There have been notable studies comparing the eye placement between predators and prey, which can be further categorized as omnivore, carnivore, and herbivore. The purpose of this study was to determine if eye placement correlated with extrinsic eye muscle differences among the classification of animals (predator vs. prey and omnivore vs. carnivore vs. herbivore). For an omnivore, a human orbit was dissected. A cat was dissected to represent a carnivore and a goat was dissected to represent an herbivore. Dissection protocol for the cat and goat were created due to the lack of dissections of these muscles. Unfortunately, data collection was incomplete due to the social distancing policy on Iowa State University’s campus because of COVID-19. Even though the data was incomplete, dissection techniques, dissection of different tissue types, and next steps were learned. This case study should be continued, and a concrete protocol for extrinsic eye muscle dissection should be created for lateral eyed mammals.
