Natural selection catches up to all of us.
As part of 1111′s A-Z of Creatures. A is for Armadillo. Armadillos are found in both North and South America and even though there are around twenty different species, only two can roll up into a ball to protect themselves from predators (the Brazilian and the Southern Three Banded Armadillo). Most armadillos flee to evade predators and can reach speeds of up to 30mph (50kmph). Though, there is no fleeing from global warming either.
