Abstract

AbstractCover illustration. The shortfin mako Isurus oxyrinchus is perhaps the fastest swimming shark. The modified scales on the lateral flank of the shark are highly flexible and are believed to erect during rapid swimming. Erection of the flank scales and resulting drag reduction is hypothesized to be passively driven by localized flow patterns over the skin.
