Ctenophores are the “comb jellies,” well known for their beautiful bioluminescence. They appear jellyfish-like in appearance, but lack cnidocytes, the stinging cells characteristic to Cnidarians. Instead, Ctenophores have collblasts, which are adhesive cells for capturing small prey. These colorful little guys swim by manipulating currents with their eight rows of specialized ciliated cells called ctenes (comb rows). Hence the nickname comb jellies.
