väiksemaletsa

Väiksemaletsa, also known as the lesser mole rat or *Spalax microphthalmus*, is a small subterranean rodent native to parts of Eastern Europe and Western Asia. This species belongs to the family Spalacidae, which comprises burrowing rodents adapted to life underground. Väiksemaletsa is primarily found in regions such as Estonia, Latvia, Lithuania, and parts of Russia, where it inhabits grasslands, meadows, and agricultural fields.

The lesser mole rat is characterized by its compact, cylindrical body, small eyes, and reduced external ears, adaptations that minimize exposure to light and reduce heat loss in its dark, underground environment. Its fur is typically dark brown or grayish, providing camouflage within the soil. Unlike many rodents, väiksemaletsa lacks visible vibrissae (whiskers), further distinguishing it from surface-dwelling relatives.

This species is a solitary and fossorial animal, spending nearly its entire life underground. It constructs extensive tunnel systems used for foraging, shelter, and reproduction. Väiksemaletsa feeds primarily on roots, tubers, and other plant material, using its strong incisors to excavate and consume food efficiently. Its diet and burrowing habits make it an important ecological engineer, influencing soil structure and plant distribution in its habitat.

Reproduction in väiksemaletsa occurs year-round, with females giving birth to litters of 2–6 offspring. The young are born blind and hairless but develop rapidly, becoming independent within a few weeks. Lifespan in the wild is typically 2–3 years, though individuals in captivity may live slightly longer.

Conservation status for väiksemaletsa is generally stable, though habitat loss due to agricultural expansion and urbanization poses potential threats. Its subterranean lifestyle makes it less visible to humans, contributing to limited public awareness and research. Studies on this species often focus on its unique adaptations to underground life, including physiological and behavioral traits that facilitate survival in a low-resource environment.
