New Freshwater crab species discovered in Chinese Fish market by Researchers

Being a primarily aquatic species, the new crab prefers the pools of limestone hill streams, therefore its name Yuebeipotamon calciatile, where calciatile means 'living on limestone'

BEIJING, September 8, 2016: An examination of the ornamental fish market in southern China has led to the discovery of a new species and even a new genus of freshwater crab, researchers have reported.

Knowing about the growing demand for eye-catching freshwater crabs from southern China, the authors took a look at the ornamental fish market to eventually identify an individual with unusually structured male gonopod, which in crustaceans is a swimming appendage modified to serve as a reproductive organ.

Despite the superficial resemblance to an already existing freshwater crab genus, at second glance, the crab turned out to be quite distinct thanks to a unique set of features including the carapace, the monopod and the relatively long and slender legs.
Once the molecular analyses’ results were also in, the authors had enough evidence to assign the freshwater crab as a species and even a genus new to science.

Being a primarily aquatic species, the new crab prefers the pools of limestone hill streams, therefore its name Yuebeipotamon calciatile, where calciatile means ‘living on limestone’.

To adapt to the habitat, the species seems to have developed its characteristic slender legs, which make it easier for the crab to climb and move around whenever the short-lived limestone hill streams make it search for a new home, the researchers reported in the journal ZooKeys.

The carapace of the new crab is usually coloured in maroon to dark brown, while the claws and legs are reddish to purplish, the study said. (IANS)

  • This December, China witnessed a slow rate of it’s industry expansion.
  • The service sector is growing whereas the manufacturing sector is bearing the brunt of the slowed pace.

Chinese manufacturing sector activity expanded at a slower pace in December while the service sector continued its growth, according to the Purchasing Managers’ Index (PMI).

The PMI of China’s manufacturing activity was released on Sunday. It stood at 51.6 points in December, down from 51.8 in November, Efe news quoted the figures released by the National Bureau of Statistics (NBS) as saying.

 In contrast, the service sector activity grew to stand at 55 points in December as compared to 54.8 in November.

A figure above 50 points suggests expansion while a figure lower than 50 indicates contraction. The service sector already accounts for more than half of China’s gross domestic product.

The December figure for the manufacturing index was at par with the annual average, which points to strong resilience in China’s growth, according to NBS statistician Zhao Qinghe. IANS
