Kangaroos and Wallabies

It’s widely known that kangaroos trump wallabies in size,
But when the roos are young, they may be hard to recognize.
Another way to tell is from the colors of their fur.
In wallabies, two hues or more are likely to occur,
Most often bright and shiny, tho they sometimes come in black.
They live in wooded regions, so their legs are more compact,
While roos have lots of length between the ankles and the knees
For speed across a flat terrain without a bunch of trees.
Their habitats explain as well distinctions in dentition:
The roos eat grass; the wallabies have leaves for their nutrition,
And thus they grow premolars that they never have to lose,
Plus one small cutting tooth, unlike the ridges in the roos.
A roo tail’s like a leg, so it prevents the roo from sitting.
You might find other differences, but this is where I’m quitting.
