I have had an Aldabra tortoise with a shell deformity (previous owner)for about 10 years and estimate it to be have been between 2-4 years old when i got it. Anyhow I know it is not uncommon for one to stretch out of its shell when it is touched. Although it may seem that it is somewhat enjoying the attention I question this. Is it trying to make itself bigger to ward off predators or attackers? What is the deal with the stretch? Anyone got an idea?
