The drummer for rock band Motley Crue offered in his letter to bring a camera team from People for the Ethical Treatment of Animals to the Orlando park to settle the disagreement by filming the artificial insemination process, the New York Daily News reported Friday.
Lee wrote in his original letter last week that Tilikum the orca whale was being kept in captivity to serve as "chief sperm bank."
"We know from SeaWorld's own director of safety (as well as videos on the Web) that the way you get his sperm is by having someone get into the pool and masturbate him with a cow's vagina filled with hot water," Lee stated in a letter to the park.
SeaWorld officials said the claims in Lee's letter were "beyond ludicrous."
"The process of collecting semen for (artificial insemination) doesn't differ in any meaningful way from the techniques employed in managing livestock or other species for zoological display," the SeaWorld representative said.
