Starfish
Starfish or sea stars are star-shaped echinoderms belonging to the class Asteroidea (). Common usage frequently finds these names being also applied to ophiuroids, which are correctly referred to as brittle stars or basket stars. Starfish are also known as asteroids due to being in the class Asteroidea. About 1,900 species of starfish live on the seabed in all the world's oceans, from warm, tropical zones to frigid, polar regions. They are found from the intertidal zone down to abyssal depths, at below the surface. Starfish are marine invertebrates. They typically have a central disc and usually five arms, though some species have a larger number of arms. The aboral or upper surface may be smooth, granular or spiny, and is covered with overlapping plates. Many species are brightly coloured in various shades of red or orange, while others are blue, grey or brown. Starfish have tube feet operated by a hydraulic system and a mouth at the centre of the oral or lower surface. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Echinasteridae
The Echinasteridae are a family of starfish in the monotypic order Spinulosida. The family includes eight genera and about 133 species found on the seabed in various habitats around the world. Taxonomy Echinasteridae contains eight genera and about 133 species. The two genera '' Echinaster'' and ''Henricia'' are the most speciose, forming species complexes. ''Echinaster'' has a largely tropical distribution and occurs in shallow seas including continental shelves, while ''Henricia'' is cosmopolitan, occurring mostly in cold waters, including polar habitats and abyssal locations. '' Aleutihenricia'' and '' Odontohenricia'' are native to the northeastern Pacific Ocean, in the vicinity of the Aleutian Islands. Characteristics Echinasterids are mostly five-armed starfish with thick but small discs, and long, slender, often cylindrical arms. The cuticle is covered on both the aboral (upper) and oral (lower) surfaces by a latticework of ossicles which are either flattened or rounded ...

Cape Of Good Hope
The Cape of Good Hope ( af, Kaap die Goeie Hoop ) ;''Kaap'' in isolation: pt, Cabo da Boa Esperança is a rocky headland on the Atlantic coast of the Cape Peninsula in South Africa. A common misconception is that the Cape of Good Hope is the southern tip of Africa, based on the misbelief that the Cape was the dividing point between the Atlantic and Indian oceans, and have nothing to do with north or south. In fact, by looking at a map, the southernmost point of Africa is Cape Agulhas about to the east-southeast. The currents of the two oceans meet at the point where the warm-water Agulhas current meets the cold-water Benguela current and turns back on itself. That oceanic meeting point fluctuates between Cape Agulhas and Cape Point (about east of the Cape of Good Hope). When following the western side of the African coastline from the equator, however, the Cape of Good Hope marks the point where a ship begins to travel more eastward than southward. Thus, the first mode ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
