Book Description
A detailed account of over one hundred shark-related incidents on the coast of the Carolinas from a shark-bite investigator Powerful and mysterious, sharks inspire both fascination and fear. Worldwide, oceans are home to some five-hundred species, and of those, fifty-six are known to reside in or pass through the waters off the coast of both North and South Carolina. At any given time, waders, swimmers, and surfers enjoying these waters are frequently within just one-hundred feet of a shark. While it's unnerving to know that sharks often swim just below the surface in the shallows, W. Clay Creswell, a shark-bite investigator for the Shark Research Institute's Global Shark Attack File, explains that attacks on humans are extremely rare. In 2019 the International Shark Attack File confirmed sixty-four unprovoked attacks on humans, including three in North Carolina and one in South Carolina. While acknowledging that they pose real dangers to humans, Creswell believes the fear of sharks is greatly exaggerated. During his sixteen-year association with the Shark Research Institute, he has investigated more than one hundred shark-related incidents and has maintained a database of all shark–human encounters along the Carolina coastlines back to 1817. Creswell uses this data to expose the truth and history of this often-sensationalized topic. Beyond the statistics related to attacks in the Carolina waters, Sharks in the Shallows offers a history of shark–human interactions and an introduction to the world of shark attacks. Creswell details the conditions that increase a person's chances of an encounter, profiles the three species most often involved in attacks, and reveals the months and time of day with the highest probability of an encounter. With a better understanding of sharks' responses to their environment, and what motivates them to attack humans, he hopes people will develop a greater appreciation of the invaluable role sharks play in our marine environment.

Book Description
Knowledge of shark habitat preferences and use patterns is important to effectively manage shark fisheries and account for interactions between sharks and species targeted by other fishery management or conservation efforts. To gain baseline knowledge of the availability and spatial extent of shark habitat in North Carolina waters, habitat was assessed at three spatial scales: coastal nearshore, whole estuarine, and estuarine microhabitat. The local ecological knowledge of North Carolina fishermen was also incorporated and compared with data collected using fishery-independent means. Catch data and acoustic telemetry were used to assess shark habitat at the coastal nearshore scale. Sharks captured near Cape Hatteras could be grouped into warm water and cold water assemblages. Juvenile Dusky (Carcharhinus obscurus) and Sandbar (Carcharhinus plumbeus) Sharks were tracked using acoustic telemetry, and 12 of 15 tagged Sandbar Sharks were detected over an area from New York City to Savannah, Georgia. The spatial extent of potential juvenile Sandbar Shark habitat was influenced by a combination of sea surface temperature and chlorophyll-a concentrations, with habitat restricted to an area in the northern portion of Raleigh Bay near the Hatteras Bight during winter. At the estuarine scale, boosted regression tree modeling of shark catch and environmental data from North Carolina Division of Marine Fisheries (NCDMF) gillnet and longline surveys were used to spatially delineate potential habitat for six species within Pamlico Sound. Inlet distance and temperature were among the most influential environmental factors associated with species presence, while salinity was the most influential factor on abundance. Potential habitat for most species was located on the east side of the sound near the inlets with the exception of the Bull Shark (Carcharhinus leucas), which showed hot spots of potential habitat near sources of freshwater input. At the estuarine microhabitat scale, catch and environmental data from a fishery-independent survey conducted in Back and Core Sounds and a small-scale acoustic array deployed around Middle Marsh in Back Sound were used to identify associations between species and with specific habitat types. Spatial overlap between species was generally low and species assemblages separated based on water temperature. Smooth Dogfish (Mustelus canis), and Spiny Dogfish (Squalus acanthias) occurred primarily during mid-afternoon and Blacknose Sharks (Carcharhinus acronotus) occurring most often at night. A large Bull Shark tagged in another study accounting for the majority of tag detections and occurred within the array primarily during nighttime hours, most often on receivers deployed at two oyster reef sites and one sand flat site. Local ecological knowledge (LEK) of shark distributions and habitat preferences was gathered using structured interviews with North Carolina fishermen and their observations were compared with data from fishery-independent surveys and primary literature to assess their accuracy. All hypotheses generated from LEK were classified as either supported or plausible. Overall, water temperature was identified as an important influence on shark species presence and assemblage composition, with factors such as salinity and potential interspecific interactions more important at finer habitat scales. The locations and spatial extents of shark habitats in North Carolina are influenced by dynamic environmental factors and may be affected by large-scale perturbations such as climate change.

The reproduction and development of sharks, skates, rays and ratfishes

Book Description
This volume had its origin in a symposium on the Reproduction and Development of Cartilaginous Fishes that was held at the annual meetings of the American Elasmobranch Society and the American Society of Ichthyologists and Herpetologists in Charleston, South Carolina in 1990. The cartilaginous fishes, class Chondrichthyes, are a large and diverse group of fishes that include approximately 900 to 1100 living species of sharks, skates, rays and ratfishes. Throughout their history, which dates back at least 400 million years, they have been a successful major component of the marine ecosystem. The chondrichthyan fishes occupy a pivotal position in comparative and evolutionary studies of vertebrate reproduction and development. They are the oldest surviving group of jawed vertebrates and they possess both the adult vertebrate Bauplan and the vertebrate program of embryonic development. The major features of the female reproductive system, including its embryonic origin, structure, physiological function, and biochemistry, apparently were established early in vertebrate evolution and are fully developed in chondrichthyan fishes. These features of the female reproductive system have been retained during the evolution of the other classes of vertebrates. Much the same can be said for the male reproductive system. Moreover, viviparity, placental nourishment of developing embryos, and the hormonal regulation of these events made an initial appearance in this group. The 22 articles presented in this volume bring together a wide variety of complementary research by investigators from seven countries, allowing us to broaden the scope and implications of our studies while identifying opportunities for future research. The appearance of a volume on the reproduction and development of cartilaginous fishes is quite opportune. The continued existence of these fishes, which survived the great extinction events of Earth's history, is now threatened by overexploitation unless immediate steps for their conservation are undertaken. Knowledge of their reproduction and development not only is an end in itself, but is of critical importance in devising successful conservation and resource management strategies.
