Territorial analysis of Atlantic Sharpnose Pufferfish (Canthigaster rostrata)

Marissa NeitzkeAbstract: Very little is known about Canthigaster rostrata (Sharpnose Pufferfish). It has already been determined that the C. rostrata are a dimorphic species that tend to stay within territorial habitats. My scale of interest was looking at how C. rostrata interact amongst one another. I was curious to know whether or not males or females were more aggressive, and if so, why? To learn more, a research plan was created to grasp more information about the territorial behavior of C. rostrata. Observing on a weekly basis for a month, we determined the sex, size and action of each individual we came into contact with.
