The entire family is like a bunch of Darwin's finches. The predators of fish and squid have four big fangs. The eaters of tiny crustaceans and algae eaters have a comb of needles, and the predators of limpets and clams have incisors and molars (Take a look also to the grinding teeth like cobblestones at the bottom of the mouth).

More like Darwin's finches if designed by H.G. Giger. Cant say that I'd recommend googling "sparidae teeth".
