Hard to see and lots of text in my horrible hand writing. >.< Some quick refs for how Mak's face/mouth looks along with some of the crap that goes along. I'll type out similar text in here for those who are interested.

-Has flaps in his nostrils that can seal off the nasal cavity.
-A protective membrane slides over eyes to make up for not having eyelashes. It's very strong but cloudy. They also serve as protection when he is fighting.
-The back of his throat has a flap like a crocodile's.
