Golden Perch

The golden perch, Macquaria ambigua, is an Australian native freshwater fish, primarily of the Murray-Darling river system.
The genus name for golden perch — Macquaria — derives from the Macquarie River where the first species in the genus was collected. The specific name for golden perch — ambigua — may derive from Latin form of the word 'ambiguous', which has connations of "two or more sides", and thus refer to the strong lateral compression (narrow, deep, flanks) adult golden perch display, but more likely refers to the confusion over where the original specimen ('holotype') was collected.
