Log entry recordings of this mission are transcribed by Alan Dean Foster at the Galactic Historical Archives on S. Monicus I.



This is the eighth of Alan Dean Foster's TAS adaptation collections which have been reprinted a number of times, often in omnibuses with other Star Trek Log books. Most recently in 2006 by Del Rey Books, an imprint of the original Ballantine Books publishers, as part of Star Trek's 40th Anniversary celebrations.

While the episode itself mentions stardate 5501.2, the novelization states a date range of 5537.1 to 5537.2, and the dates mentioned in log entry occurrences are altered accordingly.

The episode ends with the crew leaving the Lactran zoo with the Ariel captives returning to their ship. The novelization continues the story, however, with the Enterprise helping the Lactrans find an escaped animal.
