A lynar

The lynar was a harmless bat-like creature native to Celtris III. They typically lived in caves.

In 2369, Captain Jean-Luc Picard, Doctor Beverly Crusher, and Lieutenant Worf encountered a small flock of lynars on Celtris III. According to Picard, they were, "harmless" and common to Celtris III. (TNG: "Chain of Command, Part I")
