Alligator Gar
The alligator gar (''Atractosteus spatula'') is a ray-finned euryhaline fish related to the bowfin in the infraclass Holostei . It is the largest species in the gar family, and among the largest freshwater fish in North America. The fossil record traces its group's existence back to the Early Cretaceous over 100 million years ago. Gars are often referred to as " primitive fishes", or "living fossils" because they have retained some morphological characteristics of their early ancestors, such as a spiral valve intestine, which is also common to the digestive system of sharks, and the ability to breathe both air and water. Their common name was derived from their resemblance to the American alligator, particularly their broad snouts and long, sharp teeth. Anecdotal evidence suggests that an alligator gar can grow up to in length. The body of an alligator gar is torpedo-shaped, usually brown or olive, fading to a lighter gray or yellow ventral surface. In very rare occurrence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Atractosteus Tropicus
The tropical gar (''Atractosteus tropicus'') is a species of fish from Central America, where it is found in the Pacific and Atlantic drainages from southern Mexico to Costa Rica. In Central America it is known as ''gaspar'' and in Mexico it is known as ''pejelagarto'', a contraction of the words "pez" (fish) and "lagarto" (alligator). This gar inhabits a wide range of fresh and brackish water habitats such as rivers, floodplains, lakes and pools, but avoids areas with a strong current. It reaches lengths of up to (although typically less than half that length) and a weight up to . The tropical gar looks very similar to the longnose gar in color and markings, but can be distinguished by its shorter, broader snout. The tropical gar's diet consists mainly of cichlids and other fish. While gar are not widely eaten, there is a traditional Tabasco Tabasco (), officially the Free and Sovereign State of Tabasco ( es, Estado Libre y Soberano de Tabasco), is one of the 32 Federal Ent ...

Bernard Germain De Lacépède
Bernard-Germain-Étienne de La Ville-sur-Illon, comte de Lacépède or La Cépède (; 26 December 17566 October 1825) was a French naturalist and an active freemason. He is known for his contribution to the Comte de Buffon's great work, the ''Histoire Naturelle''. Biography Lacépède was born at Agen in Guienne. His education was carefully conducted by his father, and the early perusal of Buffon's Natural History ('' Histoire naturelle, générale et particulière'') awakened his interest in that branch of study, which absorbed his chief attention. His leisure he devoted to music, in which, besides becoming a good performer on the piano and organ, he acquired considerable mastery of composition, two of his operas (which were never published) meeting with the high approval of Gluck; in 1781–1785 he also brought out in two volumes his ''Poétique de la musique''. Meantime he wrote two treatises, ''Essai sur l'électricité'' (1781) and ''Physique générale et particuliè ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
