A giant sea creature, possibly with tusks, washed up on a beach in Indonesia last week, freaking out people on the island of Seram and launching a global guessing game to determine what, exactly, it used to be. As images of the floating carcass rocketed around the internet, the scientific community asked itself: What is it? How did it get to an Indonesian island? And what does its presence say about climate change and whale migration habits? The people of Seram have a more pressing query: How do we get rid of it?
