Beaked Whales: Ziphiidae - Behavior And Reproduction

Not too much is known about beaked whale behavior or reproduction, because these animals live mainly in the open ocean and are hard to observe. They usually are seen in pods (groups) of ten or fewer animals, and within a pod they seem to swim or dive all at the same. This suggests that like other cetaceans, they have a good communication system. Some species regularly migrate, while others seem to stay within a home range.

From the scars that appear on the skin of some males, it appears that they fight each other with their tusks for the right to mate with females. One calf is born at a time. It stays with the mother and nurses for at least one year.
