Comparative morphology of cheliceral muscles using high‐resolution X‐ray microcomputed‐tomography in palpimanoid spiders
Spiders are important predators in terrestrial ecosystems, yet we know very little about their principal feeding structures—the chelicerae—an extremely important aspect of spider biology. Here, using micro‐Computed‐Tomography scanning techniques, researchers perform a comparative study to examine cheliceral muscle morphology in six different spider specimens. Read more »

The Microstructure of a Parrotfish Tooth Contributes to Its Toughness
Parrotfish chew on coral, producing hundreds of pounds of sand each year. Mapping the microstructure of parrotfish teeth, scientists found bundles of crystals interwoven like chain mail. The results provide a blueprint for creating ultra-durable materials for mechanical components that undergo repetitive contact, movement, and abrasion. Read more »
X-Rays Reveal the Biting Truth About Parrotfish Teeth
A parrotfish’s hardy teeth allow it to chomp on coral all day long, ultimately grinding it up through digestion into fine sand. Researchers wanting to see how the fine crystal structure of parrotfish teeth contribute to their incredible strength were able to visualize the orientation of individual crystals, which showed their intricately woven structure.
