Chaque année, les baleines à bosse quittent leurs aires d'alimentation de l'océan Austral pour rejoindre les îles Australes, où elles viennent mettre bas et élever leurs petits dans les eaux abritées autour de Rurutu. Les observateurs peuvent ainsi y étudier leurs comportements naturels sans pratiquement les perturber.

The Australian sea lion (Neophoca cinerea) is the only pinniped endemic to Australia.
