Nandimitmacrodontiformes

Nandimitmacrodontiformes is a hypothetical order of ray-finned fishes, characterized by a proposed combination of specific morphological traits. While the name suggests a link to existing fish groups, particularly the Nandidae (leaf fishes) and the Macrodontinae (a subfamily within the catshark family), this taxonomic arrangement is not currently recognized in standard ichthyological classification. The term appears to originate from speculative or theoretical evolutionary models rather than established systematic research.

The proposed characteristics of Nandimitmacrodontiformes, as inferred from the name, might include a fusion of features seen in either freshwater perch-like fishes or certain cartilaginous fishes. This could encompass aspects of their skeletal structure, fin ray development, or dentition. However, without peer-reviewed scientific literature defining this order, its existence and defining characteristics remain speculative. Ichthyologists rely on phylogenetic analyses based on extensive genetic and morphological data to establish taxonomic orders. The absence of such evidence for Nandimitmacrodontiformes means it is not considered a valid scientific grouping. Further research or a theoretical framework proposing its evolutionary placement would be necessary for any formal consideration.
