Wikipedia Meaning and Definition on 'Turtle'

Cryptodira Pleurodira and see text

Turtles are reptiles of the order Testudines (the crown group of the superorder Chelonia), characterised by a special bony or cartilaginous shell developed from their ribs that acts as a shield. "Turtle" may either refer to the Testudines as a whole, or to particular Testudines which make up a form taxon that is not monophyletic—see also sea turtle, terrapin, tortoise, and the discussion below.

The order Testudines includes both extant (living) and extinct species. The earliest known turtles date from 215 million years ago,

Like other reptiles, turtles are ectotherms—varying their internal temperature according to the ambient environment, commonly called cold-blooded. However, leatherback sea turtles have noticeably higher body temperature than surrounding water because of their high metabolic rate.

At the end of the lecture a little old lady at the back of the room got up and said 'What you have told us is rubbish. The world is really a flat plate supported on the back of a giant tortoise.'
