Scomberesocidae

Scomberesocidae is a small family of marine fish commonly known as sauries. These fish are characterized by their slender, elongated bodies, small fins, and a distinctive beak-like jaw formed by the extension of both the upper and lower jaws. Sauries are pelagic, meaning they live in the open ocean, and are found in temperate and tropical waters worldwide. They are surface feeders, preying on small crustaceans, plankton, and other small fish. Their speed and schooling behavior are important adaptations for avoiding predators and finding food.

The family Scomberesocidae currently contains only one genus, Scomberesox, with two recognized species. These species are Scomberesox saurus, the Atlantic saury, and Scomberesox scombroides, the Pacific saury. While closely related to the billfishes like marlins and swordfish, sauries are significantly smaller and lack the large, prominent bill. Their economic importance is generally low, though they are sometimes caught for bait or as a food source in some regions. Their biology and ecological role in marine ecosystems are subjects of ongoing scientific study.
