The Vietnamese mouse deer is an elusive creature, found only in the dense forests of Vietnam. It's a small animal, measuring around 40-50 cm in length, and weighing between 3-5 kg.
These deer are herbivores, feeding on leaves, fruits, and flowers. They're solitary animals, only coming together during the mating season.
The Vietnamese mouse deer is listed as Vulnerable on the IUCN Red List, due to habitat loss and fragmentation.
Classification
The Vietnam mouse-deer is a fascinating creature, and understanding its classification can help us appreciate its uniqueness. It belongs to the family Tragulidae.
The Tragulidae family is part of the larger group of even-toed ungulates, which also includes deer, goats, and cattle. Specifically, Tragulidae is a family of small, mouse-like deer that are native to Southeast Asia.
The Vietnam mouse-deer was first described as a subspecies of the greater mouse-deer (T. napu) in 1910, but it was later reclassified as an independent species in 2004. This reclassification was based on the fact that it more closely resembles the lesser mouse-deer (T. kanchil) than the greater mouse-deer.
Here's a simplified breakdown of the Vietnam mouse-deer's classification:
The Vietnam mouse-deer's classification is a reflection of its unique characteristics and its place within the larger group of even-toed ungulates.
Conservation Status
The conservation status of the Vietnamese mouse deer is a pressing concern. It's been listed as Data Deficient by the International Union for Conservation of Nature and Natural Resources (IUCN) since 2008 due to a lack of survey data or ecological cues.
Heavy deforestation and hunting pressure have emerged as major threats to chevrotains in the Gia Lai Province, where the species was last spotted in 1990. This has put the Vietnamese mouse deer at severe risk of extinction.
The species was not reported for 80 years after Thomas obtained four specimens from Nha Trang in 1910, sparking concerns about its survival. No significant measures were taken to assess the status of the Vietnamese mouse deer during this time.
Fortunately, a study published in 2019 confirmed the presence of the Vietnamese mouse deer in dry low-lying forests on the southern coast of Vietnam. Researchers used camera traps to capture images of the species, which can be identified by their characteristic double-tone coloration and throat markings.
The Vietnamese mouse deer was listed among the 25 "most wanted lost" species by Global Wildlife Conservation's Search for Lost Species initiative. This highlights the urgent need for conservation efforts to protect the species and its habitat.
Physical Description
The Vietnam mouse-deer has a distinctive physical appearance.
Its coat is rough and reddish-brown in color, with big ears that match the same color.
The throat features white and dark reddish-brown marks, a stark contrast to the rest of its body.
A prominent silver line runs down its back, giving it the name "silver-backed".
Its head-and-body length is approximately 48 cm, or 19 inches.
The tail is relatively short, measuring around 5 cm, or 2 inches, in length.
The upper part of the tail is grey, while the lower part is white, and it becomes more reddish-brown towards the tip, which is white.
The fur on the back is shabrack-like and dense, with white hair tips.
The neck and shoulders are more brown, with less dense fur, and the fur on the neck is coarser and less prickly than in the lesser mouse-deer.
The Vietnam mouse-deer lacks the dark markings along the flanks and the middle portion of the underparts visible in the lesser mouse-deer.

Habitat and Behavior
The Vietnam mouse-deer is primarily active during the day, making it a diurnal animal. This is based on camera-trap evidence from 2019.
These adorable creatures are often found alone or in pairs, suggesting a somewhat solitary lifestyle. However, they do sometimes coexist with other mouse-deer species in the same area.
The Vietnam mouse-deer can be found in various habitats, including dry lowland forests and semi-deciduous tropical forests. The 2019 study observed them in a dry lowland forest near the southern coast of Vietnam.
Elusive Spotted After 30 Years
The elusive silver-backed chevrotain, also known as the Vietnamese mouse-deer, has been spotted for the first time in nearly three decades in southern Vietnam.
This tiny creature, weighing less than 10 pounds, has a silver sheen on its back and two tiny fangs, making it the world's smallest ungulate.
Researchers captured nearly 2,000 images of a handful of these mysterious mammals using over two dozen camera traps in the wild.
The rediscovery of the silver-backed chevrotain provides big hope for the conservation of biodiversity, especially threatened species, in Vietnam, according to Hoang Minh Duc, head of the Southern Institute of Ecology's Department of Zoology.
Scientists will begin new camera trap surveys in two additional areas to determine how large the population is and better understand threats to its survival.
Ecology and Habitat
The Vietnam mouse-deer is a diurnal animal, meaning it's active mainly during the day. It's also known to stay solitary or form pairs.
In the wild, these creatures can be found in low-lying areas of semi-deciduous tropical forest, where they coexist with other lesser mouse-deer species.
A 2019 camera-trap study observed the Vietnam mouse-deer in dry lowland forest near the southern coast of Vietnam.
Here are some key facts about the Vietnam mouse-deer's habitat:
- They inhabit low-lying areas of semi-deciduous tropical forest.
- Their habitat includes dry lowland forest near the southern coast of Vietnam.
- They coexist with other lesser mouse-deer species in the same area.
Photography
The Vietnamese mouse deer is a fascinating creature, and capturing its unique beauty through photography can be a thrilling experience. They are most active at dawn and dusk, making these times ideal for snapping photos.
Their shy nature means they can be difficult to approach, so patience and stealth are key when trying to get a shot.
The forest habitat of the Vietnamese mouse deer provides a lush and vibrant backdrop for photos, with dense foliage and exotic flowers adding visual interest.
A telephoto lens can be useful for capturing images of these small deer without disturbing them, allowing you to get up close and personal without scaring them off.
