The Chilodontidae, or headstanders, are a small family of freshwater characiform fishes found in northern and central South America. This family is closely related to Anostomidae and is sometimes treated as a subfamily, Chilodontinae, within the Anostomidae family. Due to issues of homonymy with the gastropod family Chilodontidae, one of the families must be changed, possibly by having the fish family revert to Eigenmann's original name of Chilodidae. See here for a discussion regarding this issue.
Chilodontids have colourful markings, making them popular in aquariums. They are small fish, all less than in adult length, and are distinguished by their habitual head-down postures.
Chilodontidae is the taxonomic name given to two families :
- Chilodontidae (gastropods), a family of gastropods from the order Neritoidea
- Chilodontidae (fishes), a small family of ray-finned fishes from the order Characiformes
Chilodontidae is a taxonomic family of mostly small deepwater sea snails, marine gastropod molluscs in the clade Vetigastropoda (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).
