Durophagous fish consume a diet based primarily on hard-shelled animals, mainly
mollusks. In order to successfully perform this task, they are equipped with an extra set of …

We examine the structure of the bone of the pharyngeal jaws of a large fish, the black drum
(Pogonias cromis), that uses its tooth-jaw complex to crush hard-shelled bivalve mollusks …

Mollusks such as snail and mussels adopt hard shells to protect their vulnerable bodies.
Recent studies on biomaterials have revealed that these shells especially the nacre layers …

With an exclusive diet of hard-shelled mollusks, the black drum fish (Pogonias cromis)
exhibits one of the highest bite forces among extant animals. Here we present a systematic …

Parrotfish are common fish found in tropical and sub-tropical waters worldwide, and are
generally associated with the coral reefs upon which they feed. Parrotfish have a specific …

The molluscan feeding structure is the radula, a chitinous membrane with teeth, which are
highly adapted to the food and the substrate to which the food is attached. In Polyplacophora …

The gastric mill of Decapoda is a unique feature, which comprises teeth, stabilizing ossicles,
and particle sorting setae. Involved in the fragmentation and sorting of the food, this structure …

Abstract The potentially molluscivorous East‐African cichlid Astatoreochromis alluaudi is
known to exhibit phenotypic plasticity in its pharyngeal jaw apparatus. We examined wild …

This study investigated the ecomorphology of pharyngeal jaw structure and durophagy in
three families of marine teleosts: the Sciaenidae, Haemulidae and Carangidae. Regressions …

Perhaps the most striking feature of billfishes is the extreme elongation of the premaxillary
bones forming their rostra. Surprisingly, the exact role of this structure in feeding is still …
