Chrysaora quinquecirrha

Chrysaora quinquecirrha, commonly known as the Atlantic sea nettle or East Coast sea nettle, is a species of jellyfish that inhabits the Atlantic coast of the United States. Historically, it was confused with several Chrysaora species, resulting in incorrect reports of its distribution.

Description

The Atlantic sea nettle is a bell-shaped invertebrate, usually semi-transparent and with small white dots and reddish-brown stripes. Adult nettles may reach 30 cm in bell diameter. The long, slender tentacles can reach up to 5 feet in length.

Distribution and habitat

Chrysaora quinquecirrha is found along the coast of the Atlantic Ocean, from Massachusetts to Brazil. It is particularly prevalent in the Chesapeake Bay and other estuaries. The species prefers warmer water temperatures and salinities of 10 to 26 ppt.

Life cycle

The life cycle of Chrysaora quinquecirrha includes both asexual and sexual reproduction. The asexual phase occurs when the polyp form produces clones of itself, which eventually become free-swimming medusae. The sexual phase occurs when the medusae reproduce to create a planula, which settles onto a hard surface and grows into a new polyp.

Diet

The Atlantic sea nettle is a carnivorous predator. Its diet consists primarily of zooplankton, small fish, and other jellyfish. It uses its long, stinging tentacles to capture and immobilize its prey.

Human interaction

While the sting of Chrysaora quinquecirrha is not typically dangerous to humans, it can cause a painful rash. In some cases, allergic reactions can occur, leading to more serious health issues.

Conservation

The population trends of Chrysaora quinquecirrha are currently unknown. However, changes in water temperature and salinity due to climate change could potentially impact their distribution and abundance.
