Yes, reptiles have most of the same organs as you and I, and are vertebrates, they are not like worms.
no they do not
Yes they do. Cartilage is also found in your nose and ears!
No! They are made of cartilage.
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 they do
sharks dont have bones... their skeleton is made of cartilage
yes and the wiki answers are a lay don't believe in thi
reptiles do have backbones, everything excluding invertebrates have back bones.
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.
