Nanoindentation, laser ablation inductively coupled plasma mass spectroscopy and
weighing ion-spiked organic matrix standards revealed structure-property relations in the …

The jaws of the marine worm Nereis sp. are made of protein fibers and are reinforced by
zinc. Here we study a transverse section through the jaw using optical microscopy and …

Jaws have evolved numerous times in the animal kingdom and they display a wide variety of
structural, compositional, and functional characteristics that reflect their polyphyletic origins …

Onychophorans are carnivorous, terrestrial invertebrates that occur in tropical and temperate
forests of the Southern Hemisphere and around the Equator. Together with tardigrades …

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 …

Higher animals typically rely on calcification to harden certain tissues such as bones and
teeth. Some notable exceptions can be found in invertebrates: The fangs, teeth, and …

The arthropod cuticle is a remarkable and versatile biological material commonly composed
of chitin and proteins. Lessons can be learned from the way it is adapted to fit its functions …

In contrast to vertebrate teeth that are commonly hardened by calcium‐based biominerals,
invertebrates rely on more diverse strategies including the incorporation of large quantities …

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 …

A combination of position-resolved synchrotron microbeam techniques was used to explore
the distribution and role of trace transition metals in the jaws of Glycera dibranchiata. The …
