It assumes different forms (varieties/subspecies/species?) in different types of waters: most commonly it lives in turbid waters, as in claypans when it tends to be large and opalescent, but a darker, smaller form lives in clear vegetated water and another form in gnammas in the Murchinson area of WA, and still another form in some inland saline lakes in WA (Wolf 1911; Main 1953; Timms, in press; author, unpublished data).
