süvamerevöötlased

Süvamerevöötlased are a group of marine invertebrates belonging to the phylum Ctenophora, commonly known as comb jellies. These gelatinous creatures inhabit the deep ocean and are characterized by their eight rows of cilia, or comb plates, which they use for locomotion. These comb plates refract light, creating a shimmering, iridescent effect often referred to as "ctene fluorescence."

Unlike jellyfish, süvamerevöötlased do not possess stinging cells. Instead, many species capture prey using sticky tentacles or a muscular pharynx. Their diet typically consists of plankton, small crustaceans, and other small marine organisms. They are found in all the world's oceans, from polar to tropical waters, and at depths ranging from the surface to the abyssal zone.

Reproduction in süvamerevöötlased is primarily sexual, with most species being hermaphroditic, possessing both male and female reproductive organs. They release sperm and eggs into the water column for external fertilization. The larval stages are planktonic and eventually settle to the deep-sea environment.

Süvamerevöötlased play a role in the deep-sea ecosystem, acting as both predators and prey. Their bioluminescence, found in some species, is thought to be used for communication, defense, or attracting prey. The diversity within süvamerevöötlased is significant, with over 100 described species, though many more are likely yet to be discovered in the vastness of the deep ocean. Their fragile nature and the challenges of studying their deep-sea habitat make them a fascinating and often elusive subject of marine biology research.
