More than 100,000 olive ridley sea turtles hauled themselves onto Playa Escobilla in Oaxaca to lay their eggs in one mass nesting event, Mexico News Daily reports.

Monitors from Mexico’s protected areas commission counted 101,500 females in this arribada, Spanish for arrival, the sixth of the 2026-27 season. It takes the season’s running total above 465,000 nesting turtles. During the event officials set aside a five-kilometre protected stretch of beach so the animals could nest undisturbed.

Escobilla is one of the most important olive ridley nesting beaches on Earth, and scenes like this are the result of more than three decades of protection. Scientists note that only a share of the eggs will hatch, and they are watching how hotter, drier conditions affect the nests, but the sheer number of turtles returning is a striking sign of what long-term conservation can achieve.
