| Evidence of Cetacean EvolutionTue, 02 Dec 2008 13:43:34 -0800 by MrBiologicalA clip from Macmillian Publishers Ltd. 2007© As Seen On the World Wide WebEvidence of Cetacean Evolution Summary: The cetaceans (whales, dolphins and porpoises) are descendants of land-living mammals. Their terrestrial origins are specifically indicated by their need to breathe air from the surface; The bones of their fins, which resemble the jointed hands of land mammals; and The vertical movement of their spines, characteristic more of a running mammal than of the horizontal movement of fish. The question of how land animals evolved into ocean-going leviathans had been a mystery for a long time, owing to gaps in the fossil record. However, recent discoveries in Pakistan have managed to solve many of these mysteries, and it is now possible to see several stages in the transition of the cetaceans from land to sea.[Recommend Reading]Evolution of Cetaceanshttp://en.w ikipedia.org/wiki/Wh ale_evolution [Re-Uploaded for Educational Purposes]Click Link Below for [PLAYLIST]http://www .youtube.com/profile _play_list?user=MrBi ological Related: cetaceans evolution whale mammal aquatic life marine dolphins porpoises pakistan fossil record |

| Tai Chi - The Siamese Algae Eater! Comedor de Alga SiamesTue, 02 Dec 2008 00:26:47 -0800 by athenathon77No video o Tai Chi, comedor de alga Siames. Garantia de aquario limpo e sem algas (problema de algas marrons pentelhas).Comedor de Alga Siamês Nome Científico: Crossocheilus siamensis Família: Ciprinídeos Origem: Sudeste Asiático pH: 6,8 a 7,2 Comportamento: Pacífico, porém territorial com os da mesma espécie. Sociabilidade: Sozinho ou em grupo Alimentação: Aceita bem flocos e alimentos congelados. Temperatura: 25 a 28º C DH: Baixa Tamanho: Normalmente 8 cm, mas há quem diga que chega a alcançar até 15cm. Aquário: 150LOs comedores de algas siameses (tailandeses)O verdadeiro comedor de algas siamês, Crossocheilus siamenensis, é o único peixe que se conhece capaz de comer algas vermelhas e não se encontra facilmente no mercado, com a agravante de haver cinco espécies bastante semelhantes sendo o comedor de algas chinês, Gyrinocheilus aymonieri o mais vulgarmente encontrado nas lojas da especialidade o qual se distingue por não ter barbelas, sendo também o mais agressivo de todos. Crossocheilus siamensis, is a species of freshwater fish in the carp family, Cyprinidae. This bottom-dwelling tropical fish is found in mainland Southeast Asia that includes the Chao Phraya and Mekong basins as well as the Malay Peninsula. Their natural habitats are streams and rivers as well as flooded forests during the rainy season. The Siamese algae eater should not be confused with the Flying fox (Epalzeorhynchos kalopterus) or the False siamensis (Garra cambodgiensis).The Siamese algae eater (Epalzeorhynchos siamensis or Crossocheilus siamensis) has a black horizontal stripe extending from opercle to tail. The genuine Epalzeorhynchos siamensis alias Crossocheilus siamensis without maxillary barbels and with deeply fringed V-shaped upper lip[1][2] is rarely encountered in the aquarium trade. [3]Closely related is the Red-algae eater Crossocheilus langei, a species that is widely sold as the Siamese algae eater. It has a bright brownish elongate body with a slighly flat belly. It has a prominent brown-black horizontal stripe extending from nose to tail. This fish may grow up to the length of 16 centimeters. It possesses small maxillary barbels and an unfringed shallowly arcuate upper lip.[4] Two other similar species are traded as Siamese algae eaters, namely Crossocheilus atrilimes,[5] a species that likes to eat Java moss rather than red algae, and an undescribed species of Crossocheilus.The Siamese algae eater is also known as the Siamese flying fox, Flying fox and Siamese fox. It is common in aquarium stores and a very good algae eater. A very similar species, Garra taeniata aka Epalzeorhynchus sp, is sometimes sold as Siamese algae eater which have earned that species the common name False siamese algae eater. A majority the Siamese algae eaters that are (or at least used to be) sold in United States are in fact False Siamese algae eaters. It is also common for shipments of Siamese algae eater to contain both Siamese algae eaters and False Siamese algae eater. This is not surprising as the species live in the same areas and young specimens of the two species school together. You can tell the two species apart by the following facts:The black horizontal band doesn't go all the way to the tail fin on a False Siamese algae eater.There is a narrow lighter band above the black band in a False Siamese algae eater.The dorsum of the False Siamese algae eater is solid grayish brownAll fins on a false Siamese algae eater are yellowish in color except for the pectorals.The mouth of a false Siamese algae eater resembles a pink ring.False Siamese algae eaters have two set of barbles.

| Descripción de Lanzamiento de Proyectil (Video 1)Mon, 01 Dec 2008 12:44:27 -0800 by daelaqteActividad para la medición del ángulo de inclinación con respecto a la horizontal de una manguera. Para este caso, notar que el timbre permite facilitar con la ayuda de la lámpara estroboscópica el intervalo de cada gota de agua que cae describiendo una trayectoria proyectil con respecto a una altura de referencia. Si quisieramos calcular el ángulo de inclinación con respecto a la horizontal, ¿De qué factores crees que depende? Related: observación del lanzamiento de proyectil |
