Humphrey the Whale
Humpback whale

Humphrey the Whale is a humpback whale that twice deviated from his Mexico to Alaska migration by entering San Francisco Bay. This behavior is unusual for a humpback whale, and Humphrey attracted wide media attention when he entered the bay in both 1985 and 1990. Both of his bay incursions resulted in rescue by the Marine Mammal Center, based in Marin County, California, assisted by the United States Coast Guard and hundreds of volunteers.
The last sighting of Humphrey was in the vicinity of the Farallon Islands in 1991.
Description
The humpback whale is a mammal which belongs to the baleen whale suborder. An adult usually ranges between 12–16 m (39–52 ft) long and weighs approximately 36,000 kilograms (79,000 pounds), or 36 tonnes (40 short tons). It is well known for its breaching, its unusually long front fins, and its complex whale song. The humpback whale lives in oceans and seas around the world.
Humpback whales have a stocky body with well-defined humps and black upper elements. The head and lower jaw are covered with knobs called tubercles, which are actually hair follicles and are characteristic of the species.
