(CNN) — California is now the first state to ban breeding and holding killer whales in captivity. Governor Jerry Brown signed the bill Tuesday.
Under the new law, the killer whales already in captivity may remain in the state, but they can only be used for “educational presentations.”
SeaWorld — which operates a park in San Diego — had already announced similar changes; the end to its breeding program and the phase out of killer whale theatrical shows.

According to its website, SeaWorld San Diego plans to retain the 11 whales under its care.
