 Key species of endangered whale
 
 Humpback whale
 One of the best known whales because of their distinctive flippers and tail flukes, their acrobatic 'breaching' and for the singing males on the breeding grounds.
 Once heavily exploited, the humpback is increasing in many parts of the world. There are probably now more than 30,000 in the southern hemisphere and 12,000-15,000 in the North Atlantic. Four whales per year can be taken by aboriginal whalers in St Vincent and the Grenadines.
