Horta

The Horta are a silicon-based life form native to Janus VI.

In 2267, first contact between the Horta and the Federation was established by [[Captain James T. Kirk of the USS Enterprise. The miners that had colonized Janus VI had been unknowingly destroying the Horta's eggs, thus jeopardizing its 50,000-year reproductive cycle. (TOS episode: "The Devil in the Dark")

After the misunderstanding was cleared up, the remaining Horta eggs hatched, and the species began to thrive once more. By 2300 there were nearly 1,100 new Horta on Janus VI, and fifty years later there were more than 3,000. (New Worlds, New Civilizations)
