The Blue-spot Goby of eastern Australia is a new species that has been called Pseudogobius olorum (Sauvage, 1880) in the literature for many years.
This species has a rounded snout, eyes positioned high on the head and pelvic fins fused into a cup-shaped disc.
It is grey-brown above with scattered darker blotches, and white or cream below. The common name of this species comes from the blue spot on the first dorsal fin.
The Blue-spot Goby is a carnivorous species that grows to 76mm in length.
It is often found in muddy areas and seagrass beds in the upper reaches of estuaries. It is also known to penetrate upstream into freshwater and may remain there for extended periods of time.
