Why does this lizard have strange lumps on his back?

The strange lumps on the lizard's back could be due to a variety of reasons, including natural adaptations, health issues, or environmental factors. For some species, these lumps may serve as a defense mechanism, helping to confuse predators or mimic other organisms. Alternatively, they could be a sign of a parasitic infection, tumors, or other medical conditions. Observing the lizard's behavior and overall health can provide additional context for the presence of these lumps.
