Animal Species:Common Galaxias, Galaxias maculatus (Jenyns, 1842)
The Common Galaxias is usually found in still or slow-flowing waters like streams rivers and lakes. They feed on aquatic and terrestial insects and crustaceans.
Standard Common Name
Common Jollytail, Eel Gudgeon, Jollytail, Lananga, Minnow, Native Trout, Pulangi, Slippery Tarki, Spotted Minnow, Whitebait
The Common Galaxias can be recognised by a combination of characters that include an elongate body, dorsal and anal fins located opposite each other at the posterior of the body and a forked tail. Its colouration ranges from green to amber, with a variable covering of spots and blotches.
The species grows to 19 cm but is more common to about 10 cm in length.
The Common Galaxias is very widespread. It is found in Australia, New Zealand, Patagonian South America and the Falkland Islands.
In Australia it is known from coastal streams in southern Queensland, New South Wales, Victoria, Tasmania, eastern South Australia, and from parts of southern Western Australia.

Distribution by collection data
Adults live in low-elevation streams.
Feeding and Diet
They feed on aquatic and terrestial insects and crustaceans.
They migrate downstream to spawn during new or full moons, mostly in Autumn. Thousands of small eggs are laid in vegetation on the margins of estuaries at spring tides, and often spend up to two weeks out of water until the next spring tide. The larvae leave the estuary and spend 5 to 6 months at sea as juveniles before returning to freshwater.
