Horta

Overview

First broadcast on 9 March 1967, the episode reveals that miners have damaged the Horta's unborn offspring. Spock communicates with her through a mind-meld.

Official production history credits Janos Prohaska's egg-dropping costume demonstration with inspiring Gene L. Coon's story, and traces the costume to Prohaska's microbe in The Outer Limits' The Probe.

Early Coon outlines proposed communication devices absent from the broadcast. These are development history, not a complete canonical lifecycle.
