Australopoda
Scientific name
Australopoda
Keiler , Richter & Wirkner , 2016

The Australopoda form a taxon of the mean crayfish . They include the taxa Lomisoidea , Aegloidea and Chirostyloidea . The name “Australo-” (southern) and “-poda” (-füßer) is derived from the distribution of Lomisoidea and Aegloidea, which is limited to the southern hemisphere.

features

The members of the Australopoda are characterized by a crab-like shape, which, however, was created independently of that of the crabs (Brachyura) by a reduction of the pleon within the medium-sized crabs .

Way of life

The cancer groups that have been combined to form the Australopoda have very different ways of life. What they have in common is that all species live in the southern hemisphere . Some species are marine, others live in fresh water, such as Aegla cholchol, which belongs to the Aeglidae . The Yeti crab ( Kiwa hirsuta ) belonging to the Kiwaidae , on the other hand, specializes in life in the hydrothermal fields of the deep sea .

Systematics

These were described and established in 2016 by Jonas Keiler , Stefan Richter and Christian S. Wirkner from the University of Rostock .

The Australopoda are divided into three superfamilies with five families:
