Five subspecies recognized[1]:
- T. d. brachypterus from south Texas to west-central Mexico and Panama
- T. d. bangsi in western Mexico (southern half of Baja California and southern Sonora)
- T. d. dominicus on Cozumel Island, Bahamas, Greater Antilles and Virgin Islands
- T. d. eisenmanni on the coast of Ecuador; populations of northwestern Peru presumably also this subspecies
- T. d. brachyrhynchus in tropical northern South America to south Brazil and north Argentina
Habitat
Freshwater ponds, slow-flowing rivers and swamps.

Diet
Includes small fish and aquatic invertebrates.
