The water deer, often called the “vampire deer” due to its distinctive tusks, is a small and unique species of deer native to China and Korea. Unlike most deer, water deer lack antlers and instead have prominent canine teeth. Adapted to life in wetlands and river valleys, these elusive creatures play a vital role in their ecosystems. This article delves into the fascinating world of water deer, covering their habitats, physical characteristics, behaviors, and much more.

Amazing Facts

Water deer possess numerous intriguing attributes:

  • Tusks: Unlike most deer, males have long, curved canine teeth, which can grow up to 3 inches (8 cm) and are used in combat and display.

  • Adaptability: They thrive in wetland habitats, including swamps, marshes, and riverbanks.
  • Excellent Swimmers: As their name suggests, these deer are adept swimmers and can move easily through water to escape predators.
  • Longevity: In the wild, they can live up to 12 years, while in captivity, they may live slightly longer.

Habitat and Food

These adaptable creatures thrive in specific environments that cater to their unique lifestyle.


  • Native to China and Korea, water deer inhabit wetlands, river valleys, and marshy areas.
  • They prefer environments with abundant water sources and dense vegetation, which provide cover from predators and access to food.
  • These deer are often found in reed beds, tall grasses, and brushy areas near rivers and lakes.


  • Herbivorous, with a diet consisting of grasses, leaves, aquatic plants, and shrubs.
  • During the spring and summer, they feed on a variety of herbaceous plants and fresh shoots.
  • In the fall and winter, they browse on woody vegetation and the bark of trees.
  • They are known to forage for cultivated crops, sometimes leading to conflicts with farmers.


Water deer are known for their unique and striking appearance. Key characteristics include:

  • Size: Adults stand about 1.5 to 2 feet (45 to 60 cm) tall at the shoulder and weigh between 20 to 31 pounds (9 to 14 kg).
  • Color: Their coat is generally reddish-brown in the summer, turning to a more grayish-brown in the winter. They have a lighter underbelly.

Predators and Threats

Despite their agility and adaptability, water deer face various natural and human-induced threats that impact their survival.

Natural Predators:

  • Tigers: In their native range, tigers are one of the primary predators.
  • Leopards: Leopards also prey on these deer, particularly targeting younger or smaller individuals.
  • Wolves: Packs of wolves can pose a significant threat, using teamwork to hunt.
  • Domestic Dogs: In areas near human habitation, domestic dogs may pose a threat to these deer.


  • Habitat Loss: Urban development, agriculture, and wetland drainage reduce available habitats.
  • Human-Wildlife Conflict: They often come into conflict with humans when they raid crops or are involved in vehicle collisions.
  • Poaching: Illegal hunting for their meat and hides can threaten specific populations.
  • Climate Change: Alterations in weather patterns and habitat conditions due to climate change can impact food availability and migration patterns.


Water deer exhibit unique and complex mating behaviors, essential for the continuation of their species.

  • Breeding Season: The rut typically occurs from November to January.
  • Courtship Displays: Males engage in courtship behaviors such as vocalizations, tusk displays, and physical sparring to attract females.
  • Territoriality: During the rut, males become highly territorial and will fight rivals to maintain dominance and access to females.
  • Gestation and Birth: After a gestation period of about 6 to 7 months, females give birth to one to three fawns, usually in May or June. Fawns are hidden in dense vegetation for protection and are weaned by the age of 3 to 4 months.

How They Communicate

Water deer use various methods to communicate with each other, particularly during mating and social interactions.


  • Barks and Grunts: Used to communicate alarm, establish dominance, and maintain contact within groups.
  • Bleats: Fawns emit high-pitched bleats to communicate with their mothers.

Body Language:

  • Posturing: Males use body postures, such as raised hackles, tail positioning, and ear movements, to convey aggression, submission, or readiness to mate.
  • Tusk Displays: Males use tusk displays and sparring to establish dominance and attract mates.

Chemical Signals:

  • Scent Marking: They use scent glands located on their legs and face to mark territory and signal reproductive status.
