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
The oceans cover 71% of the planet and pose a myriad of hazards to everyone from blue-water sailors to the casual beachcomber. From rip currents to rogue waves, the possibilities for some water-borne calamity seem endless, but in most cases a deadly outcome can be avoided or at least mitigated by having a better understanding of the risks involved. This book presents cautionary tales of the most dangerous aspects of oceans encounters, including hazardous sea life such as sharks and rays, the power of waves and high seas that can engulf an entire fleet of naval vessels. In each case the author provides actual examples of various ocean phenomena and the people who either survive or succumb to them, from competitive big-wave surfers to the passengers and crew of the ocean liner Queen Elizabeth 2, severely damaged by a 95-foot wave that seemed to come out of nowhere in the middle of the night. The author also addresses several well-known maritime disasters and their causes, as well as such phenomena as the so-called Bermuda Triangle. Above all, The Ominous Oceans seeks t provide a better understanding of the perilous seas, so that we will be better prepared before taking that swim or venturing off to places unknown.

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.

Book Description
Chondrichthyes are a group of cartilaginous fish, where we have sharks, rays, and chimeras as members. This group plays an important role in aquatic ecology, as they act as predators throughout the food chain (e.g., sharks). However, many populations of Chondrichthyes are threatened by several factors (increased direct fishing, high mortality rate as accompanying fauna, marine pollution, habitat destruction, etc.). These declines are evident in many parts of the world and have come to the attention of scientists, conservation organizations, the media, and the general public. Fisheries legislation regulating international fisheries markets has been amended to provide greater protection for this group along with other species of fish. However, little is known about these species, which reinforces the importance of studies in order to have a better understanding of the elasmobranch stocks, as well as to identify the influences of the anthropic action of fishing. In response to knowledge on the low sustainability of cartilaginous fish fisheries on a global scale, FAO has developed an international plan of action for the management and conservation of these fish, with the aim of developing and implementing national plans of action to ensure management and conservation of these stocks, having as main recommendation the collection of information about the Chondrichthyes, especially the sharks. Even so, this group is little known in terms of biodiversity, ecology, behavior, and a host of other characteristics relevant to this taxon, which is very worrying. Chondrichthyes - Multidisciplinary Approach attempts to portray to the readers up-to-date information on Chondrichthyes to promote an overview of the current taxon, serving as an indispensable source of access to more accurate and detailed information on shark rays and chimeras.

Book Description
Inspired by the International White Shark Symposium in 2010, Global Perspectives on the Biology and Life History of the White Shark incorporates the most important contemporary research findings into a single peer-reviewed book. This beautifully illustrated reference represents a historic change in the context of White Shark (Carcharodon carcharias) research. Once considered one of the most poorly understood and difficult sharks to study, this timely book recognizes a new sophisticated focus on the White Shark, raising its status from obscurity to enlightenment. The Global Perspectives on the Biology and Life History of the White Shark celebrates the White Shark as the most studied shark in the sea. Within the chapters one can find new insights into a vast range of topics, such as behavior, physiology, migration patterns, habitat preferences, daily activity patterns, molecular genetics, reproductive biology and new research methods. The book also delves into population monitoring and policy options for managers and researchers.

Book Description
Sharks and their relatives, the rays and chimaeras, are the diverse group of cartilaginous fishes that have evolved over 400 million years. Historically considered of low economic value to large-scale fisheries, today many of these fishes have become the target of directed commercial and recreational fisheries around the world, and they are increasingly taken in the by-catch of fisheries targeting other species. This report emphasizes the widely-acknowledged need to improve shark fishery monitoring, expand biological research and take management action. It serves as an introduction to the ecology, status and conservation of the sharks and their relatives for a general audience. Shark fisheries can only be managed sustainably, and shark populations remain viable, with the introduction of new conservation and management initiatives.
