This image is linked to the previous image by the blue ice – but here I reveal more of it. The tiny upright figures of eight Gentoo penguins form what seems to be a welcoming committee. Actually, penguins gather in groups at water’s edge because it is too dangerous for them to swim out for food individually. For these penguins, there is safety in numbers; one will warn the others if a foraging seal interrupts their hunt. Antarctica is all about survival, for animals and man alike. This photograph offers us insights into one mechanism of survival.
