Ahvenalised (Perciformes)

Kõige suurem kalade ja selgroogsete selts, mis kuulub ahvenalaadsete (Percomorpha) ülemseltsi, kiiruimsete klassi. Ahvenaliste hulka kuulub 40% kõigist kaladest, kokku üle  10 000 liigi.

Seljauimi on enamasti 2 ja eesmine koosneb ogakiirtest; kõhuuimed, kui nad on olemas, asetsevad tavaliselt rinnauimede all või nendest eespool - kõril ning ei sisalda enamasti üle kuue kiire. Rinnauimede alused asetsevad kala pikitelje suhtes kaldu või perpendikulaarselt. Ogajad on ka pärakuuime esimesed uimekiired. Rasvauim puudub. Saagsoomused. Ujupõis ei ole ühendatud sooltoruga või puudub hoopis. Paarkümmend alamseltsi, suurimaks neist pärisahvenalised (Percoidei) ja umbes 160 sugukonda.
