Israel's Nonvenomous Coin-Marked Snake Thrives Despite Habitat Loss
The coin-marked snake, common in Israel and named for the coin-like spots on its back, is often mistaken for the venomous viper due to its similar appearance. However, it is a harmless, nonvenomous species that preys on various small vertebrates and is active mainly at night. Aviaad Bar, a reptile ecology expert from Ben-Gurion University, explains that this snake inhabits Mediterranean habitats from Beersheba northward to the Hermon mountains and the Lebanese border, often found near human settlements, especially rural areas.
Unlike many snakes, the coin-marked snake remains active during winter, although less so than in warmer seasons. It is an excellent climber, capable of scaling stone walls and vegetation, sometimes entering bird or rodent cages to prey on pets. Ecologically, it serves as a meso-predator, controlling populations of rodents, lizards, and birds, while also being prey for larger predators like birds of prey and mammals.
The main threat to the coin-marked snake is habitat loss due to urban expansion and shrinking open spaces, which is causing population declines. Although not currently endangered, ongoing habitat reduction could place it at risk. Climate change poses less immediate danger due to the snake's adaptability to diverse habitats and climates.
Research on this species is challenged by its elusive nature and variable activity patterns, but citizen science and digital reporting have improved data collection. There are no specific conservation programs for the coin-marked snake yet, but education efforts are increasing public awareness and appreciation. All reptiles in Israel, including this snake, are legally protected, and authorized snake catchers assist with safe removal from residential areas.
Despite being nonvenomous, bites can cause local swelling and pain, so avoiding unnecessary contact and seeking professional help if bitten is advised. The snake plays a vital role in pest control and ecosystem balance, highlighting the importance of coexistence and habitat preservation.
