After a long-fought battle in Australia, a python bested a crocodile and swallowed the reptile whole over a span of several hours in Queensland, Australia.
The snake reportedly fought the croc for five hours in Lake Moondarra. Winning the fight, the python constricted its prey to death. The estimated 10-foot snake then dragged the 3-foot croc ashore and proceeded to swallow it whole in front of a group of onlookers.
National Geographic identified the snake as an olive python and the croc as a Johnson’s crocodile, both of which are native to Australia. After its hefty meal, the python should be full for at least a month.

epotus asked: Could you explain why Hydrogen Peroxide bubbles when applied to scrapes or cuts?
The majority of cells in your body contain catalase, an enzyme that catalyses the decomposition of hydrogen peroxide to oxygen gas and water in the following chemical reaction:
2 H2O2 → 2 H2O + O2
Therefore, if you pour hydrogen peroxide on a scrape or cut, the catalase leads to its decomposition; the bubbles that are visible will be bubbles of oxygen as it is produced by the reaction.
Your blood contains catalase, but the enzyme isn’t found on the surface of your skin, which is why pouring it onto skin without a cut doesn’t produce the same effect.
