Its head is covered by a grotesque, tumor-like growth that looks disturbingly unnatural. While completely real, its appearance has left many viewers Late at night, by the shore in Australia, something massive washed up. At first, it looked like nothing more than a lump of rock or driftwood. But as the camera moved closer, a huge carcass came into view, its body pale, swollen, and strangely coiled.

Number 9. In Northern Australia, the Daintree River is already home to crocodiles. But this footage shows something different. At first, the water looks calm, disturbed only by the current.
