Sifundvo lesimayelana netimfishi sibitwa ngekutsi yi-ichthyology.Kunetinhlobo tenhlanti letingetulu kwa 33 000 letikhona, lelicembu lelikhulu kunawo onkhe emacembu etilwane letinemgogodla futsi letendlula tonkhe letinye tinhlobo tetinhlobo letindzala, letifaka ekhatsi tilwane letihlala emantini, tilwane letihamba ngesisu, tinyoni kanye netilwane letinetimfishi, tihlanganisiwe. Tinhlanti letiningi tiyincenye yelicembu le Actinopterygii, timfishi letinemaphiko, lekuyintfo leyenta cishe hhafu wato tonkhe tilwane letinemgogodla letiphilako.[2]
