloughs.  Burrows in sandy soil under wet debris and mats of vegetation along the water's edge.  Feeds primarily on sirens and amphiumas.  Does not bite, but may poke you with the harmless spine.
