The Coreeshi are an alien species first seen in the Farscape episode "I Shrink Therefore I Am." One later appears in the comic "Backyard Barbeque."
Coreeshi graft themselves into bioengineered exoskeletons and are unable to survive outside it. In the distinguished words of John Crichton, they're "crunchy on the outside, chewy on the inside." These shells serve as their body armor, complete with an array of weapons and other devices, such as comms and audio-enhancement technology. All of these are accessed from a keypad set in their forearms.
In particular, the Coreeshi are reputed for their miniaturization technology. Because of this, they are often hired as bounty hunters (including by Peacekeepers). They hold their shrunken captives in capsules located in their chest cavities.
