All these species are facing man-made threats - from melting sea ice and habitat loss to poaching and overfishing of their food - and need help to survive. Some penguin species are a hair’s breadth from extinction; others have a little more time.
But one thing is crystal-clear, according to the team at the Two Oceans Aquarium: it’s time for everyone to turn their love of penguins into action.
The South African coast is home to one of these endangered species: the African penguin.
Together with members of the equally endangered northern rockhopper penguin species, the Two Oceans Aquarium aims to spread awareness about the plight of the birds during Penguin Week, which runs until Sunday.
