💡 Everyday Comparisons for Size, Mass & Speed
- 💡 A body length of 10 cm is shorter than a ballpoint pen (about 14 cm) (comparison).
- 💡 A maximum weight of 13.6 g is about one-quarter of a single chicken egg (about 50–60 g) (comparison).
- 💡 Because it lays its eggs inside freshwater mussels, protecting riverbed mussel habitats directly protects this fish.

📖 1. Overview
The big-striped bitterling is a bitterling inhabiting the Seomjin and Nakdong River systems, marked by a dark green stripe along the side of its body.
🦴 2. Anatomy & Morphology
The body is laterally compressed with relatively large eyes and large scales. During the spawning season, males display vivid nuptial coloration and dense breeding tubercles around the snout.
🔍 3. Ecology & Behavior
It feeds mainly on attached algae on rock surfaces and lays its eggs inside the gills of freshwater mussels (bivalves) from April to June. Males establish territories around the mussels.
🇰🇷 4. Connection to Korea
It is an Endangered Wildlife Class II species and a Korean endemic living only in parts of the Seomjin and Nakdong River systems. In the Nakdong River, it often shares habitats with Jul-napjaru (a Korean animal name).
