One of the artists whose work is on show at the Sydney Biennale is Maria Fernanda Cardoso. Her amazing work looks at the microscopic world of insect penises. It's called The Museum of Copulatory Organs and it reveals that when it comes to insect penises, it's not size that matters, but shape. The reproductive organs of insects come in all different shapes and are actually quite beautiful. Some look like intricate flowers, others like exotic coral. Most look as though they belong to the biology of some distant planet. Maria Fernanda Cardoso has made her fascination with the natural sciences the basis of her art for many years, with the help of her husband and artistic collaborator Ross Harley.
