Cyprinids are a family of freshwater fish known as Cyprinidae, which includes species like carp, goldfish, and minnows. They are characterized by their lack of teeth in the jaw, instead having pharyngeal teeth that help them grind food. Cyprinids are found in various habitats, including rivers, lakes, and ponds, and are known for their diverse sizes and colors. This family of fish is important in both ecological and economic contexts. Many cyprinids serve as a food source for larger predators, while others are popular in the aquarium trade. Additionally, some species, like common carp, are cultivated for food in aquaculture systems.
