Top 22 most powerful bite forces in carnivore land mammals

Bite force is an important property of carnivore ecology because these amazing animals need to kill their prey as easily as possible, and the bite force is a vital factor in this context. Here are the top 22 most powerful bites in carnivore land mammals.

The values below are average bite forces at the canine tips and taken from the most recent and accurate 2007 research titled Bite Forces and Evolutionary Adaptations to Feeding Ecology in Carnivores by Per Christiansen and Stephen Wroe of the Ecological Society of America.
