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.
Wannon has or used to have 39 threatened animals within its boundaries. One of them is me, the Glenelg Freshwater Mussel.
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.

The shell is strong and almond-shaped, with a rounded posterior border, and both the umbo and the shell surface are marked with fine sculpture. The Maximum Height Index, the ratio of maximum height of the shell to its length used to distinguish mollusks, is about 50% for the species. The periostracum is olive-green in immature individuals and dark purple-brown in mature individuals.¹
