Entry from British & World English dictionary
Relating to fishes of an order (Perciformes) that comprises those resembling the perches. This is the largest vertebrate order and includes nearly half of all bony fishes.
- More derived taxa commonly possess fins located higher on the body, near the center of mass of the animal, with more vertically oriented insertions (e.g., perciform fishes).
- We expect pectoral-fin base orientation to show a more direct relationship to turning performance in taxa with similar body forms (e.g., short-bodied perciform fishes).
- For perciform fishes, the pectoral fin and tail are known to play important roles in propulsion and there is now a substantial literature on the function of these fins.
A perciform fish.
- Among basal taxa, for instance, Polypterus exhibits nearly vertically inclined pectoral fins; among perciforms, some labroid fishes show more horizontal fin bases.
- Primers designed to amplify and sequence the same genes of perciforms were useful in the present study.
Late 19th century: from modern Latin Perciformes (plural), from Latin perca 'perch' + forma 'shape'.
