mate

And neither does my first mate.

Oh, I love it mate.

They do so as camouflage against the very faint sunlight, to send signals to potential mates, or to confuse and scare attackers.

And the fact that he's guarding her suggests she's in oestrus and ready to mate.

Having finally found a receptive female, Matt won't have a chance to mate unless he can get her away from the other males, and that's no mean feat.
