Yes, frogs are vertebrates and have a spine, or backbone. The skeleton of a frog is very similar to other vertebrates, such as humans, although some parts have changed to better fit the frog's lifestyle.Know More
Some vertebrae of the frog's spine have fused into a single bone called a urostyle, which is one key difference in the spine of a frog and that of other mammals. Frogs' spines also do not have a neck portion. Because of this change, frogs are unable to move their heads up, down or side-to-side. The pelvis has the ability to move along the spine, and the spine no longer connects to a rib cage, since frogs lack ribs.
