Abstract: Swimming animals commonly bend their bodies to generate thrust. For undulating animals such as eels and lampreys, their bodies bend in the form of waves that travel from head to tail. These kinematics accelerate the flow of adjacent fluids, which alters the pressure field in a manner that generates thrust. We used a comparative approach to evaluate the cause-and-effect relationships in this process by quantifying the hydrodynamic effects of body kinematics at the body-fluid interface of the lamprey, Petromyzon… Show more

“…To increase the sensitivity of our swimming assay, we used ANY-maze software (Stoelting) to quantify kinematic parameters including maximum speed, total distance traveled, and latency to immobility. Notably, our observation of the maximum swimming speed of approximately three body lengths seconds −1 in uninjured lampreys was consistent with previous reports (Gemmell et al, 2016). As with the semiquantitative assessment, deficits were clearly observed immediately following TX but improved over the following weeks.…”

“…Excluding the cells within an interrogation window that contain a body may be accomplished by dynamic masking. Dynamic masks may be isolated with image processing from a single-channel recording when the body is uniformly illuminated (Gemmell et al, 2016), but the lighting conditions that are amenable to recording particles are generally unfavorable for visualizing the body. As a consequence, the body is often manually drawn for each frame of the video (Gemmell et al, 2016;Tytell and Lauder, 2004), which is labor-intensive.…”

As a consequence, the body is often manually drawn for each frame of the video (Gemmell et al, 2016;Tytell and Lauder, 2004), which is labor-intensive. As demonstrated presently, MSV provides the opportunity to resolve this challenge by producing images of the moving body under transmitted illumination that may be easily converted into a dynamic binary mask.…”

“…7) (17,25,27). Even among anguilliform swimmers, the larval lampreys studied by Gemmell et al (25,26) have particularly large anterior body movements (28). These undulations rotate the body surface, which accelerate the adjacent fluid, strengthen the fluid's vorticity, and generate large regions of negative pressure (Fig.…”

“…Specifically, Gemmell et al (25,26) quantified the pressure distribution around larval lampreys and found that they produce negative pressures along the anterior parts of their bodies, resulting in thrust forces. In essence, larval lampreys suck themselves forward.…”
