The researchers did not provide a definite sample size for the number of sharks used in the experiment, which could be useful for supporting that the data is reliable. As well, the passive swimming data was collected during the surgery recovery period, which could influence the shark’s performance during the trial. Instead, the researchers could have ran the trials after giving a period of rest to the sharks. Regarding the methods employed in collecting, hook and line fishing can cause injuries in the sharks, which could cause stress and become another variable to control. Other alternative methods of fishing such as employing nets could reduce the risk of injury and no longer suppose a stress factor once the shark has been released from the net. Finally, the specimens used in the experiment were probably juveniles, since they measured between 80 and 112 cm in total body length, but adults measure around 3.2 meters. Thus, the actual kinematic data for adult mako sharks will probably vary from the results obtained in the study.
