 Drymonema 

Drymonema is a genus of true jellyfish, placed in its own family, the Drymonematidae. There are three species of the genus Drymonema that are placed in this family. These species ''Drymonema dalmatinum, Drymonema gorgo, and Drymonema larsoni are found in the Atlantic Ocean and Mediterranean Sea. ''

Species

 * Drymonema dalmatinum Haeckel, 1880
 * Drymonema gorgo F. Müller, 1883
 * Drymonema larsoni Bayha & Dawson, 2010

Drymonema larsoni "Pink Meanie"
Drymonema larsoni is a species of the class of scyphozoan jelly fish within the genus Drymonema. This "true jellyfish" is found to have vicious blooms in the northern area of the Gulf of Mexico. Drymonema larsoni get their name "pink meanie" from their predation and eating habits. The pink meanies were found to feed on the moon jellyfish (Aurelia sp.) in the northern section of the Gulf of Mexico.

Drymonema dalmatinum "Stinging cauliflower" "Purple Sea Mane"
Drymonema dalmatinum is another species of the class of scyphozoan jelly fish within the genus Drymonema. This species is found in the central part of the Atlantic Ocean and along the Mediterranean Sea. The first ever recorded Drymonema dalmatinum was off the coast of the northern Alboran Sea. The stinging cauliflower is a pale pink to golden brown coloration with a large number of clear tentacles, along with long/thin oral arms. This species of Drymonema also feeds on species of moon jellyfish such as Aurelia sp. There have been sitings in Puerto Rico in1999 of this species of Drymonema, a population bloom of these so called "purple sea manes".

Drymonema gorgo
Drymonema gorgo is another species of the class of scyphozoan jelly fish within the genus Drymonema. This species of "true jellyfish" is found in the western South Atlantic.

== Morphology ==


 * Allometric growth of the bell margin.
 * Ring shaped zone of tentacles.
 * Loss of gastric filaments with the development/ontogeny of an organism.
 * Radial symmetry
 * Lack a velum

Reproduction
The reproduction of the genus Drymonema is similar to the reproduction of all Scyphozoans. These organisms can undergo both sexual (medusa) and asexual (polyp) reproduction processes. In the case of a medusa, sexual reproduction is external, where the males release the sperm while the females release eggs into the water and they fuse. This fusion results in free swimming planula larva that eventually sinks to the bottom or finds a hard surface to attach to. Once attached the planula larva starts metamorphosis and becomes a polyp. This polyp will reproduce asexually, most commonly using budding, and producing ephryae (larval stage of Drymonema once it has detached from the scyphistoma) which mature into a medusa to begin the life cycle process over again. Scyphozoans and Drymonema species alternate between sexual and asexual reproduction stages.

Feeding

 * Translucent tentacles used for grasping and feeding.
 * Drymonema species eat an abundant amount of moon jellyfish (Aurelia sp.)
 * Food ingested and waste excreted must come out of the same opening, (no digestive tract).
