Squirrel
Panda
Giant pandas possess a bite force of roughly 2,600 PSI - actually exceeding that of most bears - a jaw strength evolved specifically for crushing bamboo stems that would otherwise resist consumption. They can, theoretically, cause significant damage to threats, though their preferred response to conflict is typically to sit down and look confused.
Adult pandas weigh up to 160 kilograms, with males occasionally engaging in what might generously be termed combat during mating season. These altercations largely involve falling over repeatedly whilst making sounds reminiscent of a distressed goat.
VERDICT
Despite the panda's impressive jaw mechanics, the conventional bear wins on overall athletic capability by a considerable margin. Bears are apex predators capable of taking down elk, moose, and the occasional unfortunate hiker. Pandas are capable of sitting down slowly and occasionally rolling off branches. The comparison, whilst unfair, is nonetheless scientifically valid.
