In a study performed in 1971, when A. cahirinus were removed from an environment, A. russatus became nocturnal (Kronfeld et al. For species with a comparatively short lifespan and rapid turnover of generations, the captive population must be larger in order to avoid rapid loss of genetic diversity. Grants DRL 0089283, DRL 0628151, DUE 0633095, DRL 0918590, and DUE 1122742. Total length may equal 30 in (76 cm).
