The gentoo penguin is easily recognised by the wide, white stripe extending like a bonnet across the top of its head and its bright orange-red bill. It has pale whitish-pink, webbed feet and a fairly long tail – the most prominent tail of all penguin species. As the gentoo penguin waddles along on land, its tail sticks out behind, sweeping from side to side, hence the scientific name Pygoscelis, which means "rump-tailed" Gentoo penguin is very smug. And he is self-centered.
