The Galapagos tortoise is one of the largest tortoise species in the world, native to the Galapagos Islands. These tortoises can weigh over 500 pounds and live for more than 100 years. They have a distinctive dome-shaped shell that varies among different islands, allowing them to adapt to their specific environments. Galapagos tortoises are herbivores, primarily feeding on grasses, leaves, and fruits. They play a crucial role in their ecosystem by helping to disperse seeds and maintain vegetation. Due to habitat loss and hunting, their populations have declined, leading to conservation efforts to protect these unique reptiles.
