📖 1. Overview
The longjaw bonefish is a bonefish living along tropical coasts of the western Pacific, with an elongated, streamlined silvery-white body.
🦴 2. Anatomy & Morphology
The body is cylindrical and silvery-white, covered entirely in scales. The dorsal fin sits near the middle of the flank and the lateral line is complete.
🔍 3. Ecology & Behavior
Living along tropical coasts, it passes through a flat larval stage called a leptocephalus when young before metamorphosing into its adult form. It rarely visits coral reefs and is occasionally seen in sheltered shallow lagoons.
🇰🇷 4. Connection to Korea
It is listed on Korea's National Species List and recorded from Busan, Jeju, and Geoje.
