Ten protesters from People for the Ethical Treatment of Animals were removed from Seaworld's Aquatica San Diego Water Park.
Five people were arrested as they protested the captivity of orcas while dressed in wet suits designed to look like the massive mammals. The PETA-protesters were pretending to beach themselves under a sign with "SeaWorld kills" written on it.
Police removed the protesters by Chula Vista police for allegedly disturbing the experience of other park guests.
According to the Association of Zoos and Aquariums, a nonprofit group that accredits facilities like SeaWorld said that SeaWorld follows strict rules that have been implemented to protect orcas.
“SeaWorld is meeting, or exceeding, the highest standard of animal care and welfare of any zoological organization in the world,” the association said.
PETA says 39 orcas have died while in SeaWorld's custody.
The group is calling for a boycott of SeaWorld and its water park until the company agrees to retire the remaining orcas to sanctuaries in the sea.
