ABOUT REPTILES

Reptiles...

  • Are vertebrates. They have an internal bony skeleton.
  • Are cold-blooded. They cannot maintain their body temperature by internal means.
  • Have a dry, scaly skin or a shell.
  • Lay eggs with a tough outer shell, or have live birth. The eggs have an internal membrane called the amnion, which helps protect the developing embryo from injury and drying out. In some species of snakes, the eggs hatch internally and the young are born live
  • Lay their eggs on land.
  • Have claws on their toes (except snakes).

Currently, there are about 6,500 recognized species of reptiles in the world, divided into 5 living orders. Within Kansas, 67 species are recorded from 16 families in 3 orders.

Classification of living organisms has undergone a profound revolution within the last thirty years due to the advent of DNA analysis and the new taxonomic discipline of cladistics, which does not necessarily use the classical Linnean hierarchy (Kingdom-Phylum-Class-Order-Family-Genus-Species) to sort out how creatures are related to each other.  The position of turtles, for instance, is a contentious issue currently, and crocodiles have been found to have more in common genetically with birds than with lizards.

THE ORNATE BOX TURTLE
