krill. Among all animals, ants outweigh us in biomass — putting billions and billions of tons up against humans' fewer than 500 million. And while they're both tiny and lacking a backbone, krill are the champs among animals worldwide, in terms of numbers, with a population estimated at 500 trillion.
