Among fishes there are obvious species differences in number of gill arches, as well as in number and length of gill filaments. Less obvious are species differences in number and size of the respiratory units, the gill lamellae. This suggests that there is also variation in gill surface area per unit of size of fish. Since fishes occupy a variety of ecological niches it is of interest to know if the gill area may in any way be correlated with activity and habitat.Although there have been many studies on the anatomy of fish gills, only a few investigators have concerned themselves with gill area. Riess (1881) was among the first to attempt accurate measurements of gill surface. He found that pike had 125 sq. mm. of respiratory surface per gram of body weight. Putter (1909) de-Gray, I E. 1954.

The benthic macroinvertebrate fauna of the continental shelf off North Carolina may be divided into three species assemblages, each occupying a given area and corresponding to three biogeographic provinces. North of Cape Hatteras, in a wedge having its narrow end near Diamond Shoals, the fauna and the environment correspond to the Virginian Province. South of Cape Hatteras, over roughly the inshore half of the continental shelf, the Carolinian Province is represented. Offshore from these two provinces, over the outer half of the shelf, lies the Tropical Province. Conclusions regarding these faunas and these provinces are based on dredging collections including 211 species representing 16 classes from 6 phyla. One-fourth of the total number of species are new distribution records for the coast of North Carolina.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
