We used a Kruskall-Wallis test and a Boxplot graphic to compare species; and a PCA test to identify body variables that influence swimming. A Non-Metric Dimensional Scaling (NMDS) test was done for species and position in the water column. <strong>Results:</strong> The fastest swimming corresponded to <em>A. nigrofasciata</em> (9,29cm/s), while <em>S. salvini</em> (1,65cm/s) was the slowest. Burst swimming speed is influenced by body size and tail type, and differed with position in the water column, being surface species the fastest. <strong>Conclusions:</strong> Morphological and ecological characteristics determine differences in burst swim.</p>}, number={3}, journal={UNED Research Journal}, author={Quesada-Alvarado, Francisco and Campos-Calderón, Fernando}, year={2019}, month={Dec.}, pages={395–402} }
