Unidentified Life Form 19 are a small flying creature, which produces a white light, native to Dark Aether. It is "summoned" by the Mutated Emperor Ing to both provide a minor barrier and to also feed upon. They appear to be the opposite of the Nightbarbs that can also be summoned. They fly in swarms, and if shot at will scatter, letting out a shriek.
- In the official Metroid Prime 2: Echoes strategy guide, they are described as "white squiggly things".
