Do reptiles have a jaw?

Homology: From jaws to ears. You (and all living mammals) have one bone in your jaw and three bones inside your ear. Lizards, on the other hand, have many bones in their jaw and one bone inside their ears.

Do snakes have a backbone?

In case you were wondering (cause they are soooo flexible), snakes actually do have bones. Animals with bones are know as vertebrates -- snakes are vertebrates. A snake's backbone is made up of many vertebrae attached to ribs. Humans have approximately 33 vertebrae and 24 ribs.
  • What do you call a snake's mouth?

    A snake's head contains the eyes, nostrils, mouth (and structures within), brain, and a special sensory structure called the vomeronasal or Jacobson's organ. Its paired openings are just in front of the snake's choana, the open slitlike structure on the upper inside of the reptile's mouth.
  • Do a lizard have a backbone?

    Reptiles are cold-blooded vertebrates. (Vertebrates have backbones.) They have dry skin covered with scales or bony plates and usually lay soft-shelled eggs. Check out mammals, birds, amphibians, fish, insects, and dinosaurs too!
  • Do cockroaches have a backbone?

    Insects are often described as “spineless” because they lack a backbone and internal skeleton. It is true that insects lack a backbone but they do have spines. In insects, spines are cellular outgrowths of the insect exoskeleton that are coated with cuticle. Cockroach spines are not at all wimpy.

Do amphibians have a backbone?

Amphibians are cold-blooded vertebrates (vertebrates have backbones) that don't have scales. They live part of their lives in water and part on land. Want to see other animals? Check out mammals, reptiles, birds, fish, insects, and dinosaurs too!
  • Is an amphibian?

    Amphibians are cold-blooded, which means that they are the same temperature as the air or water around them. There are more than 4,000 different kinds of amphibians. Members of this animal class are frogs, toads, salamanders, newts, and caecilians or blindworms.
  • Do lobsters have a backbone?

    Invertebrates are animals that do not have a backbone. Clams belong to a group of invertebrates called mollusks. The term shellfish includes members of the mollusk phylum and the crustacean subphylum. Crustaceans include lobsters, crabs and shrimp.
  • Is a toad an amphibian or reptile?

    Frogs and toads are both members of the same class — Amphibia — which means that they're both amphibians. Amphibians are cold-blooded vertebrates that spend the early part of their lives in water (breathing with gills) and the rest of their lives on land (breathing with lungs).

Do amphibians and reptiles go through metamorphosis?

Reptiles do not have a larval phase and do not go through metamorphosis. When the young are born or hatched, they look like miniature adults. Most reptiles lay shelled eggs on land. While most reptiles lay eggs, a few species of reptiles give live birth.
  • Do a bird have 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.
  • Do all reptiles have lungs?

    The skin of reptiles is dry and scaly, so they can live in arid locations (although many do not). However, they cannot use their skin as an organ of gas exchange. Reptiles depend entirely on their lungs for this. Their lungs are considerably more efficient than those of amphibians.
  • Do Ladybugs go through complete metamorphosis?

    This is a common kind of transition that many insects go through. In fact, ladybugs go through this same life cycle: complete metamorphosis. During complete metamorphosis, insects move through four distinct life stages: egg, larva, pupa, and adult.
