Jiménez told officers he’s not going to stop swimming with whales and dolphins, "because it’s magical and others do much worse things."
The agency cited him for prohibited activity in regard to endangered whale species and harassing wildlife in a state park.
Jiménez is due to appear in court on the morning of May 11.
