A strong candidate is the mechanosensory lateral line, a hair cell-based sensory system that detects hydrodynamic information from sources such as water currents, predators, prey and surface waves. However, a role for the lateral line...

We collected data on such breaching behaviour for 14 fish and cetacean species primarily from online videos, to calculate breaching speed. From newly derived formulae based on the drag coefficient and hydrodynamic efficiency, we also...

.... Fish scale Streaks Hydrodynamics All bodies that move through a surrounding fluid will generate a boundary layer over their surface because of the no-slip condition at the boundary of the fluid region (‘the wall’) ( Schlichting and Gersten, 2017 ). This boundary layer is a region...

Here, we developed an experimental setup to measure the elastic properties of caudal fins in vivo by applying micro-Newton forces to obtain bending stiffness and a tensional modulus. We detected overall bending moments of 1.5×10 −9 –4×10 −9 N m 2 along...

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...

Sensitivity was assessed by modeling the mechanics and hydrodynamics of a flow stimulus. This model required that we...
