Male Pythios species!
Basically for the back view, the males have a super long spikey mane like a zebra, from head to mid-tail - remember the gems start at the top, just as seen on the tail.

They do not have pupils, but they can have a bright glow to show where the eyes are looking.

Oh, here is what their tongue/teeth look like! http://www.furaffinity.net/view/14086516/ (This is the male Feral form.) Their teeth are basically solid razors.
