The Javan mongoose is a small predator with a long body and short legs. It runs fast, climbs well, and is known for its ability to hunt snakes.
The Javan mongoose is smaller than most other mongooses and very agile. It helps control rodent and snake populations, but in areas where it has been introduced, it can harm local birds and lizards.
