Animal Species:Bony Bream, Nematalosa erebi (Günther, 1868)
The Bony Bream occurs in freshwater drainages in Australia and Papua New Guinea. It can tolerate a wide ranges of water temperatures and pH.

The Bony Bream is a relatively deep-bodied, compressed species with a blunt snout and bony toothless lower jaw. The scales along both the midline of the belly and the dorsal margin of the body in front of the dorsal fin, form a sharp serrate ridge. The last ray of the dorsal fin forms a long filament that may reach the base of the tail. The species is silvery to grey, sometimes with a greenish or reddish tinge dorsally.
The species grows to about 32 cm in length.
The species occurs in Australia and Papua New Guinea. In Australia it is known from freshwaters drainages across the north of the country and south through Queensland and inland New South Wales, Victoria and South Australia.

Distribution by collection data
The Bony Bream can tolerate a wide range of temperatures and pH, although is susceptible to low dissolved oxygen levels. It is often the first species to die when ephemeral waters begin to evaporate.
Feeding and Diet
The Bony Bream is schooling species that eats mainly algae and detritus.
Other behaviours and adaptations
According to Merrick & Schmida (1984) "Preliminary studies suggest that the bony bream has wide physiological tolerances, being able to survive salinities approaching those of seawater, temperatures between 9 and 38oC and pH values from 4.8 to 8.6. There are a number of reports of small individuals dying in large numbers after a succession of frosts - presumably due to lowered water temperatures."
