Oneirodes alius is known only from the Halmahera Sea. The holotype, three non-type specimens (11.5–12 mm), and the 21-mm paratype were captured with a closing net between 575–600 m, 700–1000, and 1000–1100 m, respectively. The remaining two specimens were captured somewhere between the surface and 1200 m.
Oneirodes alius is a member of the O. schmidti-group. In addition to its unique escal morphology, O. alius appears to differ from other members of the O. schmidti-group in having fewer lower jaw teeth.
Meso- to bathypelagic.

Although unknown, males of O. alius are certainly free-living and presumed non-parasitic, as is the case with most oneirodid taxa.
Known from 7 metamorphosed females (10–38 mm).
