Devil In the Dark SEASON 1, EPISODE 25
Wiki Entry:

I hate to be repetitive, but a classic. Well-written, acted, good story, though the ecologist in me lols as a creature with a 50,000 year life cycle. That's a SLLLOOOOW evolutionary rate for what turns out to be a highly advanced species.
Side note: Shatner's father died during the making of this one. He talks about it a fair bit in Star Trek Memories, if anyone is interested.
