How do the functions of the water deer's tusks compare to the function of typical deer antlers?
Answer
Tusks function as year-round piercing weapons for territorial contests.
Antlers in most deer species primarily function as seasonal displays of fitness, employed in ritualized sparring and posturing during the rutting period. In contrast, the Chinese water deer's modified canine tusks serve a different purpose, acting as direct, fixed piercing weapons that males deploy throughout the year, particularly during serious territorial contests. This reliance on a permanent, direct weapon suggests an evolutionary preference for visceral combat facilitated by a fixed implement over the energy investment required for the seasonal cycle of growing and shedding antlers, marking a significant functional difference within the deer family.
