Definition
A ctenophore, also known as a comb jelly, is a gelatinous marine invertebrate characterized by rows of cilia (comb-plates) used for swimming. They are found in oceans worldwide. Ctenophores are predatory, feeding on plankton and other small organisms. Imagine them as transparent, shimmering blobs drifting through the water. Unlike jellyfish, most ctenophores don't sting, but use sticky cells to capture prey.
