All About Cyrpiniformes
No teeth? No stomach? No problem! All carp-like fish manage just fine because they have a special trick!
What are Cypriniformes?
Cypriniformes belong to a large order of fish that includes species like carp and barbs. Most of these species inhabit freshwater environments such as rivers, lakes, or ponds. A defining characteristic is that they lack true teeth in their mouths, instead possessing what are known as pharyngeal teeth in their throats. Their diet primarily consists of plants, although some also consume small animals or algae.
Main Characteristics of the Cypriniformes
1. They Have No Teeth
Cypriniformes feature what are called barbels around their mouths – small, soft extensions that act like feelers, helping them sense food in murky waters and pick it up from the bottom. However, they do not have teeth to chew their food. Instead, they use their pharyngeal teeth to crush their meals, functioning similarly to molars.
2. They Have No Stomach
Unlike most other fish, cypriniformes do not possess a stomach. Food moves directly from the esophagus into their long intestines, where it is digested very slowly. What’s the advantage of this? They are more agile because their bodies require less space for digestion. However, this means they need to eat quite regularly.
3. They Live in Freshwater
Nearly all cypriniformes thrive in freshwater. Only a few species can be found at river mouths, where saltwater and freshwater meet, creating what is known as brackish water – a mix of both types of water. This includes the European eel and the roach.

Amazing Facts About Cyrpiniformes
- There are 4,300 species of cypriniformes, a highly diverse group.
- The most well-known include carp, goldfish, zebra fish, white cloud mountain minnow, grass carp, and clown loach.
- Cypriniformes inhabit freshwater environments.
- They're different from many other fish because they only have one dorsal fin.
- Cypriniformes (along with perciformes) don't possess "normal" teeth. Instead, they have what are called pharyngeal teeth in their pharyngeal arches, which help them crush their food.
- The largest cypriniformes is the giant barb, which can grow up to 10 feet (3 meters) long and weigh as much as 660 pounds (300 kilograms).
- The smallest cypriniformes is Paedocypris progenetica, which is only 0.3 inches (7.9 mm) long.
