Stinger fish were aquatic creatures native to the planet Sedri. They were jellyfish-like creatures with suction cups that stung upon contact. The sting was not life-threatening, but was irritating and annoying. A large number of stinger fish in one place could cause confusion and panic.[1]
Karak's renegades released a large number of stinger fish into the Fitsay marketplace as part of their raid on the city in an effort to secure coral from the Golden Sun.[1]
