Question

digestive system of cyclostomata​

Answer 1

Answer:

Cyclostomata is a group of agnathans that comprises the living jawless fishes: the lampreys and hagfishes. The name Cyclostomata means "round mouths".

These fishes have only short gill rakers that help keep food particles from escaping out the mouth cavity into the gill chamber. ... Food is largely digested there and leaves the stomach in liquid form. Between the stomach and the intestine, ducts enter the digestive tube from the liver and pancreas.
