A platyctenean is a member of the order Platyctenea, a group of comb jellies that live on the seafloor, unlike their free-swimming relatives. These fascinating creatures are flattened and often cryptic in coloration, blending in with their surroundings. They are often found clinging to rocks or corals. They feed on small invertebrates and engage in symbiotic relationships. Imagine them as the flatworms of the comb jelly world, quietly living their lives on the ocean floor.
