This is a somewhat infamous chapter of Moby Dick--a rather lengthy digression in which the author gives a brief lesson on cetology, listing the various types of whales that were known about in the 19th century. The author admits that his biological lesson will be incomplete "because any human thing supposed to be complete, must for that very reason infallably be faulty." Nevertheless, Melville says, "I will try." Here are the types of whales he describes. You may click on the whale's name to read more about each animal.
