Egg-yolk Jelly
Phacellophora camtschaticaAlso known as Fried Egg Jellyfish, Egg Yolk Jellyfish, Fried Egg Jelly
Egg-yolk jellies drift through cool pelagic waters propelled by slow, rhythmic bell contractions that trail clusters of fine, stinging tentacles. Small juvenile crustaceans and larval fish routinely seek refuge beneath their broad bells, riding safely across open oceanic expanses while hitchhiking or nibbling on food scraps. These large cnidarians prey heavily on other gelatinous zooplankton, acting as specialized top carnivores in temperate pelagic food webs.

Interaction riskVery high
- Low
- Moderate
- High
- Very high
- Why interaction risk is very high
- Nematocysts deliver a mild sting that can irritate skin; avoid touching tentacles while swimming or beachcombing.
- Why it is dangerous
- Tentacles bear nematocysts that inject cnidarian venom, causing mild local skin irritation, burning sensations, and redness.
- How to recognize a risky encounter
- Recognizable by the distinct pale, translucent bell housing a central bright yellow mound like an egg yolk.
- What to do
- Give trailing tentacles plenty of clearance in the water; rinse accidental stings with saltwater and avoid rubbing the site.
Responsible observation
- Snorkeling: Keep a generous distance of several meters to avoid trailing tentacles that drift far behind the bell.
- Beachcombing: Never touch stranded jellies with bare hands, as nematocysts can still discharge when dried or dead.
