Hyena crept slowly round, making the most of his spotted brown camouflaged fur against the brownish stems of grass.
This is sometimes called a bracketing comma. In this case, "Hyena crept slowly round" is a complete sentence/clause on its own. The additional text can be called (as in the page linked to) an "interruption", and is marked off with a comma.
(Also note that, if you were reading this aloud, you'd most likely pause where that comma is, indicating that it's something in addition to the main part of the sentence.)
