Fred Jacobs, VP of communications for embattled Sea World Entertainment, has resigned after more than 20 years with the company.
The company did not give a reason for the departure but praised his work over 25 years.
Jacobs left the company briefly in the early 1990s for a stint at FleishmanHillard but has been its primary PR, media relations and communications lead for its theme parks.
Sea World has suffered revenue and visitor losses since a critical documentary, "Blackfish," was released in 2013.
The Orlando Sentinel first reported the exit.
