Cotton Mouth (water moccasins) TPWD Kids: Venomous Snakes (habitat marshes, swamps, ponds, lakes, ditches, canals in East Texas and along Gulf Coast) They are very defensive and can be defensive... and they can bite under water!
Texas blind snake. Beneficial...they eat termite larva that could otherwise eat up your house. Our kitties used to bring these inside the house all the time, alive! I loved saving them...they're teeny tiny and look like worms so don't mistake them! Cute little guys.
