Coral bleaching occurs when corals get too hot. Bleached corals are essentially sick corals and although they can recover, if temperatures are too warm for too long, the corals will die. Coral bleaching and in some cases death, is an impact of climate change.

Not only are the corals adorable, but they do a really good job explaining how running your air conditioning contributes to coral bleaching. Not cool enough for you? How about it comes with an awesome Aussie voice and nicknames like “Zooks”?
