Platyctenida, also known as benthic comb jellies, is an order of comb jellies in the class Tentaculata. Platyctenids display a generally benthic lifestyle in contrast to most ctenophores being largely pelagic. Platyctenids display widely differing morphological characteristics from their pelagic counterparts, being highly flattened on their oral-aboral axis and having lost many key traits associated with the phylum.
