Where do osteoglossomorph fishes live around the world?

Osteoglossomorphs are primarily freshwater fishes distributed across various continents, with their specific ranges depending on the order and family.12

Distribution by Order

• Osteoglossiformes: These diverse fishes are found in tropical freshwater environments across Africa, Asia, South America, Australia, and islands of the tropical Pacific Ocean. Some species may occasionally inhabit slightly brackish water.12

  • The Mormyridae and Gymnarchidae families are restricted to Africa.1
  • Notopteridae (featherbacks) are located in Africa, Southeast Asia, and India.1
  • Osteoglossidae (bony tongues) are found in Africa, South America, and Australasia, a distribution pattern often attributed to the ancient supercontinent of Gondwana.1

• Hiodontiformes: This group is much more limited in range, occurring exclusively in North America. It is represented by only two species, the goldeye and the mooneye.12
