In January 2024, a scientific team installed a satellite transmitter on a fin whale in Chañaral de Aceituno, northern Chile. [^1]

The fin whale traveled over 3,000 km in 18 days, crossing Cape Horn to reach the Namuncurá-Banco Burdwood Marine Protected Area in the South Atlantic. [^2]

This record constitutes the first documented interoceanic round trip for the fin whale species in South America. [^3]

Sperm whales have returned to the coastal waters of Chañaral de Aceituno, Chile, for the fourth consecutive year since 2025. [^4]

The whale remained in the South Atlantic for a month and a half feeding before returning to the same point on the Chilean coast. [^5]

In March 2026, a team of researchers successfully satellite-tagged two sperm whales to track their movements and feeding zones. [^6]

Researchers have identified more than 20 distinct sperm whale individuals in the Reserva Marina Isla Chañaral using unique tail fluke patterns. [^7]

The recurring whale sightings have transformed the previously isolated fishing village of Chañaral de Aceituno into a tourist destination, with hundreds of visitors arriving between September and summer. [^8]
