Vertebrates – animals with a backbone. Sponges, corals, worms, insects, spiders and crabs are all sub-groups of the invertebrate group – they do not have a backbone. Fish, reptiles, birds, amphibians and mammals are different sub-groups of vertebrates – they all have internal skeletons and backbones.
What makes vertebrates unique?
Vertebrates are differentiated by having a vertebral column. As chordates, all vertebrates have a similar anatomy and morphology with the same qualifying characteristics: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail.
Do lizards have lungs?
All reptiles breathe through their lungs. Lizards do not have a diaphragm; instead, their chest muscles move the chest wall, which inflates and deflates the lungs. A few lizard species use their throat muscles to “gulp” air in a process called buccal pumping (a process also used by amphibians).
Do lizards have a placenta?
Within the lizards are oviparous species, viviparous species that have a very simple placenta and little nutrient uptake from the mother during pregnancy (lecithotrophic viviparity), through a range of species that have intermediate placental complexities and placental nutrient provision, to species that lay …
What do lizards do at night?

How does a legless lizard move on its own?
Their legs are not positioned like a mammals, they stick out on each side and push the body along, undulating or wriggling.
