〔动〕（与）鲈形目鱼（有关）的
Example sentencesExamples
- This perciform fish family is one of the most species-rich families of vertebrates with at least 1,300 and perhaps as many as 1,870 species.
- A similar lack of fossil records has also been suggested for perciform families, some teleostean orders, and mammalian and avian orders.
- 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.
- 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).

noun ˈpəːsɪfɔːm

A perciform fish.
Example sentencesExamples
- Primers designed to amplify and sequence the same genes of perciforms were useful in the present study.
- Among basal taxa, for instance, Polypterus exhibits nearly vertically inclined pectoral fins; among perciforms, some labroid fishes show more horizontal fin bases.

Origin

Late 19th century: from modern Latin Perciformes (plural), from Latin perca 'perch' + forma 'shape'.
