How Humpbacks Travel
Whales are known for traveling in packs, and migrating to the South Pacific Ocean for breeding purposes, and for its warm temperature. They are known to travel in packs for the purpose of protecting their offspring, which is why Hauser was not shocked to have seen two, or possibly three whales in the same area.
Protective laws have been spread due to the near extinction of the humpback whale, with the species actually rising in numbers since these laws have been passed.
