Crocodile wedding: A Mexican mayor marries a caiman every year, but the real story is about people and nature

• Every year, a small town in southern Mexico stages one of the world's most unusual wedding ceremonies.
• A mayor dresses for the occasion, a bride wears a white gown adorned with flowers, music fills the streets, and hundreds of residents gather to celebrate.
• The only difference is that the bride is not a person but a female caiman, a crocodile-like reptile native to Central and South America.
