They did and still do have bones.
Yes, Amphibians are Vertebrates which are animals with backbones.
Yes, all amphibians have bones.
yes
because their limbs and bones are stronger than those of amphibians
Endoskeleton - they are vertebrates and their bones are inside!
No. Amphibians have bones, including a backbone, as they are vertebrates.
Amphibians do not have true bones like those found in mammals; instead, their skeletal structure consists of a combination of cartilage and bone. They do have bones that contain calcium, which provides structure and support, but these bones are generally less dense compared to those of reptiles or mammals. The presence of calcium in amphibians is important for various physiological functions, including muscle contraction and nerve function. Overall, while amphibians possess calcium-containing bones, their skeletal system is more flexible and adapted to their unique life cycle and environment.
because it has bones
Fish, reptiles, amphibians, birds, and mammals are all vertebrates. They all have a backbone and internal bones.
I don't believe that amphibians such as frogs and toads have a skeleton at all - just connective tissue - no bones! _________________________________________________________________________________________ um i don't believe that is correct. amphibians are vertebrates meaning they hav a backbone
Birds have hollow bones to help them fly. Solid bones would add to much weight and make it impossible to fly.
I think as they are tadpole they are slowly forming a spine
