Values of each variable are shown as a 2 × 2 matrix of body shape and swimming mode. Numbers in parentheses indicate the rank of the value, from one (lowest) to four (highest). Lowest values are shown in italics; highest in bold. Stact, actual Strouhal number; U*, swimming speed; URMS, root-mean-square fluctuation in steady swimming speed; CP,wake, wake power coefficient; CP,tot, total propulsive power; η, Froude propulsive efficiency; M, mackerel body shape; L, lamprey body shape; C, carangiform swimming mode; A, anguilliform swimming mode. Modified from Borazjani and Sotiropoulos (2010); note that the power coefficients are normalized differently.
