The Ruvettus species are a group of fish belonging to the family Gempylidae, commonly known as snake mackerels. These fish are characterized by their elongated bodies and smooth, shiny scales. They are typically found in deep ocean waters and are known for their predatory behavior, feeding on smaller fish and squid. Ruvettus species are notable for their high oil content, which can make them unsuitable for direct human consumption due to potential digestive issues. However, they are often used in the fishing industry for bait or processed into fish meal. Their unique adaptations allow them to thrive in deep-sea environments.
