Galapagos Tortoise at Chester Zoo
I think this is a Galapagos Tortoise but I am not 100% sure... it could well be some sort of turtle. I know Chester Zoo has this kinda of Tortoise and I am pretty sure turtles live primarily in water and have webbed feet. These guys were in a sandy dry enclosure and look way to old and slow to swim, they are pretty damn cool tho :)
Random fact: The longest ever recorded lifespan of a Galapagos Tortoise is 152 years !
