Proboscis and olfaction

The moose proboscis is distinctive among living cervids due to its large size; it also features nares that can be sealed shut when the moose is browsing aquatic vegetation. The moose proboscis likely evolved as an adaptation to aquatic browsing, with loss of the rhinarium, and development of a superior olfactory column separate from an inferior respiratory column. This separation contributes to the moose's keen sense of smell, which they employ to detect water sources, to find food under snow, and to detect mates or predators.
