Do amphibians and reptiles go through metamorphosis?

Do snakes have a backbone?

  • Do a lizard have a backbone?

Do amphibians have a backbone?

  • Is a gecko a reptile or an amphibian?

    Amphibian eggs must be kept wet, as most species develop after a larval stage, a phase during which they use gills to breath underwater. It isn't it until they reach adulthood that they form lungs. Since geckos are reptiles, the females generally lay, on land, two soft, white eggs that harden quickly.
  • Do lobsters have a backbone?

  • Are reptiles endothermic or exothermic?

    Animal Body Types - Further Reading. The two extremes in the animal kingdom are endothermic homeotherms and ectothermic poikilotherms. Most mammals, including humans, as well as most birds are endothermic homeotherms, while most fish, invertibrates, reptiles, and amphibians are ectothermic poikilotherms.
  • Do most reptiles have teeth?

    Snakes, lizards, crocodilians, and tuataras all have teeth. The teeth vary in their form, their attachment, and whether they are shed. Generally, the teeth of herbivorous species are broadly flattened with crushing surfaces. Those of most carnivorous reptiles are tapered to sharp points.
  • Do all reptiles have ears?

    Snakes have no visible ear, so they don't hear sounds as we do. But it's not quite right to say that snakes are deaf. They have vestiges of the apparatus for hearing inside their heads, and that setup is attached to their jaw bones, so they feel vibrations very well and may hear low-frequency airborne sounds.
