Several new species of peacock spider – just a few millimetres long and featuring extraordinary colours – have been discovered in Western Australia and South Australia. Jürgen Otto, a biologist from Sydney, has been researching the arachnids since 2005, and has gained a significant following online with his footage. He believes there are now 48 confirmed species of peacock spider within the Maratus genus, found across Australia but particularly in Western Australia – and many more awaiting confirmation. Here: Maratus Tasmanicus, one of seven new species of peacock spiders studied by the Sydney biologist Jürgen Otto. (Photo by Jürgen Otto)
