GULF OF MEXICO - Scientists have spotted a dead sperm whale in the Gulf of Mexico, and are doing tests to see if the oil spill had anything to do with its death.
The whale was found floating 77 miles due south of the Deepwater Horizon spill site.
It is the first dead whale spotted since BP's rig exploded on April 20.
The whale was not found in oiled waters, but scientists can't yet say where or how it died.
They say its condition suggests it has been dead for several days to more than a week, and they are taking samples from it to glean information on how and where it died.
They live at depth in areas where subsurface dispersants and oil are present, and feed on deepwater squid, which may also be impacted by the oil and dispersants.
The sperm whales are an endangered species, and some scientists say that just a few sperm whale deaths could endanger the long-term survival of the Gulf's entire native sperm whale population.
