Four salient features of cyclostomes are:
1. They have a roundish, elongated body. The body of cyclostomes resembles that of an eel.
2. Unlike fishes, they have no jaws present in their buccal cavity. Hence, they are known as agnatha.
3. Unlike fishes, they do not have any scales on their body even though they are aquatic organisms.
4. They have no exoskeleton in their bodies. The endoskeleton is devoid of any bone. It is entirely made of cartilages.
