Turtle
A turtle is a reptile with a hard shell that protects its body. Turtles have lived on Earth for over 200 million years.
What is it?
A turtle is a reptile that has a hard shell made of bone and keratin. The shell is part of its skeleton and protects its body. Turtles can pull their head and legs inside the shell for safety. They are cold-blooded and lay eggs on land.
How old?
Turtles are very old animals. They first appeared during the Triassic period, over 200 million years ago. That means turtles lived alongside dinosaurs! They have survived many changes on Earth.
What was it like?
Turtles live in many places: oceans, rivers, ponds, and forests. Their shells have colors and patterns that help them hide from predators. Some turtles, like the Eastern box turtle, have bright yellow patterns on a dark shell. They eat plants, insects, and small animals.
Why does it matter?
Turtles are important for their ecosystems. They help spread seeds and keep water clean. Many turtles are endangered because of habitat loss and pollution. Protecting turtles helps protect the environment.
