The
giant armadillo (
Priodontes maximus), colloquially
tatou,
ocarro,
tatu-canastra or
tatú carreta, is the largest living
species of
armadillo (although the extinct
glyptodonts were much larger). It was once found widely throughout the
tropical forests of
South America and now ranges throughout varied habitat as far south as northern
Argentina. This species is considered vulnerable to extinction.
