Raw data for manuscript: Feeding kinematics of a surgeonfish reveal novel functions and relationships to reef substrata

Feeding kinematics of a surgeonfish reveal novel functions and relationships to reef substratahttps://doi.org/10.5061/dryad.6t1g1jx59Datasets contain raw x and y coordinates of all bites analysed, and for each landmark throughout the sequences. Furthermore, the values used to compare kinematics from videos, to our biomechanical model, as well as the equivalent algal lengths (Figure 4) are also found here.Description of the data and file structureEach excel file (except for the ones containing comparative or algal length data) represents a single bite. ID is the unique name of each bite. X and Y are the raw x and y coordinates, whereas x_mm and y_mm are the scaled coordinates relative to the distance of the camera to the algae in each video sequence. Slice is the timesamp in ms that each landmark was placed in, when analysig in ImageJ. Time is the same Slice, except for t=0 is assigned as when the jaws of the fish begin to close. This was done to make all bites temporally comparable to each other.The 'rotations_raw' and 'morphology' files contain the data for Figures 4 and 5. In the 'rotations_raw' file Suction represents the pressence of suction in the bite sequences, Phase 2 shows whether there was a Phase 2 present in each sequence. Duration_total is the total duration of each bite in ms. jaw_open1_time is the duration in ms for the first jaw opening whne the fish approaches the algae to take a bite. Jaw_open2_time is the duration in ms of the second jaw oening, when the fish has detached the algae and re-opens its mouth to ingest the detached algae. Benthos_lj_min is the minimum distance the jaw reaches to the benthos (line defined by landmarks HG). Algae_l_mm is the length of the algae targeted for each sequence. Dist_L_stretch is the amount of motion by landmark L (i.e., cranial rotation) observed in the videos, dist_EI_stretch is the motion between landmarks E and I observed in the videos, and dist_IO_stretch is the motion between landmarks I and O observed in the videos. The next 3 columns are the same as the previous, but what was predicted from our model, when considering the anatomy of each specimen that performed the bites (see file 'morphology').For the 'morphology' file, the ID column is the independent ID of each specimen (see ID name of raw x,y coordinate files as well). SL is the Standard length of each specimen. All other columns represent distances (mm) between landmarks measured on the specimens upon dissections.Code/SoftwareThe 'A_leuc_analysis.R' file contains the code used to make the kinematic profiles (e.g., Figure 1-3).The 'rotations.R' file contains the code used to make the plots and analyses (i.e., statistical models) for Figures 4 and 5.
