This series of fish scales shows the many variations in morphology between fish species. The splitfin flashlight fish has highly ornamented scales with many spines on their surface. This image also shows roughness on the surface of the tail, as well as the higher-height lateral line canal that runs down the body. For this dataset, … Read more
This series of fish scales shows the many variations in morphology between fish species. The Ozark Bass is a native North American fish that has large ctenoid scales, which have very tiny spines on the edge pointed towards the tail. These small spines are typical of many species of fishes. For this dataset, a 4th … Read more
This series of fish scales shows the many variations in morphology between fish species. The Dusky Smooth-Hound is a shark, meaning it has tiny scales (called placoid scales or denticles). These features have complex, 3D shapes and create a surface made of their crowns which protrude above the skin. The crowns often have posterior points … Read more
This series of fish scales shows the many variations in morphology between fish species. The Black Nox Angelfish is a tropical coral reef fish that has large scales with very long spines that point posteriorly, giving the surface a ridged appearance. This fish even has these scales on parts of their fins, such as the … Read more
This series of fish scales shows the many variations in morphology between fish species. The American Shad is native to North America and migrates from salt to freshwater to breed in the spring. This species has large crenate scales, where the scale extends into weak protrusions (not quite spines) along its posterior edge. For this … Read more
This dataset is featured in our article, Analyzing additive surfaces with directional filtering. The small particles of partially-melted power are challenging to quantify. The striped pattern created by the additive manufacturing process makes the particles difficult to isolate. Directional filters—a standard feature of OmniSurf3D software—make it possible to suppress the ridges while retaining the features … Read more
