The obtained koala genome sequence is much better quality than that for other sequenced marsupials opossum, tammar wallaby and Tasmanian devil and will really help us to assemble and compare genomes from all marsupials. It's because the leaves are so low in nutrients that koalas need more sleep than most animals which basically helps them conserve energy.
