La stupidità umana cambia target: dopo aver decimato la popolazione di squali mondiale, con più di 70 milioni di esemplari uccisi ogni anno per le pinne da mettere nella famigerata zuppa cinese ed un terribile impatto sull'ecosistema marino, il mercato ha cambiato obiettivo: mante e mobule sono ora in grave pericolo di estinzione.
Pare infatti che nelle credenze popolari cinesi, le loro branchie essiccate siano utilizzate per un' altra zuppa dell'orrore, considerata ottima per pulire il sangue dalle tossine e per abbassare la temperatura corporea.
Un kg di branchie essiccate viene valutato fino a 200 $, manna per le popolazioni di paesi quali India, Filippine, Indonesia. Solo pochi Paesi al mondo tutelano questi animali con leggi specifiche: Maldive, Ecuador, Hawaii ed alcune isole del Giappone.
Speriamo di non dover incontrare questi splendidi animali solo sui francobolli, come accaduto con il baniji, delfino cinese di acqua dolce, di cui ho parlato pochi giorni fa :-(

Slaughtered for the market place: Huge rise in ray hunting threatens ocean's 'gentle giants'
By Daily Mail Reporter
They are known as the ocean's gentle giants, but an alarming rise in manta and mobula ray hunting could threaten the very existence of the species.
From India to Ecuador, manta and mobula fishing has become big business for fisheries who are selling their gills to be used in soups and traditional Chinese medicine.
Conservationists have warned that demand could soon rival that of the controversial shark fin trade.
The rays are pulled from the ocean, either with fine gill nets or spears, and slaughtered to meet growing demand, mainly from the Chinese market.
Chinese practitioners believe the consumption of gills helps reduce toxins in the blood by purifying and cooling it, reducing body temperature and aiding blood circulation.
A belief that these gills boost the body's immune system, especially when swine and bird flu make daily headlines, has further boosted demand.
One kilogram of gill rakers from a mature Indonesian manta sells for up to $200 in the dried seafood markets of China.
Manta and mobula hunting has become big business because they are easy to catch.
But conservationists are concerned that because of overfishing the rays might be facing extinction before scientists are able to fully uncover all of the mysteries they hold.
A single fishing fleet can easily wipe out a local manta population in weeks or months, with little chance of stocks replenishing given their slow reproduction, limited local populations and lack of migration for some of the species.
Their slow maturation and reproductive cycles have raised serious concerns for the future of these species.

Growing demand for the manta and mobula rays, in part thanks to the loss of regional sharks, has transformed subsistence and localised fishing into a global, commercialised, export operation.
In some fishing villages in Indonesia alone, fishermen are catching more than 2,000 mantas each year.
In the Philippines, reports from the Bohol Sea region - a location where major manta fishing is centred - indicate that mantas are now rare in many places where they were once common.
No international laws and only a handful of national laws exist to prevent ray fishing.
Mantas are only protected in a handful of areas around the world including the Maldives, Hawaii, Ecuador and the Yaeyama Islands, Japan.
The manta ray is the largest of the all the rays.
They can grow up to 25ft across and weigh around 5,100lb.
They are mainly found in tropical waters and feed mostly on plankton, which is filtered into their bodies through their gills as swim.
Perfectly stream-lined for gliding through the water, the manta ray can reach speeds of up to 7mph.
They are often spotted swimming with divers and will sometimes surface alongside boats.
