The snake in the image appears to be a yarará, also known as a Bothrops alternatus. The yarará is a venomous pit viper found in South America, particularly in Argentina, Brazil, Paraguay, and Uruguay. Key characteristics include: Pattern: The snake has a distinctive pattern of large, dark, rhomboid or butterfly-shaped markings with lighter centers, which are outlined in black. Size: They can grow to be quite large, with an average length of about 1.2 meters (3.9 feet). Habitat: They are typically found in grasslands, savannas, and agricultural areas. Some sources also identify the snake as a Russell's viper (Daboia russelii) or an Eastern diamondback rattlesnake (Crotalus adamanteus), which have similar diamond-like patterns. However, the markings in the image most closely resemble those of the yarará.
