Nature Communications, Published online: 29 April 2026; doi:10.1038/s41467-026-72415-7 Here, the authors identify ten morphogroups of dermal denticles across extant shark species and quantify their mechanical properties and material composition alongside swimming performance, linking these traits to distinct ecological niches.
