Pot assolir els 65 cm de longitud total[2] (encara que la seua mida normal és de 40,7)[3] i els 2.940 g de pes.[4][5]
Alimentació
Els alevins de menys d'1,2 cm de llargada es nodreixen de plàncton i d'altres petits invertebrats i quan arriben a fer entre 1,6 i 1,8 cm comencen a alimentar-se d'organismes bentònics. Com a adult, es desplaça a aigües poc fondes al voltant de l'ortus i de l'ocàs per a menjar.[6]
