Cydippida (Sea Gooseberries) Ctenophores are transparent, gelatinous and biradiate coelenterates. Comb jellies are undoubtedly pretty distant from humans, but, unlike the sponges, they share with us advanced features such as nerve cells, muscles and a gut.

Swims by means of plates of cilia (the combs) Reproduction mostly sexual […] From the 19th century to about ten years ago, there was general agreement that our most distant relatives are sponges. For example, the animals known as comb jellies look in many ways like true jellyfish, but are actually distant cousins. Comb jelly in an aquarium.

Conclusion. December 10, 2020 – At least nine major groups of deep-sea animals, including jellies, corals, brittle stars, squids, and fish, use the same light-emitting chemical, coelenterazine, to power their displays. wikipedia, CC BY-SA. Though comb jellies are, for the most part, of small size, at least one species, the Venus’s girdle, may attain a length of more than 1 m (3 feet).One parasitic species is only 3 mm (1 / 8 inch) in diameter.Some ctenophores live in somewhat brackish water, but all are confined to marine habitats. • Comb jellies are delicate, transparent, non-stinging predators.

Body multicellular, few tissues, some organs and organelles. Most comb jellies have eight rows of comb-like cilia that rhythmically beat, refracting light into colors, as they paddle through the water. Unlike cnidarians, with which they share several superficial similarities, they lack stinging cells. These stinging cells are called nematocysts (Neh-MAT-oh-sistz).
