When was the mouse deer discovered?
Chevrotains, also known as mouse-deer, are small ungulates that make up the family Tragulidae, the only members of the infraorder Tragulina. The 10 extant species are placed in three genera, but several species also are known only from fossils.
Although research into the diseases and parasites which affect the Java mouse-deer are still nascent, bovine viral diarrhea virus (BVDV 1), a pestivirus of the family flaviviridae has been detected in Java mouse-deer. Mouse-deer acquire this virus through fetal infection during early pregnancy.
The Java mouse-deer’s gestation period usually lasts 4.5 months, or 144 days. Typical litters consist of a single fawn, which resembles a miniature adult, although the tusk-like incisors prevalent in males are not visible in the young mouse-deer.
The Java mouse-deer is also known by many common names, including Javan chevrotain, Javan mousdeer, or Java Mousedeer. The taxonomic status of the Java mouse-deer is questionable, but recent craniometric analyses have begun to shed light on the taxonomic discrepancies.
The Visayan spotted deer (Rusa alfredi), also known as the “Visayan deer”, the “Philippine spotted deer” or “Prince Alfred’s deer”, is a nocturnal and endangered species of deer located primarily in the rainforests of the Visayan islands of Panay and Negros though it once roamed other islands such as Cebu, Guimaras.
“The silverback chevrotain was first discovered in the early 1900s. After that, the species went unrecorded until 1990. It’s only known from a small part of Vietnam. So, it’s not very widespread.
7 beats per second
To protect themselves and their mates or to defend their territory, mouse-deer slash rivals with their sharp, protruding canine “tusks.” It has also been observed that, when threatened, the Java mouse-deer will beat its hooves quickly against the ground, reaching speeds of up to 7 beats per second, creating a “drum …

Chevrotains, or mouse-deer, are small even-toed ungulates that make up the family Tragulidae, the only extant members of the infraorder Tragulina. The extant species are found in forests in South and Southeast Asia, with a single species, the water chevrotain, in the rainforests of Central and West Africa.
Not extinct
Chevrotain/Extinction status
Chevrotain, (family Tragulidae), also called mouse deer, any of about 10 species of small, delicately built, hoofed mammals that constitute the family Tragulidae (order Artiodactyla). Chevrotains are found in the warmer parts of Southeast Asia and India and in parts of Africa.
1910
The Vietnam mouse-deer (Tragulus versicolor), also known as the silver-backed chevrotain, is an even-toed ungulate in the family Tragulidae known only from Vietnam. It was first described in 1910 by British zoologist Oldfield Thomas, who procured four specimens from Nha Trang in Annam.
