Indri VIII

Indri VIII was a Class L planet, last in orbit of the Indri system. It was first identified by Federation scientists around 2340. The planet was covered by deciduous vegetation until 2369, but possesses no animal life or evidence of past civilization. Indri VIII was one of the planets seeded with part of a genetic program by the ancient humanoids 4.5 billion years ago. In 2369, the Klingon Vor'cha class vessel IKS Maht-H'a collected a DNA sample from Indri VIII, then destroyed the planet's biosphere with a plasma reaction. All life on the surface was extinguished, precluding any others from collecting a sample. (TNG: "The Chase")
