Least Pygmy Squirrel

Fascinating facts about the Least Pygmy Squirrel

• Within the entire rodent order, sciurids like this squirrel show a surprisingly uniform growth pattern. A study of 51 rodent species found that Sciuridae had a reduced magnitude of inter-trajectory change and less variation in allometric coefficient values compared with muroids and Ctenohystrica. This conservatism suggests that squirrels, including the least pygmy, evolve under tighter morphological constraints, which may limit how dramatically they can change shape over time.
• The species lives almost exclusively below 750 m (2,500 ft) altitude on Borneo, Sumatra and Banggi, though some populations push higher into the hills.
• Surveys across Sabah's Heart of Borneo reserves recorded 60 terrestrial mammal species. The rapid-assessment study covered 15 forest reserves over a 5-year timeframe.
• Sabah contributes 4.2 million hectares to the Heart of Borneo, a massive block of protected forest that shelters this diminutive squirrel. The study notes high poaching intensity.
