Shortridge's Mouse (Mus shortridgei)
HB:130,. T:71; HF:20.5; E; 18; W:34g
The largest mouse in Thailand, spiny, pale brownish grey above, white beneath with grey bases and white feet. The tail is lead covered or bi coloured , shorter than the head plus body. It as 46 chromosomes including a metacentric pair. You will be in for a surprise if you try to pick this mouse up by the tail as it is the common procedure as the entire tail integument slips off as id specifically greased. A constriction at its base marks the point of release. This is a protective device to foil predators. Another structural peculiarity is the large skin, lose and big enough to hold 2 bodies as can be seen when this gentle animal allows itself to be picked up by the scruff of the neck. The young are NOT spiny, but they have much larger ears than Mus cervicolor in the same habitat.
This species has a genuinely fragmented distribution in
mainland Southeast Asia and is recorded in Myanmar,
Thailand, South West
Cambodia, central Lao PDR, and North West Vietnam (Musser and Carleton 2005).
Cambodia; Lao People's Democratic Republic; Myanmar; Thailand; Vietnam
Although patchily distributed, it can be locally abundant.
Population Trend: Stable
Habitat and Ecology:
It is found in dry grass and pygmy bamboo in dry dipterocarp
forest (Marshall 1977). It is tolerant of habitat disturbance, although they
require forest cover. It shares this habitat with Mus cervicolor popacus
and Rattus surifer. In captivity they do not burrow in the sod and have
instead built a nest and raised their young in a bamboo tube
There are currently no major threats.
It is present in several protected areas across its range.
