Beyond looks, their day-to-day life ruminate their unparalleled evolutionary specializations. Beaver are famous as ecosystem engineer, actively modifying their surround to suit their needs, whereas otter are nomadic hunters that inhabit exist dens.

The Master Architects vs. The Playful Hunters

Oregonian construct luxuriant society and dekameter to make deep-water ponds that protect them from predators.
