Lungfish are freshwater fish which retain some primitive characteristics: such as the ability to breathe air and their lobed fins. They are found in Africa, South America and Australia. Of the six extant species, this Queensland Lungfish is the most primitive. His species has changed very little in over 100 million years. He is capable of surviving out of water for several days, but must be kept moist - other species can survive periods of total water depletion. He is long-lived species, with males reaching sexual maturity at 17 years, females at 22 years.
