💡 Everyday Comparisons for Size, Mass & Speed

💡 Its maximum weight of 2.8 g is about 1/3 of a single Korean 500-won coin (7.7 g), and its maximum body length of 5.1 cm is about 2 times the diameter of a Korean 500-won coin (about 2.65 cm) (Comparison).
💡 In Korea it has been collected only on high mountains such as Mount Odae and Mount Seorak, making it a tiny inhabitant of high mountain forest trails.

📖 1. Overview

The Eurasian Least Shrew is a shrew introduced by the National List of Species of Korea as "the smallest mammal in the world." It lives in northern Eurasia, Sakhalin, the Kuril Islands, and Hokkaido, Japan.

🦴 2. Anatomy & Morphology

Its head-and-body length is 44–51 mm, its tail length is 31–37 mm, and its weight is 1.7–2.8 g. In summer its back is dark brown, its belly is silvery gray, and its tail is dark brown above and pale brown below.

🔍 3. Ecology & Behavior

Within shrew communities it is competitively weak and occurs in very low numbers, and its ecology remains largely unknown.

🇰🇷 4. Connection to Korea

It is listed as "Kkomadwijwi" (Korean name) on the National List of Species of Korea and is distributed in mountains above 1,500 m in central and northern Korea, where specimens were collected on Mount Odae and Mount Seorak in 1982 and 1986.
