What is a humpback whale?

Humpback whales are named for the distinctive hump on their backs. The species lives in all oceans around the world and has one of the longest migrations of any mammal on the planet, according to the National Oceanic and Atmospheric Administration Fisheries.

They can grow up to about 60 feet long and weigh up to 40 tons, and can live around 80-90 years. Humpback whales feed on krill and small fish, and strain huge volumes of water through the baleen plates in their mouths, which act as a filter-feeding system.

Their population has been severely reduced from historical numbers thanks to commercial whaling. Under the Endangered Species Conservation Act in 1970 and then under the Endangered Species Act in 1973, the U.S. had listed all humpback whales as endangered.

As of 2024, four of the 14 distinct population segments are still protected as endangered and one is listed as threatened, according to NOAA Fisheries. In U.S. waters, three humpback whale stocks are designated as depleted under the Marine Mammal Protection Act.
