Mexico has passed a landmark law to free approximately 350 captive dolphins from entertainment parks, marking a major victory for animal rights. In June 2025, the Mexican Senate unanimously approved legislation that bans dolphin performances, breeding in captivity, and swim-with-dolphin programs. According to the International Marine Mammal Project, the law mandates that all dolphinariums across the country shut down and relocate their dolphins to seaside sanctuaries within 18 months. This sweeping reform affects around 30 facilities and an estimated 350 dolphins currently held in tanks.

The move was endorsed by President Claudia Sheinbaum and reflects growing public support for animal welfare. According to The Animal Reader, Mexico has about 8 percent of the world’s captive dolphins, and the new law prohibits their use in shows, therapy sessions, and tourism activities unless tied to conservation or scientific research

The dolphins will be relocated to coastal sanctuaries designed to provide more natural environments while still allowing for veterinary care and monitoring. This historic legislation positions Mexico as a global leader in marine mammal protection and signals a shift away from commercial dolphin entertainment toward ethical conservation.
