The Arowana is a freshwater fish found in Asia and South America. It's most commonly known for its jumping. It can leap as much as six feet above the water surface in search of insects and waterfowl. They've also been known to be both highly territorial and aggressive, so they will jump in defense. They're a type of fish called mouthbrooder, which means they carry their eggs, and their young for a short while, in their mouth to protect them - a truly unique creature even among its kind. Now you can have our handcrafted sterling silver box opener. This product is enough to rip through the toughest boxes. At the same time, for safety, we have blunted its edges. Even children can use it without getting hurt.
