💡 Everyday Comparisons for Size, Mass & Speed

💡 A body length of 6.4 cm is about two and a half times the diameter of a Korean 500-won coin (2.65 cm) (Comparison).
💡 In a study at Taeanhaean National Park, stomach contents consisted of insects, spiders, and amphipods across 8 orders and 13 families—a lizard living on small prey in coastal sandy ground.

#표범장지뱀#Eremias argus

📖 1. Overview

The Mongolia Racerunner is a small lacertid lizard living in Mongolia, northeastern China, southern Russia, and along the west coast of Korea.

🦴 2. Anatomy & Morphology

Its body (snout-to-vent length) is small at 31–64 mm. Males have longer tails and heads as well as longer forelimbs and hindlimbs than females.

🔍 3. Ecology & Behavior

Active by day, it eats insects and spiders. In the stomachs of 6 individuals caught in Taeanhaean National Park, lepidopteran insects (30.6%) and spiders (20.4%) were most abundant, and the species lays eggs.

🇰🇷 4. Connection to Korea

In Korea, it is designated as Class II endangered wildlife (Korea) and has been recorded in west-coast coastal sand dunes (such as Taean) and some mountain areas. Only 3 lacertid species live in Korea: the Mongolia Racerunner, the Amur Grass Lizard, and Jangjibaem (a Korean animal name).
