Authentic crocodile leather features distinctive umbilical scars and small sensory pores (integumentary sensory organs) near the scales' edges, which are absent in embossed cowhide. Buyers should check for natural scale patterns that are slightly asymmetrical and ensure the leather has been processed using high-grade tanning agents to prevent cracking. For premium applications, prioritize 'Belly Cut' leather for its softness and uniform scale structure, or 'Back Horn' leather for a rugged, 3D texture.
