The eyesight of the Australian Lungfish has been reported to be poor and the location of prey was thought to be based on the sense of smell rather than sight.
Australian lungfish (Neoceratodous forsteri: Dipnoi) have low genetic variation at allozyme and mitochondrial DNA loci: a conservation alert? The Australian lungfish has a fully functioning lung as well as gills, although the lung is mostly used only when the fish is very active, or when the water becomes muddy or low in oxygen. Other articles where Australian lungfish is discussed: lungfish: Size range and distribution: The Australian lungfish, Neoceratodus forsteri, may weigh up to 10 kg (about 22 pounds) and grow to a length of 1.25 metres (about 4 feet). Australia is a signatory to CITES and has strict regulations on the export of the Queensland Lungfish. Spawnings of lungfish generally produce surviving juveniles only when conditions for both egg-laying and the growth of eggs and young are ideal, perhaps on average every 5 or so years. Molecular Biology and Evolution 21(8): 1512-1524.
The sound made when the Lungfish empties and refills its lung reportedly sounds like the "blast from a small bellows".

Image credit: gadigal yilimung (shield) made by Uncle Charles Chicka Madden. Arthington, A.H. 2009. Due to high costs and legal requirement involved in breeding these fish, lungfish are not cheap to purchase, so they are really only suitable for the committed enthusiast. Second Edition. Maximum reported length 180 cm, although most are smaller. The dorsal fin commences in the middle of the back and is confluent with the caudal and anal fins. The Australian Museum respects and acknowledges the Gadigal people of the Eora Nation as the First Peoples and Traditional Custodians of the land and waterways on which the Museum stands. Mostly carnivorous, consuming frogs, tadpoles, small fish, moluscs, freshwater shrimp and earthworms, however, it has been observed to eat some aquatic and terrestrial plant material. Journal of Experimental Zoology Part B, Molecular and Developmental Evolution 304: 229-237. Close following occurs for some time before spawning, with the movement of one fish influencing the movement of the other. (ed.) Ten rows occur on each side, grading to small scales on the fins. & Bray, D.J. 303 figs. It occurs naturally in the Burnett and Mary River systems although has been introduced into other rivers and reservoirs in south-eastern Queensland.

We pay respect to Elders – past, present and emerging – and acknowledge the important role Aboriginal Peoples and Torres Strait Islanders continue to play within the Queensland Museum Community. A guide to stocked waters. The Australian Museum will reopen to the public on Saturday 28 November after a 15 month $57.5m building transformation, and general admission will be FREE to celebrate the reopening of this iconic cultural institution. Reproductive Physiology of Fish, Austin Texas. It can grow to ~1.5 m in length and weigh ~40 kg, enjoying a diverse diet of plants, frogs, small fish and invertebrates. The species was described in 1870 by Australian Museum staff member Gerard Krefft. Queensland Lungfish. It has five pairs of gills and flipper shaped fins.

Food items include mainly frogs, tadpoles, small fishes, snails, shrimp and earthworms. Report on preservation of Ceratodus. & Molnar, R.E. & Johanson, Z. Bookings are essential to visit Cobb+Co Museum. Spawning involves pairs of fish and usually occurs at night between August and December with the peak of activity around late October.
2002. The larvae slowly absorb the yolk sac and begin to feed after 41 to 56 days from hatching. Brooks, S., Espinoza, T., Kennard, M., Arthington, A.
1994. The Australian Lungfish has a long, heavy body with large scales. Growth is very slow, with young reaching 6 cm in length after 8 months and 12 cm after two years. Copeia 1993(1): 240-242. Johann Ludwig Gerard (Louis) Krefft, 1830–1881 was one of the few Australian scientists to accept and propagate Charles Darwin’s theory of evolution. Total length is up to 150 cm, but most commonly found at about 90 cm.
Kemp, A. 1: 181-198. Molecular evidence that the lungs and the swimbladder are homologous organs. Age structure of the Australian lungfish (Neoceratodus forsteri). Fossils of lungfish almost identical to this species have been uncovered in northern New South Wales, indicating that Neoceratodus has remained virtually unchanged for well over 100 million years, making it a living fossil and one of the oldest living vertebrate genera on the planet. The Australian Lungfish is a long, heavy-bodied freshwater fish that looks a bit like a fat eel. BMC Ecology 8: 21. It can survive out of water in drying river beds, billabongs or gullies for extended periods, as long as it is kept moist in the bottom mud or aquatic weeds. Zool. Formerly widespread, at one time at least seven species of lungfish were in Australia. At the onset of the dry season when water bodies dry up, this species is able to secrete large quantities of mucous. Merrick, J.R. & Schmida, G.E. 1981. This explains why juveniles have always been difficult to find and why adults are much more commonly seen.
Lungfishes belong to an ancient lineage of air-breathing fishes that first appeared in the fossil record about 380 million years ago and were common during the Devonian Period. Developmental plasticity and disparity in early dipnoan (lungfish) dentitions.
Ecology and demography of the Queensland lungfish (Neoceratodus forsteri) in the Burnett River, Queensland with reference to the impacts of Walla Weir and future water infrastructure development. Its home range rarely extends beyond a single pool or, occasionally, two adjacent pools. Fully mature when he arrived from Sydney for the Chicago World’s Fair of 1933, he is at least 80 years old—and possibly much older. The remarkable lungfish otolith.

The Australian lungfish reportedly breathes air through the nasal openings, the mouth remaining closed. They have stout, elongated bodies and flattened heads with small eyes. Fossils identical to N. forsteri found in northern New South Wales have been dated at 100 Million years, during the early Cretaceous Period, making this species a member of the oldest extant vertebrate genus. Head wide, flat; body stout, elongated; skeleton is partly ossified and partly cartilaginous; mouth small and subterminal; massive tooth-plates having surfaces adorned with radiating ridges, toothplates resting on the palate and inside the lower jaw; eyes small; numerous sense pores; lungs used to breath air and gills to respire in water; internal nostrils, two small openings inside the labial cavity, and a pair of posterior openings in the roof of the mouth; a single well-developed lung with alveolae and blood circulation somewhat similar to that in higher vertebrates. — Conservation Genetics 19: 587–597, https://doi.org/10.1007/s10592-017-1034-7.

Along with several African and South American lungfishes and the Coelacanth – another lobe-finned fish later discovered in the Indian Ocean – they are often purported to be surviving links in the evolutionary chain between fishes and amphibians. Bruton, M.N. https://doi.org/10.1371/journal.pone.0210168. 409. The recent work of Watt et al (1999) has shown that the Australian Lungfish can use electroreception to locate hidden prey. Kemp, A.
