Rubber Duck
Otter
The individual otter possesses a finite biological lifespan of approximately fifteen to twenty years in the wild. However, this metric fundamentally misunderstands durability. The otter species has endured for thirty million years, adapting to ice ages, continental shifts, and the rise and fall of civilisations. Each otter carries genetic information refined across countless generations, a living library of survival strategies. They self-repair from injuries, adapt to environmental changes, and produce successive generations that inherit accumulated wisdom. The rubber duck's durability is static preservation; the otter's durability is dynamic perpetuation through time itself.
