Kitti's Hog-Nosed Bat

Audrey Reyes


The Bumblebee Bat is considered to be the smallest mammal in the world, weighing less than 2 grams. The reason for its name is due to its resemblance in size with the average large bumblebee. It is the sole living species of the family Craseonycteridae.

The bat has long greyish-brown fur on its back, and shorter, paler fur on its underparts. Its flat, fleshy, pig-like muzzle, along with its extremely small eyes concealed by facial hair, is the reason for its other common name of "Kitti's Hog-Nosed Bat." Their large and membranous ears, with a long and well-developed tragus, enhance their ability to pinpoint the echoes with which they navigate. Male Kitti’s hog-nosed bats possess a rounded, glandular swelling on the lower portion of the throat; this is either less prominent or completely absent in females.

Cause of it being Endangered

The cause of this species being endangered is due to the fact that air pollution is becoming more and more common in Thailand due to cement plants.

Discovered in 1974, this mammal has been disturbed by collectors and tourists ever since.

Surveys are also required to locate colonies of these bats and protect them from further human disturbance.

Craseonycteris thonglongyai

Location: Western Thailand and south-east Myanmar in Limestone Caves near the Khwae Noi River (within deciduous forests or dry evergreen)

As well as being so small, this mammal also has to deal with environmental problems.

The main threats are from burning forest areas near limestone caves, where they live

While estimated at 2,000 bats remaining in Thailand, the status in Myanmar is unknown (but surveys seem to be saying that there are more than 2,000 in Myanmar). Its extinction would not only be the loss of an incredibly unique species, but an entire branch of the evolutionary tree would vanish from our planet.

!!!¡¡!!¡!! Population rate is declining very quickly !!!!!¡!!!¡¡!!

The Kitti's hog-nosed bat has absolutely no fossil records which makes it difficult to figure out the evolution of the future species.
