He looks like a cross between a deer and a rabbit,

but Wesley is actually a rodent.

Patagonian maras are only found in parts of central

and south Argentina,

and even there they are becoming harder to spot.

These cute little guys top out at just under three feet,

and just over 30 pounds.

Their bodies are well adapted for running,

and they reach close to 45 miles per hour at full speed.

Grass makes up the majority of this herbivore's diet.

They prefer living in areas with lots of shrub cover

to protect themselves from predators.

However, a combination of overgrazing and hunting

for their skin has caused a steady decline

in their population.

This is the Patagonian mara.
