List of mammals of Guatemala

Species assessed using this system have the following instead of near threatened and least concern categories: Didelphimorphia is the order of common opossums of the Western Hemisphere.

Opossums probably diverged from the basic South American marsupials in the late Cretaceous or early Paleocene.

They are small to medium-sized marsupials, about the size of a large house cat, with a long snout and prehensile tail.

The order Primates contains humans and their closest relatives: lemurs, lorisoids, tarsiers, monkeys, and apes.

Shrews and solenodons closely resemble mice, hedgehogs carry spines, while moles are stout-bodied burrowers.

They are the mammals most fully adapted to aquatic life with a spindle-shaped nearly hairless body, protected by a thick layer of blubber, and forelimbs and tail modified to provide propulsion underwater.
