Researchers from the English Institute of Oceanography (IEO) have discovered a new species for science in the Marine Protected Area of \u200b\u200bEl Cachucho, a small crustacean that lives south of funds Bay of Biscay.
Inmaculada Frutos, researcher at the English Institute of Oceanography (IEO), and Jean Claude Sorbe, National Center for Scientific Research French (CNRS), recently published in the journal Zootaxa the taxonomic and ecological description of this new species: the Politolana sanchezi.
According to a report of the IEO, gathered by Europa Press, this small isopod crustacean is the third species that scientists described and published in the Marine Protected Area by the team Cachucho ECOMARG IEO research.
The crustacean is nearly an inch and lives in soft bottoms of the southern Bay of Biscay and west of Galicia, between 480 and 829 meters deep.
The small crustacean is capable of both buried in the mud to five inches deep, and swim above the bottom until at least more than one meter above the sediment. Displays a scavenger behavior and bioturbated, as observed in an experiment carried out with a pot trophic baited with fish and placed on a sled during a photogrammetric ECOMARG campaign.
The studied specimens were obtained during the French campaigns Essais and Prosecco and English Ecomarg04 Ecomarg03 and using different sampling devices (two types suprabenthic sled, a sled dredge photogrammetric and box-corer).
biodiversity hotspots
According highlights the IEO, the Cachucho is a "hot spot" of biodiversity where only talking about the group of crustaceans have been found more than 40 species are possibly new to science, and a density of organisms not mentioned elsewhere in the Bay of Biscay.
With this Three species are already described in almost three years of research. The process is quite slow, as it not only tries to describe the animal and its distinguishing features, but the results should be evaluated by the rest of the scientific community to be really sure that the species was not cited in other areas the planet.

Every three days, a new species in the Amazon
The extraordinary exuberance Amazon treasures many species. Only in the last ten years, the WWF has documented 1,200 new, one every three days.
The report "Amazon Lives: A decade of discovery 1999-2009" (pdf) contains the complete catalog: 637 plants, 257 fish, 216 amphibians, 55 reptiles, 16 birds and 39 mammals.
Some of them, as the Martialis Heureka, dubbed the "Ant from Mars" might have Prehistoric pedigree. The "ant from Mars" has a combination of characteristics never recorded earlier. It is a striking example predator and blind, 2 to 3 mm long, pale, no eyes, but with large jaws. The scientists found two years ago in Brazil: from the first new genus of living ants discovered since 1923.
in Iquitos (Peru), in primary forest, lowland rain, scientists spotted a frog with a color of fire in the head and legs with a pattern contrasting water.
Brazil and Peru are home to most of the Amazon Although there are eight countries that share the richest biodiversity on the planet, as Bolivia, Colombia, Ecuador, Guyana, Surinam and Venezuela joined them.
meat and biofuels
As biome Amazon covers 6.7 million square kilometers (45% of the land surface of South America, almost twice as Europe). Most of the region remains unexplored.
WWF warns that in the past 50 years, man has caused the destruction of 17% of tropical forests Amazon, an area larger than "two Spains". The reasons: the demand for beef, soya and biofuels, as deforested areas are occupied by cattle pastures.
Given the level of development of some countries, the organization has identified the need to advance in the definition of protected areas beyond national parks or reserves. "Governments, NGOs, scientists and civil society must redouble efforts to conserve the Amazon . Some of these species may have pharmacological application "asks Francisco Ruiz, one of the investigators.
