hit by lawn mower, poor prognosis with severe carapace fracture and head trauma
There are two extant species of the family Chelydridae: Chelydra serpentina, the Common Snapping Turtle, and its larger relative Macrochelys temminckii, the Alligator Snapping Turtle (although the monotypic Asian genus Platysternon has at times been included in this group). Both are endemic to the Western Hemisphere.
