2021年10月27日 · These tortoises are endemic to the Galapagos archipelago (Galapagos means tortoise in Spanish). The different islands host varied species, showcasing a large variation in the shape of their shells, from dome-shaped to saddleback shells.

Galápagos tortoises come in two types: the largest, called ‘domes’, have big, round shells, and live on the larger, wetter islands, and the smaller ‘saddlebacks’, which have a shell that curls up in front the way a saddle does, live on smaller islands that have dry vegetation.

Giant tortoises show large variation in size and shape but all species can be classed into two main shell types: domed and saddle-backed. Dome-shelled tortoises lack an upward angle to the front of their carapace (shell), restricting the extent to which they can raise their heads.

There are two types of Galápagos tortoises. The largest, with big, round shells, are called “domes.” The smaller kinds of tortoises have shells that curl up in front like a saddle and are called “saddlebacks.” Although they are massive animals, their shells are not solid.

One of the animal species most commonly associated with the Galapagos, the giant tortoise is a remarkable animal. Thought to be descended from tortoises from the continent that washed ashore in Galapagos thousands of years ago, there are now several subspecies endemic to different islands.

Galapagos tortoises have two main shell types: domed and saddle backed. The saddle-backed tortoises have saddle shaped shells with a high notch above the head, allowing their necks to reach up higher to eat vegetation off trees and bushes.
