Ciona intestinal

Ciona intestinal was the scientific name for an animal in the HMS Bounty's database.

In 2286, it was among the listings that appeared while Spock was running the Bounty's phylum search mode to confirm the similarity between the Whale Probe's call and that of humpback whales. (Star Trek IV: The Voyage Home)

In reality, Ciona intestinalis is a sea squirt, though the image appears to show a winged insect.
