Answer:
The captain tells Stefano that colomber is a fish rather a shark that all sailors fear above all. And that it will follow him until it has devoured him.
Step-by-step explanation:
"The Colomber," is a story by Dino Buzzatti in which a boy called Stefano Roi sees a strange fish on his father's boat. His father, who is a captain, tells him that the fish is a colomber, a type of shark that can only be seen by its future victim and close family. The father is afraid that the shark kills his son, so he sends Stefano away.
