X-ray fish

Description

Pristella is a genus of fish in the family Characidae. It was formerly a monotypic taxon only containing Pristella maxillaris, but in 2019 a second species, Pristella ariporo, was described. Until 2019, Pristella was a monotypic genus, but P. ariporo was described in 2019. Additionally, Hyphessobrycon axelrodi may belong in Pristella due to its conical teeth, but further genetic studies are needed to confirm this.
