berguna untuk diketahui

Fakta

Some scientists think the clinging jellyfish may be a group of closely related species, because its sting and body shape vary from place to place.1

The jellyfish appear once the water warms to about 17 to 18 °C, so they follow a yearly pattern and sometimes appear in large numbers at once.1

The medusa (jellyfish) stage usually lasts no more than three months, but the polyp stage can last for years.1

Polyps can split into several new polyps by budding.1

In Europe, the species is non-native and has been found in the Mediterranean and along the Atlantic coast from Portugal to Norway and Sweden.1

Pemecah mitos

Mitos: The clinging jellyfish is harmless everywhere.

Hakikat: Its sting is harmless off the northeast Pacific coast of North America, but it can be strong and dangerous in East Asia, Europe and the Atlantic coast of the United States.1
