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]
