Dead Marine Animals Showing Up Along Gulf Coast

But so far, it looks like the oil spill is not to blame. But why did 60 dead endangered turtles wash up over three weeks? And what about the dead dolphin? Seems odd, although officials with the Mississippi Department of Environmental Quality said that fish they've tested have not been killed by oil, but a lack of oxygen in the water. They also say low oxygen levels are common this time of year due to changes in temperature.

Still, though, 60 sea turtles over 3 weeks? Seems like an awful lot...
