^Banned for not looking it up. It's obvious no one consulted the 97th edition of the New Arkham American Dictionary (©2016 Miskatonic University, Arkham, MA) in which cryptocarnivorous does indeed appear. To wit: cryp·to·car·niv·o·rous adj. 1. Belonging or pertaining to the order Cryptocarnivora 2. Eating the flesh of cryptids. [New Latin, from Greek kruptos, hidden, from kruptein, to hide + Latin carnivorus, flesh-eating.]
