The Four-Lined Snake, elaphe quatuorlineata, is one of the largest European snake species, known for its distinctive pattern and coloration. Adults can reach impressive lengths of up to 2 meters (about 6.5 feet), making them formidable predators in their natural habitats. Their name derives from the four dark stripes that run longitudinally down their yellowish or cream-colored body, starting from the head and fading towards the tail. This striking appearance not only provides camouflage among the grasses and low vegetation but also makes them easily recognizable.

| Population: | Not precisely quantified; considered Near Threatened due to habitat loss and fragmentation |

Native to Southern Europe and parts of the Balkans, the Four-Lined Snake prefers habitats with ample sun exposure such as open woodlands, forest edges, and grasslands. These snakes are adept climbers and swimmers, but they spend much of their time on the ground, hunting and basking in the sun. They are diurnal, most active during the day when they hunt for their prey.
The diet of the Four-Lined Snake primarily consists of small mammals, birds, and occasionally eggs, which they overpower with their strength and constrict before consumption. This diet reflects their role as apex predators within their ecosystem, controlling the populations of their prey species and maintaining the ecological balance.
Reproduction for the Four-Lined Snake occurs in the spring, with females laying clutches of 5 to 15 eggs in warm, humid locations such as compost heaps or under rocks. The eggs incubate for approximately two to three months before hatching. The young snakes are independent from birth, equipped with the instincts and abilities needed for survival in the wild.
The Four-Lined Snake is considered Near Threatened due to habitat loss, agricultural expansion, and human persecution. Their habitats are increasingly fragmented by agricultural and urban development, which not only reduces their living space but also their access to prey. Conservation efforts for the Four-Lined Snake include habitat protection, research to better understand their ecological needs, and efforts to mitigate human-wildlife conflict. Preserving the populations of the Four-Lined Snake is crucial for maintaining the biodiversity and ecological health of their habitats.

The Four-Lined Snake is a non-venomous snake native to southern Europe.
It is named for the distinctive four dark longitudinal stripes running down its body. This snake can grow quite large, reaching lengths of up to 7 feet. Despite its size, the Four-Lined Snake is shy and primarily feeds on small mammals and birds.



The Siberian Pit Viper, gloydius halys, is a venomous snake native to the mountainous regions and forests of Eastern Europe and Asia, extending from Eastern Russia through Mongolia to Northern China and Korea.

The Eastern Coral Snake, micrurus fulvius, is a highly venomous snake native to the southeastern United States. Characterized by its distinctive color pattern of black, yellow, and red bands, this slender snake can reach lengths of up to 30 inches (76 cm), though most are smaller. The vivid bands serve

The Yellow-bellied Slider is a medium-sized freshwater turtle, easily recognized by its smooth, domed carapace colored in dark greens and browns, and its striking, bright yellow plastron that stands out when basking. Its streamlined body, webbed feet, and slightly elongated head are perfectly adapted for an aquatic lifestyle. The overall

The Green Iguana, iguana iguana, is a large, arboreal lizard native to Central and South America. Recognizable by its vibrant green scales, this reptile can grow up to 2 meters in length, including its tail, which it uses as a defense mechanism against predators. The Green Iguana has a row
