SeaWorld says that it has decided to end its contentious orca breeding program.
This means this will be the last generation of killer-whales at the park, which has 12 locations across the United States.
The whales will not be released into wild waters due to the chance of them dying after moving into a different habitat.
SeaWorld had been pondering the decision for quite some time before leading up to this decision.
The whales are the main showcase at three parks in California, Florida and Texas.
