Campellolebias
Campellolebias
Genus of fishes
Campellolebias is a genus of killifish in the family Rivulidae from southeast Brazil. They are restricted to seasonal blackwater pools in forests in coastal parts of Santa Catarina and São Paulo states.[1]
They are small fish, up to 5 cm (2.0 in) in total length.[2] Uniquely among killifish, Campellolebias and the closely related Cynopoecilus have internal fertilization. A part of the males' anal fin forms a "pseudo-gonopodium" that is used for inseminating the female.[1]
