Remoras pick where they stick on blue whales

By definition, the boundary thickness (δ) is turbulent boundary layer in some or most of the regions where the distance from the surface beyond which the flow becomes the structure of the vorticity and velocity profiles suggest that the irrotational; in good approximation, it was measured as the boundary layer remained transitional in our simulation (Figs 3 distance within which the flow velocity. [...] Still, one might expect that residing even partly find the pressure and friction forces on each facet of the surface of max in a boundary layer would lead to a benefit over swimming or the whale or remora from the computational grid and the coasting in the freestream as the full velocity profile faced seems components of those forces in the direction of swimming are always to carry with it at leas. [...] Instead, remoras were commonly momentum in the boundary layer to drag in the attached state observed to lift off the whale to feed and then return to their decreases in comparison to that of the flow over the section of the previous position (Movie 2), or other positions on the whale. [...] Therefore, though our absolute grid resolution of the simulated remora due to the large size of the drag values may be underestimates if the boundary layer flow is whale and therefore lower resolution of the computational grid at the indeed fully turbulent, remora seeking lower drag would still be scale of the remora. [...] 7A), the narrowing at the entrance to the space between 1.0 times hmax, 5.3 cm, a height representing the 90th percentile for the remora and the host surface results in an acceleration of fluid so the species of remora we observed.
