Do Turtles and Tortoises Have Exoskeletons?
Turtles and tortoises are fascinating reptiles that possess unique physical characteristics, including a protective outer shell. This shell is often referred to as an exoskeleton, but this is not entirely accurate.
Exoskeletons are external structures that support and protect the body of invertebrates, such as insects and crustaceans. They are composed of a tough, organic material called chitin.
In contrast, turtles and tortoises have shells that are composed of bone covered by scales made of keratin. Keratin is the same protein found in human fingernails and hair. These shells are not external to the body, but rather form an integral part of the animal's skeletal system.
Therefore, while turtles and tortoises have hard, protective shells that provide support and protection, these shells are not true exoskeletons.
