On Antarctic safaris, remember to bring a microscope
Many people hope to come back from a wildlife safari with close-up pictures of lions or elephants – this picture below is my best attempt from a search for the largest land animals in Antarctica.
If you look hard you can see a reddish blob at the tip of the thumb — it’s Antarctica’s most aggressive land predator, an eight-legged mite known as Rhagidia.
Pete Convey, a biologist at the British Antarctic Survey (that’s his thumb), says that such tiny creatures evolved in Antarctica over tens of millions of years — they can freeze their bodies in winter in an extreme form of hibernation.
Penguins, seals and whales are the best known animals in Antarctica, but none live year-round on land, where the biggest creature is a flightless midge whose name is ”Belgica antarctica” and who’s about 0.5 cm long.
Magical Madagascar worth saving
Scientists have joined forces to save magical Madagascar by using a new method they hope to apply to other hot spots of biodiversity. For full details you can check my colleague Deborah Zabarenko’s story.
As someone who has had the great privilege of visiting this island continent twice I can only say: “Right on!”
