The polar bears have been seen on the island and as a skeleton in the Sahara Desert. The bear in the desert had a Dharma Initiative collar on, signifying that this bear, was in fact, a product, or victim, of the DI. A Hanso Foundation Orientation video shows "Dr. Halliwax" holding a rabbit with a #15 and explaining to the viewers the Casimir Effect "field" to be studied at the Orchid Station. He is interrupted by a sudden event that produces an identical, #15 rabbit on the shelf behind him. He is dismayed by this and warns the room to keep the rabbits away from each other.
