Cold-blooded Gal谩pagos tortoises bask on volcanic vents to warm themselves. They weigh up to a quarter of a tonne and their heavy shell makes mating difficult. To stop the males falling off during the lengthy mating process, they have evolved a concave underside to their shell, which fits on to the convex top of the female's shell. The males call as the pair mates.
