The Turtle's Shell — Reading Comprehension

The turtle's shell is a remarkable feature that defines these ancient reptiles. This protective structure consists of two main parts: the carapace (top) and plastron (bottom). The carapace is made of bony plates covered by scales, forming a durable shield against predators. Turtles rely on their shells for more than just protection; it's an integral part of their skeleton, growing with them throughout their lives. When threatened, turtles can retract their head, legs, and tail into this natural fortress. Some species even have hinged shells that can close tightly, providing additional security. The shell's design varies among different turtle species, adapting to their specific habitats and lifestyles. From the streamlined shells of sea turtles to the high-domed shells of tortoises, each type serves a unique purpose in the turtle's survival strategy.
