What is the niche of the humpback whale?

Humpback whales feed on fish, krill and plankton. Adult humpbacks have no natural enemies. Scars on juveniles suggest that they may be attacked by killer whales, but this has not been observed directly.

Humpback whales live in all the world's oceans. They make the longest migrations of any mammal species, traveling up to 16,000 miles per year between cold-water feeding grounds and the tropical waters where they mate and give birth. They are also known for the males' complex songs. They are popular subjects of whale watching tours because they are curious, approachable and engage in spectacular behaviors such as breaching.
