Hedgehog
In matters of raw physical capability, the hedgehog occupies the lower registers of mammalian achievement. With a maximum running speed of approximately 6 kilometres per hour and limbs designed for modest burrowing rather than combat, this creature poses no physical threat to anything larger than a beetle. The hedgehog's bite, whilst adequate for crunching through invertebrate exoskeletons, would scarcely inconvenience a determined house cat. Indeed, the hedgehog's entire evolutionary strategy presupposes an inability to win physical confrontations through conventional means.
Gorilla
The silverback gorilla represents one of nature's most impressive displays of primate musculature. Conservative estimates suggest these animals can lift approximately 815 kilograms—roughly ten times their body weight. Their arms, measuring up to 2.5 metres in span, generate sufficient force to bend steel bars and have been documented casually dismantling termite mounds reinforced to concrete-like hardness. A gorilla's grip strength exceeds 400 kilograms of force, rendering escape from their grasp essentially impossible for any creature without superhuman capabilities.
