The Southern Shortfin Eel typically inhabits cooler freshwater areas in Australia, New Zealand, and Tasmania. This species is dark brown and olive green, with a lighter underbelly and a shorter dorsal fin. Due to their snake-like locomotion, they can briefly go on land.

The Southern Shortfin Eel also starts life in the deep Coral Sea, turning from larvae into transparent glass eels. Braving numerous challenges, these eels journey from their birthplace to freshwater habitats. Female eels are larger than males, growing up to 3.3 feet long.

These types of eels prefer to stay hidden during the day under rocks and vegetation. They are active at night, feeding on fish, crustaceans, insects, and worms.
