The smaller breeds of tortoise are very popular as pets. Slow-moving, easy to feed, and long-living. Many families, including mine, have kept a pet tortoise, or more than one. But that doesn’t mean to say we should keep them of course, as they are never truly domesticated.
In some countries, they are called turtles, because they are in the same animal family. As this graphic explains.
In far-flung places like the Galapagos Islands, giant tortoises can grow to an enormous size. In the past, they were hunted for their meat, and also for their shells.
I understand that they are no longer so popular as pets, and that is a good thing. Hopefully, they can be left alone to live their lives naturally.
