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)

The five rockets are in the project report stage and would come into operation in the future, said N Sudheer Kumar, Director, Capacity Building Programme Office (CBPO), Indian Space Research Organisation (ISRO).

The Indian space agency is working on a fleet of medium to heavy lift rockets with a carrying capacity ranging from 4.9 ton to 16.3 ton, said a senior official. The five rockets are in the project report stage and would come into operation in the future, said N Sudheer Kumar, Director, Capacity Building Programme Office (CBPO), Indian Space Research Organisation (ISRO). He was speaking at the International Space Conference and Exhibition, organised by Confederation of Indian Industry (CII) in virtual mode recently. When that happens ISRO can not only launch its own communication satellites but also enter the global communication satellite launch market.

Kumar also said ISRO is working on upgrading Geosynchronous Satellite Launch Vehicle-Mk III (GSLV-Mk III) which can carry up to four ton to Geo Transfer Orbit (GTO). Normally rockets eject the communication satellites into GTO. From GTO the satellites will be taken to geostationary orbit by firing their engines. India uses Ariancespace's Ariane rocket to orbit its communication satellites weighing over four ton. According to Kumar, ISRO is also working on upgrading the lifting capacity of GSLV-Mk III to six ton and 7.5 to GTO.

Kalamkari painting on a cotton cloth

In the recent past, Kalamkari has suddenly gained prominence in the wardrobes of Indian women. Commercial hubs in the city are filled with mannequins posing in kalamkari blouses, or sarees stretching out for yards on hangers.

As the name suggests, 'kalamkari' means 'craft from a pen'. Artisans draw on cloth with a pen, and colour it in with paints. This art form originated from the Mughal era and many of the scenes that artists choose to draw are scenes from Mughal gardens or palaces.
