Zap-jelly

Zap-Jellies are predatory sea creatures that live in the brackish seas of the Grunt homeworld Balaho. They glow with a faint pink light. They are considered to be a delicacy among the Grunt population. The translation "Zap-Jellie" and the comparison or their apperence to High Charity may mean that this creature is similar to the Medusa cnidarians (jellyfish) that are indigenous to Earth.

They are apparently a predatory species.

Trivia

 * High Charity has been stated to look like a massive zap-jellie floating through space.
