Longsnout Distichodus
The longsnout distichodus (''Distichodus lusosso'') is an African characin in the family Distichodontidae The Distichodontidae are a family of African freshwater fishes of the order Characiformes. Two evolutionary grades are found in this family; micropredators (predators of very small organisms like aquatic insect larvae) and herbivores have a nonp .... Description It is a relatively large and well-built fish, attaining a maximum length of . The body is a golden colour (most prominent in juveniles) with several vertical dark bands. Its back is well-arched, and it has reddish fins. The most defining feature of this species is its particularly long head, from which it earns its name.

Characin
Characiformes is an order of ray-finned fish, comprising the characins and their allies. Grouped in 18 recognized families, more than 2000 different species are described, including the well-known piranha and tetras.; Buckup P.A.: "Relationships of the Characidiinae and phylogeny of characiform fishes (Teleostei: Ostariophysi)", ''Phylogeny and Classification of Neotropical Fishes'', L.R. Malabarba, R.E. Reis, R.P. Vari, Z.M. Lucena, eds. (Porto Alegre: Edipucr) 1998:123-144. Taxonomy The Characiformes form part of a series called the Otophysi within the superorder Ostariophysi. The Otophysi contain three other orders, Cypriniformes, Siluriformes, and Gymnotiformes. The Characiformes form a group known as the Characiphysi with the Siluriformes and Gymnotiformes. The order Characiformes is the sister group to the orders Siluriformes and Gymnotiformes, though this has been debated in light of recent molecular evidence. Originally, the characins were all grouped within a sing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distichodontidae
The Distichodontidae are a family of African freshwater fishes of the order Characiformes. Two evolutionary grades are found in this family; micropredators (predators of very small organisms like aquatic insect larvae) and herbivores have a nonprotractile upper jaw and a deep to shallow body, while carnivores have a movable upper jaw and an elongated body. Although the herbivores primarily feed on plant material, these species often have omnivorous tendencies. The carnivores include specialized fish-eaters (genus ''Mesoborus''), fin-eaters (''Belonophago'', ''Eugnathichthys'' and ''Phago'') and species that will feed on both whole fish and fins (''Ichthyborus''). The fin-eaters attack other fish, even ones that are much larger, where they bite off pierces of fins with their sharp teeth. The fish in Distichodontidae vary greatly in size among species, with the smallest micropredators being less than in length, and the largest herbivores can reach up to . Genera The 17 genera i ...
