Maltese Skate
The Maltese skate (''Leucoraja melitensis''), or Maltese ray, is a species of fish in the family Rajidae. It is a rare endemic species from the Mediterranean Sea found in the coastal waters of Algeria, Italy, Malta, Tunisia, Greece and Turkey. Its natural habitat is open seas. It is threatened by habitat loss. Sustainable consumption In 2010, Greenpeace, Greenpeace International added the Maltese skate (''Leucoraja melitensis'') to its seafood red list. "The Greenpeace International seafood red list is a list of fish that are commonly sold in supermarkets around the world, and which have a very high risk of being sourced from unsustainable fisheries."

Robert Clark (zoologist)
Dr Robert Selbie Clark (11 September 1882 – 29 September 1950) was a Scottish marine zoologist and explorer. He was the biologist on Sir Ernest Shackleton's Imperial Trans-Antarctic Expedition of 1914–1917, and served as the director of the Scottish Home Department Marine Laboratory, at Torry, Aberdeen. Early life Robert Clark was born on 11 September 1882 in Aberdeen, the son of William Clark. He attended Aberdeen Grammar School and then Aberdeen University from where he graduated with an M.A. in 1908. In 1911 he attained a BSc and became Zoologist to the Scottish Oceanographical Laboratory, Edinburgh, a post he held until he was appointed naturalist to the Marine Biological Association in 1913. While at the Scottish Oceanographical Laboratory, he worked on some of the Antarctic specimens that William Speirs Bruce had brought back from the Scottish National Antarctic Expedition of 1902–04. He was a natural sportsman, a keen golfer and angler, and was selected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Mediterranean Sea
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide. The Mediterranean Sea e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Greenpeace
Greenpeace is an independent global campaigning network, founded in Canada in 1971 by Irving Stowe and Dorothy Stowe, immigrant environmental activists from the United States. Greenpeace states its goal is to "ensure the ability of the Earth to nurture life in all its diversity" and focuses its campaigning on worldwide issues such as climate change, deforestation, overfishing, commercial whaling, genetic engineering, and anti-nuclear issues. It uses direct action, lobbying, research, and ecotage to achieve its goals. The network comprises 26 independent national/regional organisations in over 55 countries across Europe, the Americas, Africa, Asia and the Pacific, as well as a co-ordinating body, Greenpeace International, based in Amsterdam, the Netherlands. The global network does not accept funding from governments, corporations, or political parties, relying on three million individual supporters and foundation grants.

Leucoraja
''Leucoraja'' is a genus of hardnose skates in the family Rajidae, commonly known as the rough skates.
