In the present cladistic analysis, the representatives of these four osteoglossomorph families (Hiodon: Hiodontidae; Pantodon: Osteoglossidae
; Xenomystus: Notopteridae; Mormyrus: Mormyridae) do appear grouped in a monophyletic clade (C8), which is supported by the three unambiguous synapomorphies listed above but is not supported by a bootstrap value [right arrow] 50% (Fig.
The different colour varieties of the Asia arowana Scleropages formosus (Osteoglossidae) are distinct species: morphology and genetic evidences.
Rapid isolation and characterization of microsatellites from the genome of Asian arowana (Scleropages formosus, Osteoglossidae, Pisces).
Teleost fishes make up the most diverse group among the vertebrates, encompassing an estimated 20,000 living species divided into approximately 38 orders (Richter et al., 2000), among them that of the Osteoglossiforms, which comprise two families, the Osteoglossidae
and the Pantodontidae.
These include families Osteoglossidae
, Anabantidae, Chanidae, Schilbedae, Cyprinidae, Mormyridae, Cichlidae, Mochokidae, Characidae, Bagridae and Clariidae (Table 1).
Analysis of catch in the preliminary survey of the fresh water fish of Nigeria by Welman, 1948, revealed that Kaduna and Sokoto/Rima rivers have Mochokidae, 28, and Osteoglossidae
, 22, species respectively in them.
