Megafauna

Large animals

In zoology, megafauna (from Greek μέγας megas 'large' and Neo-Latin fauna 'animal life') are large animals. The precise definition of the term varies widely, though a common threshold is approximately 45 kilograms (99 lb), this lower end being centered on humans, with other thresholds being more relative to the sizes of animals in an ecosystem. The spectrum of lower-end thresholds ranges from 10 kilograms (22 lb) to 1,000 kilograms (2,200 lb), the latter largely restricted to megaherbivores.
