The word umwelt comes from biology, coined by ethologists studying animals in their natural habitats. It refers to the world as an organism can perceive it, based entirely on its sensory equipment. A bat's umwelt is built from echo. A dog's from scent. A tick's world is dominated by a single chemical cue that tells it when to drop from a branch onto a passing mammal.
