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.
Mayo has or used to have 31 threatened animals within its boundaries. One of them is me, the Murray Hardyhead.
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.

It has a small mouth with protrusible lips, a restricted gape, and a single row of small teeth on the anterior part of both jaws.The species is usually found in schools of distinct size classes: juveniles are found throughout lakes, in open areas associated with edge structure; and adults have been observed over shallow habitats including open sand banks.¹
