Korean Water Deer
Hydropotes inermis argyropusAlso known as Korean Vampire Deer, Tusked Deer, River Deer
Korean water deer are unique small cervids that lack antlers entirely, relying instead on long, mobile upper canine tusks for social defense and rival displays. Native to wetlands, river valleys, and agricultural fields across the Korean Peninsula, they are exceptional swimmers capable of crossing wide rivers to reach fresh feeding grounds. Active mostly at dawn and dusk, they communicate through raspy alarm barks and high-pitched squeaks while browsing on tender vegetation.
