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 jaws, 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 is one of the largest groups of fish, with over 2,000 species worldwide. Cyprinids play important roles in their ecosystems, serving as both prey and predators. They are also popular in aquaculture and the aquarium trade due to their hardiness and adaptability.
