Persian Ratsnake is 70 to 90 cm (up to 120 cm) long and for many years was considered a subspecies of Elaphe longissima. It was granted full species status in 1984, Nilson and Andrew.
It has a clutch of 4-8 eggs hatch after 45-55 days of incubation and a hibernation period of 2-3 months is recommended. Males seem to grow larger than females.
The validity of some genera is debatable but for the purpose of this article a more liberal taxonomic stance will be taken.
The New World rat snakes consist of the genera Bogertophis (Trans Pecos and Baja rat snakes), Pantherophis (Corn snakes, Fox snakes and American rat snakes), Pseudelaphe (Central American rat snake) and Senticola (Green rat snake).
The Genera Elaphe, Euprepiophis, Oreophis, Orthriophis, Rhinechis, and Zamenis constitute Old-World rat snakes.
