Tañon Strait lies between the islands of Negros and Cebu in the Philippines. The strait connects the Visayan Sea to the Bohol Sea.
The Tañon Strait is known for whale and dolphin watching, with tour boats operating from a wharf in Bais City.
On February 7, 2008 the Supreme Court of the Philippines ordered the Department of Environment and Natural Resources and the Department of Energy to comment on a certiorari petition filed for toothed whales, dolphins, porpoises and other cetacean species in the Tañon Strait to stop oil exploration by Japan Petroleum Exploration Co. Ltd. (JAPEX) in the protected waterway. The strait serves as a marine wildlife reserve that provides grounds for breeding, feeding and resting to 11 species of marine mammals. The court was asked to recognize the petitioners as "Filipino mammals" with constitutional rights.[1]
