Snakes, Lizards, Crocodilians, Turtles and Tortoises
A tortoises bones are throughout their body, including making up the shell.
Snakes have bones and bones are made up from cells.
The four groups of reptiles are crocodilians, lizards, snakes, and turtles, terrapins, and tortoises. Snakes have no ears or sense of hearing, and only turtles, terrapins, and tortoises have shells.
Reptiles of any sort can be eaten. Snakes have a lot of bones so be careful. Turtles and tortoises are good. If you choose to eat insects like grasshoppers cook them or you may get tapeworms.
The hip bones in snakes (and in humans) are called the pelvis.
Lizards are the most common reptile found in the desert followed by snakes, then tortoises and turtles.
Tortoises are probably about as closely related to snakes as you are to a squirrel. :) They are both reptiles (just as you and a squirrel are both mammals), but tortoises are a very old kind of reptile, and snakes are the newest kind of reptile. Snakes are more closely related to lizards--but still not all that closely related.
