Unknown Life Form 11 is a large life form native to the planet Phaaze. One of these life forms is seen living at the bottom of a tunnel, underground. When it senses prey, it opens up, revealing a massive jaw, ringed with large fang-like teeth, that opens up itself, revealing a smaller jaw with a ring of tentacles that appears to be made up of a substance similar to phazon. It should be noticed that it appears to expel clouds of phazon-like gas from holes around its mouth. When it captures "prey", the inner mouth engulfs it and is then pulled into the larger one, which closes shut yet remains above the ground. It is most likely a species of passive predators, waiting for potential prey to fall onto it, based upon its apparent sedentary lifestyle.

This life form is slightly similar to a hydra or sea anemone in appearance. It is also slightly similar to an enemy in the Half-Life series, the Barnacle, save for being upside-down.

Unknown Life Form 10 is a large life form native to the planet Phaaze. It has five eyes, along with a pair of claws that it uses to capture and then hold its prey as it is slowly pulled towards its giant open jaws. It was seen living in the wall of a downward tunnel, waiting for prey, such as Samus, to fall into its "lair". It is most likely a species of passive predators, waiting for potential prey to come by it, based upon its "observed" sedentary lifestyle. Its "tongue", which to appears to be an inner, secondary jaw, appears to be a weak part, and is for some unknown reason directly attached to its five eyes, since they are seen exploding as it is damaged.
