Labrus jaculator, commonly known as the Archerfish, is renowned for its unique hunting technique of shooting jets of water to dislodge insects from overhanging vegetation. It thrives in brackish and freshwater environments in Southeast Asia and Australia, displaying a silver body with dark bands and a distinctive pointed snout.

Labrus jaculator, commonly known as the Archerfish, is native to the Indo-West Pacific region. It is primarily found in countries including India, Sri Lanka, the Philippines, Indonesia, Papua New Guinea, and northern Australia.

The Archerfish typically inhabits brackish waters of mangroves, estuaries, and coastal areas. It is well adapted to environments where fresh and saltwater mix, often thriving in tidal zones and sheltered coastal waters. The climate in these regions is typically tropical to subtropical, providing warm, nutrient-rich waters that support diverse aquatic life.

In its ecological niche, the Archerfish is known for its unique feeding behavior, where it preys on insects and small crustaceans by shooting jets of water to knock them into the water. This adaptation allows it to exploit food resources that many other fish cannot reach. The Archerfish's ability to navigate and thrive in both brackish and freshwaters enables it to adapt to various ecological conditions within its range.
