Boa Constrictor Nabs Monkey
A boa constrictor eats an adult female Purús red howler monkey in the Brazilian Amazon. Usually the snakes have been known to eat smaller animals.
Bat-eating spiders are common and apparently creep around every continent, except Antarctica, devouring various bat species. Here, a dead bat (Rhinolophus cornutus orii) caught in the web of a female Nephila pilipes on Amami-Oshima Island, Japan.
Anaconda Devours Giant Rodent
Now this here's a match of the biggest and baddest: A green anaconda, which can grow up to 20 feet (6 meters) in length and a scale-tipping 200 pounds (90 kilograms) in weight, takes on the world's largest rodent — the capybara. This furry creature (inset) can weigh up to 100 lbs. (45 kg). Good thing the anaconda's lower jaw isn't fused to its skull, allowing the beast to open its mouth wide enough to capture the giant rodent and squeeze it to death. Every time the capybara exhales, the anaconda squeezes tighter, according to the National Geographic video.
Bug Eats Fish
Scientists captured the larva of a giant water bug feeding on a small fish. The insects inject caustic digestive saliva into their prey, liquefying their meal from the inside so that they can suck out the contents.
Gator vs. Python
An American alligator fights with an invasive python in Everglades National Park. The gator appears to be winning, but pythons sometimes come out ahead in these struggles and have even eating alligators.

Shark on Shark

Don't Mess with Otters
In 2011, a photographer captured an otter's attack on an alligator in Florida.
Snake vs. Centipede
This unlucky viper messed with the wrong centipede. Scientists think it's possible the centipede tried gnawing its way out of the snake after it was swallowed.
