If you’re learning Tagalog, fascinated by marine life, or planning a beach trip in the Philippines, the word for jellyfish is most commonly uyakoy (pronounced oo-yah-KOY, with stress on the last syllable) or diyamante ng dagat (literally “diamond of the sea,” a poetic name). In everyday conversation and markets, Filipinos often just say jellyfish (borrowed directly), but uyakoy is the authentic Tagalog term you’ll hear from fishermen, locals, and in coastal communities. Another regional name is salabay in some Visayan areas, but uyakoy is widely understood nationwide.
Jellyfish are not fish at all—they’re gelatinous zooplankton belonging to the phylum Cnidaria, famous for their translucent bells, trailing tentacles, and stinging cells (nematocysts). In Philippine seas, they range from harmless moon jellies to the occasional dangerous box jellyfish. This blog post covers pronunciation, facts about jellyfish in Philippine waters, practical example sentences, their role in culture and cuisine, and more to help you talk about uyakoy naturally.
What Is “Jellyfish” in Tagalog? Pronunciation and Basics
Uyakoy is the traditional Tagalog word for jellyfish, especially the common moon jelly (Aurelia aurita) and similar species. Diyamante ng dagat is a more descriptive, poetic name sometimes used in storytelling or tourism. Pronunciation of uyakoy is oo-yah-KOY—say it with a light glide on the “y” sound.
Jellyfish have a bell-shaped body (umbrella) and long, stinging tentacles used to capture plankton and small fish. In the Philippines, they appear seasonally, often blooming in large numbers during warmer months or after heavy rains when nutrient-rich water flows into the sea.
Fascinating Facts About Uyakoy in Philippine Waters
The Philippines is home to dozens of jellyfish species, from the harmless moon jelly (uyakoy na buwan) to the potentially dangerous box jellyfish (Chironex or Chiropsalmus species) found in some coastal areas. Massive jellyfish blooms occur in places like Manila Bay, Pangasinan, and parts of Mindanao, sometimes closing beaches temporarily.
Interestingly, jellyfish play a key role in the food web—providing food for sea turtles, certain fish, and even humans in some Asian cuisines. In the Philippines, small jellyfish are occasionally harvested for food (especially in dried or pickled form in Chinese-Filipino communities), though this is not widespread. Conservation concerns focus on blooms caused by overfishing (removing predators), pollution, and warming seas.

Uyakoy in Philippine Culture and Beach Life
Jellyfish are not a major part of traditional Filipino cuisine (unlike in some Asian countries where dried jellyfish is a delicacy), but they appear in coastal folklore as mysterious drifters. Beachgoers are very familiar with uyakoy season, when blooms can lead to temporary swimming bans or advisories.
In tourism and education, Filipinos learn about jellyfish stings (treated with vinegar to neutralize nematocysts, never rubbing or freshwater). Sea turtles are celebrated as natural predators that help control jellyfish populations. Many coastal communities hold clean-up drives to reduce plastic pollution, which jellyfish often mistake for food.
