What is platyctenea?

Platyctenea is a class of comb jellyfish that belong to the phylum Ctenophora. They are typically small in size, ranging from a few millimeters to a few centimeters in length. Platyctenea have a unique body structure with an oval-shaped body and eight rows of comb-like cilia that they use for propulsion. They have two tentacles that they use to capture prey. Platyctenea are found in marine environments from shallow waters to the deep ocean. They are known for their bioluminescence, which they use both for communication and to attract prey. Some species of Platyctenea have been found to reproduce asexually through the process of budding. Overall, Platyctenea play an important role in marine ecosystems, serving as both predators and prey.
