The Oniboshi lum ran was an aquatic lifeform and a subspecies of the Oniboshi lum species, native to the planet Denkir IV.

This species' name was mentioned on the chart "Evolution of Intelligent Life on Planet Denkir IV". (TNG: "The Child")

The species is mentioned merely as O. lum ran, however it appears further up the evolutionary tree from a species called Oniboshi lum. A third related species appears to be misspelled Oniobshi benten.
The name of this species is a reference to the Japanese anime and manga series Urusei Yatsura, which features aliens with the names Lum and Ran, the latter hailing from a planet called Oniboshi.
