Fallacy: Tortoises will come out of their shell if they are frightened

Tortoises and turtles will come out of their shell if frightened. This is not true. This is a fallacy.

Actually, the reverse is true. Tortoises pull their head and feet into their shell so that predators cannot harm or eat them. They are too slow to run away, so hiding in their shell is their way of protecting themselves.

Chelonians – hidden neck or side neck?

Tortoises and turtles are called Chelonia.

In the order Testudines (tortoise-like or turtle-like), there are two suborders: Cryptodira (hidden neck) and Pleurodira (side neck).

Cryptodira means that the chelonians pull their neck right into their shell—most chelonians are in this category. Their necks go in and out.

Pleurodira means that the chelonians tuck their neck sideways under their shell.

Tortoises and Turtles: Flat shell or domed shell?

What is the difference between flat-shelled or dome-shelled tortoises and turtles?

The tortoise has a domed shell. The tortoise lives on land. The domed shell is heavy and acts like a shield or armour to protect them from predators.

The turtle has a flat shell. The turtle lives in water. Flat shells are lighter and better for swimming in water.

The terrapin has a flat shell. The terrapin lives partly on land and partly in the water.
