User blog comment:Lord Loss/Monster Hunter Theory... Blog/@comment-1758220-20110706160008/@comment-1011548-20110706200644

The whole 'Rathian/Rathalos change colour with age' thing almost certainly comes from the AzureRathalosCarapace description in Unite, which says something to the effect of 'Made from scales hardened during adolescence.' Obviously this isn't explicit, but it gave lots of people (including me) the impression that Azure/Pink must be... adolescents, and that Red/Green were younger and Gold/Silver were older. Gold and Silver being rarer could be explained by fewer Rath's living to that age.The problem is that their ecology on Bobo's website, which is based on translations from official books, say that it's down to 'gene mutations'. So bleh. There's one sentence on the Pariapuria page that suggests it physically vomits up its guts, and that could've been written by anyone. Even if that is based on an actual in-game description of the monster, however (seems unlikely) then one could always argue that the Hunter is merely carving up the bits of meat 'n' stuff found in Pariapuria normal vomit. Yum! The real question is why on earth they'd want to do that.
