📖 1. Overview
The ocellate spot skate (Okamejei kenojei) is a bottom-dwelling fish with a horizontally broad, diamond-shaped body living along the coasts of the West Sea, South Sea, Jeju Island, and East Sea of Korea. Large individuals are also eaten fermented.
🦴 2. Anatomy & Morphology
Its body is diamond-shaped like a stingray but rounder and wider from side to side. Its snout is relatively short, and round blotches containing dark brown spots at the base of the pectoral fins distinguish it from related species.
🔍 3. Ecology & Behavior
It feeds on invertebrates and fish on the bottom. It mates for internal fertilization and is oviparous, spawning 4–5 eggs at a time from late autumn to early spring. Its egg capsules are encased in a keratinous shell with corner horns that tangle in seaweed.
🇰🇷 4. Connection to Korea
It is listed on the National List of Species of Korea as inhabiting the West Sea, South Sea, Jeju Island, and East Sea. Large individuals are introduced as being fermented until they give off an ammonia scent before eating.
