Neoceratodus forsteri

Overview

The Australian Museum describes large scales, small eyes and a continuous dorsal, tail and anal fin. The back and sides are olive to brown, sometimes blotched, with a pale underside. Natural populations inhabit the Burnett and Mary systems; introductions elsewhere should not expand that native range. Gills normally provide respiration, although the fish can surface for air.

Kemp’s study examined eggs and spawning habitat in Enoggera Reservoir and the Brisbane River. Eggs were usually attached to submerged vegetation or roots. Increasing daylight and suitable plants accompanied breeding, whereas measured rainfall, temperature, acidity and oxygen changes did not establish a consistent trigger. These observations concern the studied sites rather than every population.

Kemp also recorded daytime spawning evidence, qualifying earlier evening observations. The study did not confirm nest construction or care of offspring in this species. Its comparison with other lungfishes therefore cautions against transferring their reproductive behaviour to the Australian species.

Origins & earliest records

Kemp combined repeated field collections with laboratory assessment of egg development.

Evidence & interpretation

Direct observations constrain spawning habitat and timing while leaving some environmental relationships uncertain.
