Residents and government biologists inspect the corpse of a 12-tonne minke whale that was found dead on a beach of the Arapiuns River at Sao Jose do Arapixuna, near Santarem in the heart of Brazil's Amazon region , November 20, 2007. The 18-foot (5.5-metre) whale was found dead after swimming aimlessly along numerous tributaries, and was first seen last week on the Tapajos River, a tributary of the Amazon, after swimming some 1,000 kms (1,600 km) from the Atlantic Ocean, its normal habitat.
