Ectrepopterus
''Ectrepopterus uruguayensis'' is a small species of characin originally recorded only from streams in Uruguay, with occasional sightings in Brazil and Argentina. It is the only known member of the genus ''Ectrepopterus'', which was formerly a subgenus of ''Megalamphodus'' (now known as ''Hyphessobrycon''). Given its restricted range, it is considered a rare fish, and is of note for conservation researchers interested in preserving the biodiversity of the region. A small fish with silvery-gold scales and yellow fins, ''E. uruguayensis'' is characterized by a variety of features, including an incomplete lateral line and eyes wider than the snout is long. Something of particular note is the presence of bony hooks on the fin-rays of the pectoral fin, which is unusual for a characin; other members of Characidae may display these hooks on the pelvic or anal fins, but the pectoral fin is an uncommon location. ''E. uruguayensis'' can be found living in syntopy with other characids in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Characidae
Characidae, the characids or characins is a family of freshwater subtropical and tropical fish, belonging to the order Characiformes. The name "characins" is the historical one, but scientists today tend to prefer "characids" to reflect their status as a by and large monophyletic group at family rank. To arrive there, this family has undergone much systematic and taxonomic change. Among those fishes that remain in the Characidae for the time being are the tetras, comprising the very similar genera ''Hemigrammus'' and ''Hyphessobrycon'', as well as a few related forms such as the cave and neon tetras. Fish of this family are important as food and also include popular aquarium fish species. These fish vary in length, though many are less than . One of the smallest species, ''Hyphessobrycon roseus'', grows to a maximum length of 1.9 cm. These fish inhabit a wide range and a variety of habitats. They originate in the Americas, ranging from southwestern Texas and Mexico through ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Weed Fowler
Henry Weed Fowler (March 23, 1878 – June 21, 1965) was an American zoologist born in Holmesburg, Pennsylvania. He studied at Stanford University under David Starr Jordan. He joined the Academy of Natural Sciences in Philadelphia and worked as an assistant from 1903 to 1922, associate curator of vertebrates from 1922 to 1934, curator of fish and reptiles from 1934 to 1940 and curator of fish from 1940 to 1965. He published material on numerous topics including crustaceans, birds, reptiles and amphibians, but his most important work was on fish. In 1927 he co-founded the American Society of Ichthyologists and Herpetologists and acted as treasurer until the end of 1927. In 1934 he went to Cuba, alongside Charles Cadwalader (president of the Academy of Natural Sciences of Philadelphia), at the invitation of Ernest Hemingway to study billfishes, he stayed with Hemingway for six weeks and the three men developed a friendship which continued after this trip and Hemingway sent speci ...

Curimatidae
The Curimatidae, toothless characins, are a family of freshwater fishes, of the order Characiformes. They originate from southern Costa Rica to northern Argentina. The family has around 105 species, many of them frequently exploited for human consumption. They are closely related to the Prochilodontidae. This family lacks jaw teeth, although they do sometimes have small teeth on their pharyngeal plates. They eat films of slime coating underwater surfaces, which consist largely of algae, zooplankton and detritus. It has been suggested that feeding behavior of some species like ''Psectrogaster essequibensis'' may change its diet pattern in function of the sediment content of the water, showing a regime mainly based on algae in waters with high sediment load, until an omnivorous or detritivore regime in waters with low sediment load. Classification The family has eight genera and around 105 species: Family Curimatidae * '' Curimata'' (13 species) * ''Curimatella'' (five species) ...
