A genus of small freshwater fish found in the Southern Hemisphere, particularly in Australia and New Zealand.
The scientific genus name Galaxias, derived from Greek 'galaxias' meaning 'milky,' referring to the small silvery dots on these tiny fish that resemble a milky appearance.
These aren't big impressive fish, but galaxias species are crucial indicators of stream health in Australia and New Zealand—scientists study them to understand whether ecosystems are thriving or degraded, making them tiny environmental heroes.
