These are small American alligator heads from 3 foot gators with added clear and opaque glass eyes. These heads are approximately 4-7/8 inches to 6 inches. Alligators have between 74 and 80 teeth in their mouth at a time. As teeth wear down they are replaced. An alligator can go through 2,000 to 3,000 teeth in a lifetime, and they are sharp! These are a great gift for reptile collectors, teachers, students, and collectors of unusual items. A taxidermy process cures the alligator skin and the alligator skull so it will be preserved for years.
