Habitat & Fossil Locality

Seafloor around Jeju Island and the South Sea coast at depths of 20–200 m (on rocks in shallower waters)

💡 Everyday Comparisons for Size, Mass & Speed

💡 Its shell has been used as an ornament and its flesh as food, and overharvesting is a cause of its population decline (National Institute of Ecology).
💡 Its maximum length of 39 cm is about 1.3 times longer than the long side of an A4 sheet of paper (29.7 cm) (Comparison).

Reference standards: coach bus ~12 m, mid-size car ~4.9 m, compact car ~1 t, basketball hoop 3.05 m, credit card 8.56 cm.

📖 1. Overview

The knobbed triton is the largest marine snail in Korea, living in the seas around Jeju Island and the South Sea coast.

🦴 2. Anatomy & Morphology

Its shell is very hard and thick, with irregular reddish-brown markings scattered over a yellowish-white background. The aperture is a large, elongated oval with a thick outer lip.

🔍 3. Ecology & Behavior

It mainly preys on starfish, and around Jeju Island it favors Ppalgangbulgasari (a Korean starfish name). Sexes are separate, fertilization is internal, and eggs are laid from December to April.

🇰🇷 4. Connection to Korea

It is designated as Class I endangered wildlife (Korea) and is distributed mainly along the coasts of Jeju Island and the South Sea. Overharvesting for food is cited as a factor in its population decline.
