Dual: Eow! Goliath vs. Goliath ?

Take a look at this picture. It's gross as hell, but still amazing in its own funny way: It's a giant cobra snake (Florida) that apparently tried to eat an alligator....and eventually exploded ? According to one source, biologists assume that the alligator was able to "bite itself" out of the cobra. Another source said however that both creatures died.
