Lombok, Indonesia Sentinel — Thousands of people flocked to the shores to participate in the Bau Nyale traditions, a centuries-old ritual of catching sea worms. Equipped with nets, flashlights, and containers, people descended on the beaches of Central Lombok, West Nusa Tenggara (NTB) on Sunday (February 16), as early as 4:00 a.m. to join the festivities.
Bau Nyale, which translates to “catching Nyale,” is an annual tradition observed by the people of Lombok. Nyale refers to a type of marine worm that emerges only once a year at select locations along the southern coast of Lombok Island.

The event is deeply rooted in the Sasak calendar, occurring on the 20th day of the 10th month. This event is also coinciding with the rise of the “Rowot” star, which is linked to the agricultural cycle. Locals believe these sea worms bring prosperity to those who respect them and misfortune to those who do not.
