Temperature will determine if a tortoise will become male or female
As a reptile species, the surrounding temperature can affect whether fertilised tortoise eggs are born male or female. When the weather is hotter it’s been logged that more females are born, especially during the warm El Niño current, which affects the Galápagos.
Turtle or tortoise?
The biggest difference between the two is that tortoises live entirely on land. The physical difference between the shell-dwelling duo is that tortoises have stumpy legs while turtle legs have developed into flippers, enabling them to swim.
The shell is 60 different bones
The most iconic feature of the tortoise, the shell is made up of 60 different bones, all of which are connected to one another. The top of the shell is called a carapace, while the underside is called a plastron.
Slow and steady
Famed for their lack of speed, tortoises can cover large distances – up to 6.4 kilometres (four miles) every day.
As well as weighing over 200 kilograms (440 pounds), an adult Galápagos tortoise can reach over 1.2 metres (four feet) in length.
