Question

Quizplus · Accepted Answer

Members of the phylum Cnidaria, such as jellyfish and sea anemones, coordinate movements through a noncentralized nerve set called a nerve net. They lack a centralized brain, but their nerve net allows for basic responses to stimuli. They do have muscle-like cells called cnidocytes, but they do not have true muscle tissue, so they are not capable of complex locomotion. While some members of the phylum Cnidaria are filter feeders, many are also carnivorous and capture prey with their stinging cells. They have a simple digestive system with a single opening, so they do not have a complete alimentary canal.
