... of the lubricated skin in the field virtually impossible. However, modeling the swordfish features in fast water tunnels could test our hypothesis and offer new perspectives for biomimetics studies aimed at drag reduction. The swordfish oil-gland system, with its capillary vessels, pores in the skin...

.... But no studies to date have tested these claims of drag reduction under dynamic and controlled conditions in which the swimming speed and hydrodynamics of shark skin and skin-like materials can be quantitatively compared with those of controls lacking surface ornamentation or with surfaces in different...
