Brief

The African elephant’s ~2,000 olfactory receptor genes give it far superior smell: it can detect water 12 miles away, locate a ripe tree from kilometers, and differentiate human groups by scent. In the posted video she constantly resamples the air with her trunk, had already mapped the fruit buffet, and entered backwards to let people think she was surprised.

Why it matters

African elephants carry about 2,000 olfactory receptor genes versus 396 in humans and ~800 in bloodhounds, meaning an elephant's trunk has roughly five times the scent hardware of a human and twice that of a dog.

Key details

  • Elephants can scent water up to 12 miles away, lock onto a single ripe tree from kilometers off, and reportedly distinguish human groups by smell; in the shared clip the elephant continuously sweeps her trunk and had already identified each fruit on a table before turning around and entering backwards to let people be surprised.
Cleaned source text

An animal that smells water from 12 miles out is not getting surprised by a fruit table six feet away.

The African elephant carries close to 2,000 olfactory receptor genes, the most ever counted in any animal. You have 396. A bloodhound has around 800. So the nose at the tip of that trunk runs roughly five times the scent hardware a human does and twice a dog's.

Watch the trunk in the clip. It never stops sweeping the air, resampling the scene the way your hand feels around a dark room. By the time she "walks in," she has already read everything on that table down to which slice is freshest.

The backwards entrance was staged for the people filming it. She knew exactly what was waiting. She just let everyone have the moment.
