Life of Pi: Chapter 41 - 45

Along with Pi and the zebra, two more "guests" enter the lifeboat, a hyena and an orangutan named Orange Juice. As it begins to turn dark and become nighttime, Pi begins to worry as he is stuck on the ship with a hyena, an animal with deadly jaws that will eat almost anything. He eventually finds the hyena tearing at the zebra's leg. The concept of zoomorphism is brought up again with the orangutan and the hyena. Pi wonders if the two will get along as what kind of interaction between the two is unknown.
