Reptilia Natrix maura, commonly known as the Viperine Snake or Mediterranean Water Snake, is a fascinating species that inhabits the wetlands, rivers, and ponds of the Comunidad Valenciana. Known locally as "Culebra viperina," it is a non-venomous snake that mimics the appearance and behavior of venomous vipers as a defense mechanism.

This species is characterized by its stout body and distinctive patterning, which serves as excellent camouflage against both predators and prey.

• Size: Natrix maura typically grows to a length of 60-100 cm, though some individuals can reach up to 130 cm.
• Coloration: It displays a gray or brown background with dark zigzag patterns along its back, mimicking the appearance of a viper. The ventral side tends to be a lighter color with irregular dark spots.
• Habitat: Prefers freshwater environments such as streams, rivers, ponds, and lakes. They are excellent swimmers and spend much of their time in or near the water.
• Diet: Their diet mainly consists of amphibians, fish, and small invertebrates, which they catch in the water.
• Behavior: When threatened, they may flatten their bodies and hiss to deter predators, resembling the more dangerous vipers.

While not harmful to humans, it's important to observe these snakes respectfully and from a distance to appreciate their ecological role as both predators and prey in the aquatic ecosystems of the region.
