Typically measuring between 90 and 180 cm, it can sometimes reach up to 275 cm. This snake is often mistaken for a rattlesnake due to its defensive behavior, which includes hissing and tail rattling. It inhabits various environments, from grasslands to sparse forests, and plays a crucial role in controlling rodent populations. Although it may seem intimidating, it is harmless to humans and contributes to ecological balance.

The Galápagos tortoise is an iconic species of the Galápagos Islands, famous for its massive size, reaching sometimes more than 1.5 meters in length. These tortoises primarily live on the volcanic islands of the archipelago, feeding on vegetation, cactus, and fallen fruits. It is a solitary species that can live for over 100 years. While not immediately endangered, it remains threatened by the introduction of non-native species and the destruction of its natural habitat.

The Greek tortoise is a terrestrial species of tortoise native to the Mediterranean regions, particularly Greece, Turkey, and neighboring countries. It is easily recognized by its light brown to yellow shell, often marked with black patterns. The Greek tortoise is herbivorous, feeding primarily on plants, flowers, and vegetables.
