However, there are some animals that have very reduced or modified versions of these features:
* Snakes: While snakes have no limbs, they do have eyelids, but they are fused shut and covered by a transparent scale called a brille, giving the appearance of having no eyelids.
* Some Lizards: Some lizards, like the legless skinks, have lost their limbs, but they still retain eyelids.
* Earthworms: Earthworms have no legs or eyelids, but they have a segmented body and are considered invertebrates.
* Snails: Snails have no legs in the typical sense, but they do have a muscular foot and a shell. They lack eyelids, but have a thin membrane that protects their eyes.
It's important to remember that the animal kingdom is incredibly diverse, and there are many adaptations and variations in body structure.
