Small Mammals of  Southeast Asia
 

Southeast Asia supports a huge diversity of small mammals which play an important role as seed dispersers in the regions forests. They are also a key link in the food chain, with many species preying on insects and other invertebrates, whilst themselves being preyed upon by larger predators. By far the largest groups are the rodents, which includes squirrels, murids (rats, mice etc.) and porcupines. The most remarkable of the group are the flying squirrels - these elusive, nocturnal creatures glide effortlessly from tree to tree by virtue of their patagium, a broad flap of skin which stretches between each limb, but leaves the tail free for balance.

Other small mammals include a variety of shrews and gymnures, which are rarely seen, and treeshrews which, to the untrained eye, look rather like squirrels.

 
 


Moles, Shrews, Gymnures etc. (Eulipotyphla) and Treeshrews (Scandentia)

  Short-tailed Gymnure
Hylomys suillus
  Common Treeshrew
Tupaia glis 
   
   
                 


Porcupines  (Rodentia, Hystricidae)   Porcupines have evolved sharp, elongated quills for defence, which are actually modified hairs.  In Southeast Asia these are rarely seen, nocturnal mammals, however they may be locally quite common in some forests.  Globally 29 species are recognised, of which 7 occur in Southeast Asia.  Examples :
 

 
           
Brush-tailed Porcupine
Atherurus macrourus
  Malayan Porcupine
Hystrix brachyura 
  Long-tailed Porcupine
Trichys fasciculata
   
   
   
   
                 


Squirrels  (Rodentia, Sciuridae)    Squirrels play a vital ecological role by consuming and dispersing seeds, which make up part of the diet of most species. Within Southeast Asia there are 82 species of squirrel, comprising 52 diurnal species, and 30 species of nocturnal, flying squirrel.  Examples :

Murids  (Rodentia, Muridae)   Rats and mice are an important part of forest ecology. They are mainly nocturnal and go largely unseen as they search the forest floor for fallen fruits, and the occasional insect to supplement their diet. Within Southeast Asia there are over 150 species of murid.  Examples :
 

                 
       
Pencil-tailed Tree Mouse
Chiropodomys gliroides
