There is only one species found in Canada, the Spiny Softshell Turtle . Squamata One of the four Orders of reptiles. Squamata includes both the lizards and the snakes, because the two groups are closely related. One can think of snakes as a highly specialized group of lizards with no legs. There are also some reptiles with no legs that are consider lizards rather than snakes because of the greater similarity to most lizards.
Some authorities consider snakes and lizards distinct enough to each be a separate Order.
This group includes all turtles, from small pond turtles barely 10 cm long to mammoth sea turtles almost 2 m in length. Testudines is a comparatively small group of organisms with just over 250 species worldwide. Despite this they occur in most ecosystems, from deserts to oceans. Typical Snake One of the three Families of snakes that occur in Canada. The typical snakes, or Colubrids, contain the majority of snake species in the world, approximately 1500.
