Galápagos Giant Tortoise (Chelonoidis porteri)
The world’s largest living tortoise — dome-shelled adults can top 400 kg and live well past 100 years, and they love a good mud bath to cool down and shed parasites.
Giant tortoises are resident year-round across the Galápagos archipelago; the highland wallows of Santa Cruz Island are one of the easiest places to watch them soak.
