Dolichophis caspius is the fastest and the most aggressive snake in Romania. Its bite can only be painful as it isn’t a venomous snake.
Dolichophis caspius used to be known by the name of Coluber jugularis. The present name has been accepted since 2004. [11, 15]
It can be found in Asia Minor, the Balkans, Hungary, the South and South-East of Romania, the Republic of Moldavia, Ukraine, the South of Russia (Caucasus) and the West of Kazahstan. [8, 9, 16, 18, 20]In Romania it can be often found in the South of Banat, the South of Oltenia and Muntenia, the South-East of Moldavia and in many locations in Dobrogea. [1, 3, 4, 5, 6, 7, 8, 10, 12, 16, 17, 19] Morphology. It is the fastest and the most aggressive snake in Romania and it can grow up to 2 meters. The head is elongated, separated by the neck, the snout is round, the eyes are relatively large with a round pupil and a well differentiated canthus. Maxillary teeth are not equal in length, the ones in the posterior part being longer. The tail is long and thin. The rostral is distinct, the frontal can be equal or shorter than the parietals. The nostril is situated between two plates, the preocular scale is high and it is situated on the small subocular, the temporal scales can be 2+2 or 2, 8 supralabials and two pairs of inframaxillary scales. Dorsal scales are smooth with 19 transversal rows, rarely 17 or 21. It has 160-211 ventral plates, the anal is divided and it also has 87-131 pairs of subcaudal scales. [6, 7]
The Colour on the dorsal side is brown, yellowish brown or greyish brown. The center of each scale is lighter in colour than the edges. The ventral side is yellow and the sides of the neck are sometimes yellowish orange. The colour of the juveniles’ dorsal side is brown or grey with dark spots. [6, 7]
Ecology. Dolichophis caspius is a species adapted to dry and warm areas, being found especially at the edge of the forest, near bushes, on rocky slopes. [6, 7, 8, 14] It feeds on lizards, rodents, mice and rats. [6, 7] The Caspian whipsnake is the fastest snake in Romania, it easily climbs rocks and trees. It is probably one of the most frequent victims of road traffic and deliberate killings, its natural habitat being under reduction. [13, 20]
Reproduction takes place at the end of May; the male grabs the female by the neck and puts his tail around her. They lay 5-12 eggs at the end of June or at the beginning of July. Males are larger than females and they also have a larger head and a smaller number of ventral scales (under 196). [6, 7] Birds and various meat-eating mammals can be found among their predators. 
Legislation. In Romania the species is protected by Law no.13 of 1993, by which Romania ratifies the Berne Convention (Annex II), European Directive 92/43/EEC (Annex IV) and also by Government Emergency Ordinance no. 57/2007 regarding the state of natural protected areas, the conservation of natural habitats, of the wild flora and fauna, approved with subsequent amendments and supplements (Annex IV A and IV B), being considered a community and national interest species which requires strict protection. [21, 22, 23]
According to the IUCN classification, at a global level, this species has a Least Concern status (LC), and in the Red Book of Vertebrates of Romania it is marked as vulnerable (Vu). [8, 24]
