Hidden in one of Australia's most developed and fastest growing areas lives one of the world's smallest freshwater crayfish species. Robert B McCormack the Team Leader for the Australian Crayfish Project described the new species belonging to the genus Gramastacus, after 8 years of research in the swamps and creeks of coastal New South Wales, Australia. The study was published in the open access journal ZooKeys.

Being a small crayfish species it has remained undescribed and undiscovered in one of the fastest developing regions of Australia. Only one other species of Gramastacus crayfish is known and it occurs some 900 km away in the Grampians region of Victoria.

This new species is found in lowland ephemeral habitats surrounding coastal lakes and lagoons from Wamberal Lagoon, north along the coastal strip to Wallis Lake. Being dependent on regular natural flooding and drying cycles, only lowland, swampy areas are suitable for this tiny crayfish.

Each crayfish digs a small rounded cross-section burrow up to one metre deep into the water table to survive the drying cycle. Some areas are riddled with these small burrows as they are a very prolific species and can occur in very high numbers in small habitat areas.

The newly described crayfish are found in one of Australia's most developed regions.

Unfortunately, this means that much of their habitat has been lost in the past as these ephemeral areas are the first to be drained or reclaimed to make way for agriculture, industry, housing developments, golf courses, infrastructure, etc. Now, being found and officially described, this crayfish must be considered in any further developments and hopefully future habitat loss will be reduced.

The scattered populations of Gramastacus seem highly fragmented and many are increasingly threatened by a range of risks other than human development. Invasive crayfish, pest fish species like plague minnows and swordtails, rising sea levels and falling water tables all are increasing dangers.

Luckily, the large number of National Parks and Reserves along the coastal strip provides safe refuges for some populations.

Death, tumors harm efforts to save rare rhinos
Washington (AFP) April 04, 2014
Efforts to save critically endangered Sumatran rhinoceroses were dealt a double blow this week with the death of one animal at a US zoo and the discovery of reproductive tumors in another. There are just 100 Sumatran rhinos left in the wild in their native lands of Indonesia and Malaysia, and nine are held in captivity for breeding purposes. The lumbering creatures have dwindled rapidly ... read more
