Habitat & Fossil Locality

Tropical to temperate coastal waters and brackish waters, from the surface to depths of 200–1,000 m

💡 Everyday Comparisons for Size, Mass & Speed

💡 A bell diameter of 35 cm is slightly larger than the long side of an A4 sheet of paper (29.7 cm) (Comparison).
💡 When mass blooms occur in Korean waters in summer, the Ministry of Oceans and Fisheries issues advisory alerts, as it is known to interfere with fishers' net operations (2024 press release).

📖 1. Overview

The moon jellyfish is a round, transparent jellyfish living in coastal waters worldwide, with four horseshoe-shaped bluish gonads visible inside its bell.

🦴 2. Anatomy & Morphology

Its transparent bell is 10–35 cm in diameter, with 4 oral arms beneath it and short tentacles 1–5 cm long along the bell margin.

🔍 3. Ecology & Behavior

It feeds on plankton, copepods, bivalve eggs, fish eggs, and small jellyfish caught on its bell and tentacles, and larvae (ephyrae) that bud off from polyps grow into adult medusae.

🇰🇷 4. Connection to Korea

A jellyfish native to Korea, its venom is mild, but mass blooms damage fishing gear and disrupt fishing operations; Korea's Ministry of Oceans and Fisheries issues an advisory-level alert at a threshold of 5 adults per 100 ㎡.
