In 2016, we gathered together these photos for Penguin Awareness Day, when people are encouraged to learn a little more about the different species of penguin and the threats they face.
Normally we'd be worried to see penguins around these parts, as they're native to the Southern Hemisphere, but we've done a little digging around and found London's exceptions to the rule.
NB. Penguin Awareness Day is different to World Penguin Day. We're not sure how it differs exactly, but it does.
