From Halopedia, the Halo wiki
A nelosh was a long-necked, aquatic animal that was native to Janjur Qom, the San'Shyuum homeworld. The animal was allegedly weightless and had the ability to float through the air. The nelosh had coils of sorts that whipped out from its body, and tendrils that the animal used as an appendage to feel around its location. The Huragok Sluggish Drifter reminded Zo Resken of the animal, which he had read about in Mken 'Scre'ah'ben's records of Janjur Qom.
