This is a collab thing I did with  Ghostofyourdad (well, I maybe contributed a few ideas, some small text and the predator, but 98% of it was Ghost's work.)

Food chain:
Oan:  Ghostofyourdad
Lapis:  superorca
Atlas: mine

fluff:
By length Lapis was a tremendously challenging prey even for a colossus like Atlas. The blue shark was however pretty slender and while he was no spineless squid, he proved to be plenty flexible enough to be coerced up his sloped gullet. Even his long fins were hardly an obstacle on his involuntary quest to follow the path hundreds of lesser examples of his kind had already taken in the past. Still, with one last pull of Atlass’s experienced throat and a push of his massive tongue, Lapis was reduced from the biggest male blue shark ever to the mere top predator residing in a whale’s digestive tract.
