Kinematic input and power requirement of the three models.
The velocity of three movements are used as input in the models: lower jaw depression (a), head elevation (b) and hyoid depression (c). In-vivo kinematics of three aquatic feeding acts are shown (black curves) alongside the kinematic input of the models (coloured curves). Each kinematic input variable is applied only to the relevant zones of the mesh, as shown in the coloured images at the top: a factor of 1 of the mapped colour scale (red) means that the equation for this kinematic variable is followed for 100%, a factor of 0 (blue) means that the mesh remains unaltered. Power requirements of the three models are shown in (d). The properties of models 1, 2 and 3 with their respective colour coding used in this article are shown in (e).
