Elected representatives in government are in charge of the policy and funding that can make or break saving threatened species. Their decisions and actions matter.

Longman has or used to have 29 threatened animals within its boundaries. One of them is me, the Mary River Cod.

We took care to attach appropriate images that are as close to representative of each species as our resources and the availability of images allowed. However, we could not ensure perfect accuracy in every case. Some images show species that share the same genus but not at the species or subspecies level.

Maccullochella mariensis is found across 12 electorates.

The Mary River Cod is a yellowish to pale green fish, with a concave head profile and a protruding lower jaw. Mary River Cod have been measured at 23.5 kg, though it is uncommon to find individuals larger than 5 kg and 70 cm. Found in southeast Queensland in the Mary River system, their ideal habitat is described as deep, shaded, slow flowing pools with plenty of snags and log-piles. Mary River Cod form pairs and spawn annually around spring, the eggs are laid in nests in pipes and the males guard the brood until they disperse to search for food. The Mary River Cod is threatened by impoundment of streams, changes in flow regimes and removal of riparian vegetation.¹
