Here comes a simple but elegant reptile tattoo of a lizard. Isn’t it nice? The tattoo design is used at the elbow and also near the neck. This black tattoo gives the outline of a reptile; it can be lizard or crocodile or any of the sister species. Reptiles are air-breathing, cold-blooded vertebrates that have skin covered in scales as opposed to hair or feathers. They are tetra pods (having or having descended from vertebrates with four limbs) and amniotes, whose embryos are surrounded by an amniotic membrane.
