Platyctenea represents a unique order of comb jellies within the phylum Ctenophora. Unlike most comb jellies, they are benthic, meaning they live on the seafloor. These creatures are flattened and creeping, resembling flatworms. They often have symbiotic relationships with other marine organisms. Think of them as the undercover agents of the sea, blending in with their surroundings. They are a fascinating example of adaptation within the Ctenophora.
