My favorite trivia here is that flamingos aren't actually "genetically" pink but "environmentally" pink because they pick up the color from eating algae.

Except of course "genetics" and "environment" aren't actually separate things; sure, people's skin color isn't usually affected by their food, but only because most people don't eat colloidal silver.

AFAIK most poisonous frogs also aren’t “naturally” poisonous—they get it from diet. Ones raised in captivity aren’t poisonous unless you go out of your way to feed them the things they need to become poisonous.
