Reptiles may come to recognize you and acclimate to your care, but they will never bond with you like a mammal would. However, it isn’t just because they are cold blooded. It has more to do with what is in their brain from birth than the temperature of their blood.
Before you take on turtle or tortoise care, it's best to research both animals since there are very distinct differences between these two types of reptiles. Reptiles Magazine is probably one of the best places to start learning about turtles and tortoises. As a rule, tortoises are land-dwelling, while turtles are marine.
All tortoises are turtles but not all turtles are tortoises. Although both belong to the order Testudines or Chelonia (reptiles whose bodies are attached to a shell), turtles are very different than the land-loving animal we call a tortoise.
