Rubber Duck
Gorilla
The gorilla, whilst physically formidable, operates under severe biological constraints that limit its temporal endurance. With a maximum lifespan of approximately 40 years in the wild—and perhaps 50 in captivity—the great ape represents an evolutionary compromise between power and permanence. The silverback's impressive musculature, capable of generating forces exceeding 1,800 pounds per square inch, paradoxically accelerates cellular degradation.
Furthermore, the gorilla's durability is contingent upon a complex web of environmental requirements: specific dietary provisions, appropriate social structures, and territories free from human encroachment. Remove any single element, and the mighty ape's existence becomes precarious. The rubber duck, by contrast, asks nothing of its environment save occasional drying.
