Ctenophora

Ctenophora, commonly called comb jellies, are marine animals characterized by their transparent, jelly-like bodies and rows of hair-like structures called cilia that they use to swim. They typically have a soft, gelatinous appearance and are often bioluminescent, emitting light in the dark. Unlike jellyfish, ctenophores lack stinging tentacles, instead capturing prey with sticky cells on their bodies. They play a role in ocean ecosystems as predators of small plankton and are fascinating for their unique locomotion and light-emitting capabilities. Ctenophores are important for understanding marine biodiversity and evolutionary biology.
