Only after World War II did the secret spill: Ōkunoshima, located in the Inland Sea of Japan between Hiroshima and Shikoku, was the top-secret site for manufacturing chemical warfare. When the factories were closed down, a number of exotic wild rabbits were seen freely roaming the island. They were assumed to have been the test subjects for the chemical weapons, which the military failed to eradicate when the factory was demolished.

“The Rothschild Giraffe (Giraffa camelopardalis rothschildi) is among the most endangered giraffe subspecies with only a few hundred members in the wild. It is named after the famous family of the Tring Museum's founder, Lord Walter Rothschild, and is also known as the Baringo Giraffe, after the Lake Baringo area of Kenya, or as the Ugandan Giraffe. All of those that are living in the wild are in protected areas in Kenya and Uganda. (Recently it has been proposed that the Rothschild Giraffe is actually a separate species from other giraffes and not a giraffe subspecies).” – Wikipedia
