The chief executive of SeaWorld, Jim Atchison, has resigned as a result of a huge backlash following the 2013 film Blackfish.
The film criticised the way killer whales were treated at the aquatic theme park, and visitor numbers have dropped significantly since.
In August, SeaWorld acknowledged that the film had hurt its profits.
SeaWorld's share price has fallen a massive 44% this year, and now trade at just $16 a share.
In a statement, SeaWorld said its downfall was due to "a combination of factors including negative media attention in California along with a challenging competitive environment."
Current board chairman David F D'Alessandro will take over as interim chief executive until a replacement can be found. The board also confirmed that it will go ahead with restructuring plans in a bid to save around $50m.
