Habitat & Fossil Locality

Shallow, slow-moving sandy bottoms of the Geumgang River system

💡 Everyday Comparisons for Size, Mass & Speed

💡 Its body length of 8.5 cm is almost the same as the long side of a credit card (about 8.56 cm) (Comparison).
💡 Because it lives buried in sandy bottoms, the National List of Species of Korea notes that its population has declined sharply due to habitat destruction from river-bottom construction.

#미호종개#Cobitis choii

📖 1. Overview

Choi's spiny loach is a small freshwater loach found only in the Geumgang River system in Korea, living buried in sand.

🦴 2. Anatomy & Morphology

Its body is long and slightly flattened from side to side, with a pointed snout and a small mouth on the underside. A single row of brown spots runs along the lower side of its pale yellow body.

🔍 3. Ecology & Behavior

It feeds on small invertebrates in the sand such as midge larvae, and spawns in June and July. One-year-old males develop a bony plate (lamina circularis) on the pectoral fin, distinguishing them from females.

🇰🇷 4. Connection to Korea

It is a Class I endangered wildlife (Korea) species and was designated as a Natural Monument (Korea) on March 17, 2005; it is a Korean endemic living only in the Geumgang River system and has nearly disappeared from Mihocheon Stream, where it was first discovered.
