“Two species that are especially prone to biting are the snapping turtle (which is found in most water bodies throughout the state) and spiny softshell (which is found in most water bodies aside from wetlands and ponds throughout the state).”
“Give both turtles plenty of space (3-5 ft) if encountered on land.”
“If it is mid-May through early July, the turtle in your yard is likely looking for a place to lay eggs.”
