A new law has come into force in Mexico City that bans dolphinariums. It means that the dolphinarium based in the city, Dolphin Discovery Mundo Marino Six Flags, must now move the dolphins it holds or potentially face large fines.
The destination of any relocated dolphins must be approved by the authorities. Sadly, there are still many other locations in Mexico that hold dolphins in captivity, many offering swim-with opportunities to tourists.
