A large Burmese python in the US state of Florida ate a whole alligator for dinner. How do we know this? Because scientists found it inside the snake's stomach!
The 5.4-metre python was caught by workers in the Everglades National Park, says scientist Rosie Moore.
Later, in a laboratory, scientists found the 1.5-metre alligator in its stomach.
A video of the discovery shows scientists wearing gloves and looking at the bulge in the python's stomach before cutting it open on the floor. The scientists are then seen sliding the alligator out of the snake's stomach.
The size of the alligator and the strong stomach juices made for a very unpleasant scent.
"The smell was horrendous," she says.
Burmese pythons are called an "invasive species" in Florida. This means they do not come from that place, but they have invaded it, and this is causing problems for other wildlife.
Burmese pythons come from Asia. They are one of the largest snakes in the world and can reach lengths of more than six metres.
Last month, more than 230 pythons were caught in the Everglades. It was part of a competition to remove the invasive species from the national park.
"These snakes have successfully invaded areas such as Everglades National Park," says Rosie. "This is a threat to a variety of wildlife, because the pythons eat so many other animals."
