epi-mesopelagic.
For Böttger-Schnack & Huys (1997, p.84) this species displays a remarkable combination of primitive and advanced character states which clearly separates it morphologically from all other known oncaeids.. perhaps the most unusual character of A. arabica is the trisetose leg 5 exopod which is clearly exposed on the body and allows for rapid identification of this species without dissection.
