Turtles! These lovely animals, are adorable marine reptiles, most often born on the beaches of Florida or on the Mexican Atlantic coast. They the swim to Madeira when about 1 year old, and only when over 15 to 30 years old do they decide to go back to the american coastline to spend their loast days. Juvenile turtles generally measure between 15.5 and 72.2 centimetres, but can grow to more than one metre long! They have a large head relative to the rest of their bodies and usually stay on the surface to warm up and feed.
