Palinurus Barbarae
''Palinurus barbarae'' is a species of spiny lobster described in 2006, which was found by fishermen working the waters above the Walters Shoals, a series of submerged mountains south of Madagascar. The animal weighs and reaches up to long excluding the long antennae, and is similar to '' P. delagoae'', found off South Africa, from which it may be differentiated by a number of characters including the larger number of spines. There are fears that the species, which lives in an area outside any country's jurisdiction, may now be exploited, or that it has already been brought near to extinction by overfishing Overfishing is the removal of a species of fish (i.e. fishing) from a body of water at a rate greater than that the species can replenish its population naturally (i.e. the overexploitation of the fishery's existing Fish stocks, fish stock), resu ....

Walters Shoals
The Walters Shoals is a group of submerged mountains off the coast of Madagascar. The shoals are south of Cape Sainte Marie - Madagascar and east of Richards Bay at the African coast. The tips of some of the mountains are only below the surface. The Walters Shoals is home to many species of fish, crustaceans, and mollusks and is considered as a Ecologically or Biologically Significant Area. Groups of Barau's petrel (''Pterodroma baraui'') forage the area during their breeding season. It was discovered in 1963 by the South African Hydrographic Frigate SAS ''Natal'' captained by Cmdr Walters. When found it had a huge population of Galápagos shark The Galapagos shark (''Carcharhinus galapagensis'') is a species of requiem shark, in the family Carcharhinidae, found worldwide.

Seamount
A seamount is a large submarine landform that rises from the ocean floor without reaching the water surface (sea level), and thus is not an island, islet, or cliff-rock. Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to in height. They are defined by oceanographers as independent features that rise to at least above the seafloor, characteristically of conical form.IHO, 2008. Standardization of Undersea Feature Names: Guidelines Proposal form Terminology, 4th ed. International Hydrographic Organization and Intergovernmental Oceanographic Commission, Monaco. The peaks are often found hundreds to thousands of meters below the surface, and are therefore considered to be within the deep sea. During their evolution over geologic time, the largest seamounts may reach the sea surface where wave action erodes the summit to form a flat surface. After they have subsided and sunk below the sea surface, such flat-top ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madagascar
Madagascar, officially the Republic of Madagascar, is an island country that includes the island of Madagascar and numerous smaller peripheral islands. Lying off the southeastern coast of Africa, it is the world's List of islands by area, fourth largest island, the List of island countries, second-largest island country, and the List of countries and dependencies by area, 46th largest country overall. Its capital and List of cities in Madagascar, largest city is Antananarivo. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from Africa during the Early Jurassic period, around 180 million years ago, and separated from the Indian subcontinent approximately 90 million years ago. This isolation allowed native plants and animals to evolve in relative seclusion; as a result, Madagascar is a biodiversity hotspot and one of the world's 17 megadiverse countries, with over 90% of its wildlife of Madagascar, wildlife being endemic. The island has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

As of 2012, the ''Argus'' had a daily readership of 294000, according to the South African Advertising Research Foundation's All Media Products Survey (Amps) Newspaper Readership and Trends. Its circulation for the first quarter of 2013 was 33247. Jermaine Craig is the executive editor of the ''Cape Argus''. He replaced Gasant Abarder, who resigned in early 2013 to take up a post at Primedia in the Western Cape.

Antenna (biology)
An antenna (plural: antennae) is one of a pair of appendages used for Sensory system, sensing in arthropods. Antennae are sometimes referred to as ''feelers''. Antennae are connected to the first one or two Segmentation (biology), segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments. While they are typically sensory organs, the exact nature of what they sense and how they sense it is not the same in all groups. Functions may variously include sensing tactition, touch, air motion, heat, vibration (sound), and especially insect olfaction, smell or gustation, taste. Antennae are sometimes modified for other purposes, such as mating, brooding, swimming, and even anchoring the arthropod to a substrate (biology), substrate. Larval arthropods have antennae that differ from those of the adult. Many crustaceans, for example, have free-swimming larvae that use their antennae for swimming. Antennae can also locate other group members i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palinurus Delagoae
Palinurus (''Palinūrus''), in Roman mythology and especially Virgil's ''Aeneid'', is the coxswain of Aeneas' ship. Later authors used him as a general type of navigator or guide. Palinurus is an example of human sacrifice; his life is the price for the Trojans landing in Italy. Palinurus in the ''Aeneid'' In Book 3, which tells of the Trojans' wanderings after The Fall of Troy, he is singled out as an experienced navigator. In Book 5, when the Trojans have left Carthage, he advises Aeneas to forestall sailing to Italy and to wait out a terrible storm on Sicily, where they hold the funeral games honoring Aeneas's father, Anchises. After they leave Sicily for Italy, Palinurus, at the helm of Aeneas's ship and leading the fleet, is singled out by Virgil in second person when it becomes clear that he is the one whom the gods will sacrifice to guarantee safe passage to Italy for the Trojans: ''unum pro multis dabitur caput'', "one single life shall be offered to save many."

International Waters
The terms international waters or transboundary waters apply where any of the following types of bodies of water (or their drainage basins) transcend international boundaries: oceans, large marine ecosystems, enclosed or semi-enclosed regional seas and estuaries, rivers, lakes, groundwater systems (aquifers), and wetlands. "International waters" is not a defined term in international law. It is an informal term, which sometimes refers to waters beyond the "territorial sea" of any country. In other words, "international waters" is sometimes used as an informal synonym for the more formal term "high seas", which under the doctrine of ''mare liberum'' (Latin for "freedom of the seas"), do not belong to any state's jurisdiction. As such, states have the right to fishing, navigation, overflight, laying cables and pipelines, as well as scientific research. The Convention on the High Seas, signed in 1958, which has 63 signatories, defined "high seas" to mean "all parts of the sea ...

Overfishing
Overfishing is the removal of a species of fish (i.e. fishing) from a body of water at a rate greater than that the species can replenish its population naturally (i.e. the overexploitation of the fishery's existing Fish stocks, fish stock), resulting in the species becoming increasingly underpopulated in that area. Overfishing can occur in water bodies of any sizes, such as ponds, wetlands, rivers, lakes or oceans, and can result in resource depletion, reduced biological growth rates and low biomass (ecology), biomass levels. Sustained overfishing can lead to critical depensation, where the fish population is no longer able to sustain itself. Some forms of overfishing, such as the Threatened sharks, overfishing of sharks, has led to the upset of entire marine ecosystems. Types of overfishing include growth overfishing, recruitment overfishing, and ecosystem overfishing. Overfishing not only causes negative impacts on biodiversity and ecosystem functioning, but also reduces fish pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
