The denticles from the lateral flank of a leopard shark (Triakis semifasciata) were imaged and you can see the topographic reconstruction above. Denticles have been shown to increase swimming performance and understanding their surface topography is crucial for connecting the form of shark denticles to hydrodynamic function (see ‘The hydrodynamic function of shark skin and two biomimetic applications’ by Oeffner and Lauder, for example).
