  3. Adult giant tube worms have no mouth or gut and rely on symbiotic bacteria for nutrition.

  4. Siphonophores blur the line between an individual and a colony; they are made of specialized zooids.

  5. Two injured Mnemiopsis leidyi comb jellies can fuse into a single entity that shares physiological functions.

  6. The mantis shrimp eye has a midband whose colour rows hold 12 types of photoreceptor, covering deep ultraviolet to far red.
