Scientific Details

Meristics.
Dorsal fin spines/rays: VI-VIII; I, 8-9
Anal fin spines/rays: I, 7-9
Caudal fin rays: (segmented) 13 (no branched)
Pectoral fin rays: 17-21
Ventral fin spines/rays: I, 5
Lateral line: -
Gill rakers: 0-1 + 3-5 = 4-6

Interpreting fin count meristics.
Spines are in Roman numerals and soft rays are in Arabic numerals. Spines and rays that are continuous in one fin are separated by a comma. Fin sections are separated by semicolons.

Detailed descriptions of fin count and other meristics are in:

Genus level detail.
A genus of small well-camouflaged sand-dwelling gobies with many species in Port Phillip Bay, some of which are difficult to identify. They are distinguished on the basis of the number and kind of fin elements, the position and number of scales, head pore patterns, and other features such as colour pattern. And, males and females of the same species are sometimes very different in colour and fin shape.

Order level detail.
A large and highly diverse group of modern bony fishes many of which have a generalized perch like body form. Most have pelvic fins with one spine and 5 rays and the maxillary bone is excluded from the gape of the mouth. Interrelationships of the group are poorly understood and continue to be studied. They inhabit almost all aquatic habitats from high-altitude strams to the deep sea, although most are marine.

Family level detail.
Very large family representing almost 10% percent of all fish species. More than 230 genera and 1500 species are recognised worldwide, and there are more than 90 genera and 330 described species known from Australian waters.
