Chrysaora Quinquecirrha, commonly known as the sea nettle, is a species of jellyfish found along the East Coast of North and South America. Some synonyms for Chrysaora Quinquecirrha include the Atlantic sea nettle, the eastern sea nettle, and the East Coast sea nettle. The sea nettle is recognizable by its semi-transparent, bell-shaped body and long tentacles that trail behind it. Its sting can be painful and potentially harmful to humans, making it important to exercise caution when swimming in areas where this species is present. Despite its potential dangers, the sea nettle plays an important role in the ocean's ecosystem as both predator and prey.
