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.
Example sentences
  • 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).
