Yes, reptiles have most of the same organs as you and I, and are vertebrates, they are not like worms.
Yes they do. Cartilage is also found in your nose and ears!
No. Reptiles are vertebrates, and therefore have a spinal column made of bone.
No. Snakes are relatively recently evolved compared with other types of vertebrates and are the newest branch of reptiles. The first animals with backbones we fish, which were followed by amphibians and reptiles. Dinosaurs, mammals, birds, turtles, crocodiles, and lizards all had backbones and appeared before the first snakes slithered across the ground.
Yes, reptiles have backbones. They are vertebrates, meaning they have a spinal column made up of individual vertebrae that run along their backs, providing support and protection for their nervous system.
Yes they do
yes and the wiki answers are a lay don't believe in thi
sharks dont have bones... their skeleton is made of cartilage
No! They are made of cartilage.
Sharks are vertebrates (they belong to the phylum Cordata), so they have a spinal chord. However they are also cartilaginous fishes (they belong the the class Chondrichthyes) meaning that their skeleton is made of cartilage instead of bone. They do have a cartilage sheath that surrounds their spinal chord which could be considered a spine. There could be a semantic debate over whether that constitutes a spine, but I for one think it does.
They have backbones
Yes marine reptiles are vertebrates and have a backbone.
Vertebrates are animals that have a backbone and an internal bony skeleton and include fish such as barracudas.
