Fossil evidence suggests that this species of Australian lungfish has remained relatively unchanged for some 100 million years. As their common name suggests, these fish have both lungs and gills, which allows them to obtain oxygen from water and air. Lungfish are extremely long lived—the oldest known specimen resides in Chicago and is more than 80 years old.
All six living lungfish species lay eggs; the Australian lungfish differs from its relatives in that it does not exhibit parental care.
