Species: Neoceratodus forsteri (J.L.G. Krefft, 1870) - Queensland lungfish

Of all extant (living) fishes, humans are most closely related to the Queensland lungfish (citation needed). By examining fossil records of specimens 380 million years old, it is evident that today's Australian lungfish has remained relatively unchanged. The Queensland lungfish has a single dorsal lung, and out of all extant lungfishes, is the only facultative air breather (it has the choice to breath air or use gills). During periods of drought and stagnate water, this species is capable of surfacing to gulp air every 1-2 hours; however, only the S. American and African species of lungfishes are capable of aestivating, or surviving outside of water for long periods (Allen, 2002).

Tips for Identifying: First the BAM then the FAD.

Weighs up to 40.0 kg ( ~88 lb) (Allen, 1989)
Length up to 170 cm ( ~5.58 ft) (Kemp, 1995) Normally 100 cm (3.28 ft) (Allen, 1989)
Countershading with darker brown on backside and lighter whitish coloration on ventral side.
Wide mouth, slightly subterminal.
Lobed, fleshy fins that can be used for walking as well as steering during locomotion in water. Has a strong leptocercal (modified diphycercal) tail.
Area (Habitat):
Freshwater. Endemic to the Mary and Burnett river systems in south-eastern Queensland (Whitley, 1980). Prefers a muddy, gravelly, or sandy benthic substrate (Allen, 2002).
Fairly mellow, sluggish predators.
