Chrysaora plocamia, the South American sea nettle, is a species of jellyfish from the family Pelagiidae.

[4][5] The specific epithet of C. plocamia is derived from the Ancient Greek plókamos, meaning "tress" or "braid of hair".

The South American Sea Nettle is known for its red-brown bell, long, spiraling arms, and thin tentacles.

The bell can grow to a maximum of nearly 30 inches in diameter while the trailing arms can reach 12 to 15 feet in length.

Blooms and strandings of Chrysaora plocamia are reported to occur along both Atlantic and Pacific South American coasts.

[7] Additionally theses nettles are 15% of all beachings, and cover an area of 13,000 km of coast line.

This occurs on the seafloor, or the benthos, and this type of asexual reproduction is considered to be an important indicator for population blooms.

Sexual reproduction occurs when female medusae catch sperm drifting through the ocean and fertilize eggs that it has released.

[6] The diet of the South American Sea Nettle consists primarily of a wide variety of zooplankton.

This movement is unable to resist strong currents; however, C. plocamia is adapted to be able to survive without relying on their locomotion.
