Type Locality



E. fossor has the widest distribution of all endemic Engaeus species in Tasmania. Although the species is found on Hunter Is., it is not present in the extensive collections of freshwater crayfish from King Is.


E. fossor occupies burrows of type 2 habitats almost exclusively; it has only rarely been found in burrows which are independent of the water-table or in burrows in permanent water. It can be found in habitats of a wide variety of vegetation types. For instance, in the north-west region of Tasmania it is found in the vast swamps dominated by blackwood (Acacia melanoxylon), or in tea-tree swamps associated with small creeks, or in coastal plains (where Geocharax sp. occurs in the permanently wet areas); elsewhere it can be located in buttongrass plains (with Parastacoides sp.), in wet sclerophyll forest or Nothofagus cunninghammi rainforest (for instance at the Lower Gordon River and at the type locality for E. cisternarius).

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
