Niloticus Crocodile, a group of crocodiles living in the Nile River Basin, has more square scales than round scales. The square texture is neat, and it has the best abdominal dyeing effect than other crocodile skins. Alligator Crocodile is the most famous alligator in Mississippi. Alligator leather is usually used in small ornaments such as alligator leather straps and bracelets.
