How many of your ancestors were jaguars? That’s evolution for you. SINAA is very very old, but able to shed his skin when he takes a bath and put on a new shiny one.
He also has eyes in the back of his head. Perhaps that helps him to see hidden things as he seems to have great knowledge and foresight. This he bestows upon selected medicine men such as UAICA on a need-to-know basis.
But only he knows the whereabouts of the large forked stick that holds up the sky. One day he’ll pull it down and the world will end.
