Shark attack-related injuries: Epidemiology and implications for plastic surgeons
Introduction
Sharks have both intrigued and terrified society for decades because of increased media attention and thrilling Hollywood drama. America's infatuation with sharks began following the release of the blockbuster movie Jaws 40 years ago. Since its debut, the film has had a broad cultural impact and has been criticized by many scientists for fueling negative stereotypes about sharks and their behavior toward humans.1 Worldwide, many conservationists have echoed the sentiment that the film has hindered efforts to convince the public that sharks should be protected, rather than feared and hunted. Fortunately, this perception has begun to shift over the past decade with subsequent interest in protecting these animals.
Recent studies have focused on quantifying shark populations in various locations, and several have demonstrated population growth for the first time in decades.2 Interestingly, the ocean surrounding Cape Cod, Massachusetts, has been identified as having one of the fastest-growing shark populations. Coincidentally, this portion of the state also represents a major referral area for our center.2, 3, 4 Due to a growing population of gray seals (Halichoerus grypus), it has been suggested that the Cape Cod area is home to a previously unrecognized breeding ground for some large species of sharks. These reports have frequently been sensationalized by local media, like other shark-related stories, as more sightings occur.4, 5, 6
As attacks occur infrequently, the impact of shark attacks does not typically merit the degree of apprehension they inspire. Nonetheless, when attacks occur, the victims present with significant tissue defects, requiring early intervention by reconstructive surgeons after initial resuscitation. This study aims to report the details of both fatal and nonfatal shark attacks in an effort to improve the treatment of shark-attack victims by plastic surgeons and highlight some of the reconstructive challenges inherent in the treatment of these patients.

Patients and methods
Using The Global Shark Accident File, maintained by the Shark Research Institute (Princeton, NJ, USA), investigation was conducted on the available data regarding shark attacks worldwide.7 This database represents a compilation of all known worldwide shark attacks dating back to the 1800s and contains approximately 6000 incidents. The database was queried for attacks occurring from 1900 through September 2014, with 5034 incidents being documented. All known forensic data associated with each
Results
Since the 1900s, a total of 5034 shark attacks on humans have been recorded. Of these incidents, 1205 (23.9%) were fatal and 3829 (76.1%) were nonfatal (Table 1). The victims were 80.4% male (4049) and 10.0% female (495); the gender was not reported for 9.8% of cases (490). The average age of all victims was 26.1 years (Table 1). Overall, since the 1900s, the number of shark attacks reported per decade has been on the rise (Figure 1). The relative number of fatal attacks has decreased. The
Discussion
Shark attacks have become a source of public interest in the latter half of the 20th century.8 Before the 1930s, sharks were not thought to pose any danger to humans.8 Sharks first came to the public's attention following attacks on navy crewmembers during World War II and spiraled into a media sensation following the release of the movie Jaws.1, 9 Since then, much effort has been made to catalogue data about shark attacks in an attempt to better understand them. To date, no database has more
Conclusion
The severity of the injuries sustained following shark attack is on a par with military injuries and high-speed motor vehicle accidents.8, 16, 20, 24 Advancements in medical care have led to improved outcomes for shark-attack victims. Plastic surgeons play a key role in the management of these patients; a heightened awareness of the circumstances of their attack and treatment of these victims may improve outcomes when this uncommon problem presents. Early resuscitation, appropriate antibiotics,

Sharing the waves: An exploration of surfer and shark interactions
2022, Marine PolicyCitation Excerpt :The most reportedly seen shark species was white shark, with 39 % of surfers reporting seeing a white shark (see Table 1). Previous research found that the shark species most commonly involved in shark attacks were white sharks, tiger sharks, bull sharks, gray nurse sharks, and mako sharks [20] all of which were commonly reported by surfers. Over half the sample (60 %) said that they are not afraid of sharks bothering them while they surf, with 15 % saying they were unsure, and 25 % stating they are afraid.

2021, Chinese Journal of Traumatology - English EditionCitation Excerpt :The media attention including shark movies led to the public perception of its fatal property.1 Some of shark attacks represent devastating injuries with a high morbidity and significant mortality; however, they are rare unique pathological processes, and the published articles are limited.2,3 The challenges during management of such injuries include exsanguination, shock, specific injury pattern and infection with multimicrobial flora, especially marine Vibrio species.
Shark Related Injuries: A Case Series of Emergency Department Patients
2018, American Journal of Emergency MedicineCitation Excerpt :Most lacerations were superficial and 80% occurred on the lower extremities [2]. A 2016 study of 5304 shark attacks from 1990 to 2014 categorized injuries as unspecified (23.4%), minor (4.6%), and no injuries (14.2%), with most also occurring on the legs (41.8%) [1]. The Shark-Induced Trauma Scale (SITS) was introduced by shark researchers to consider blood pressure, location and depth of injury, extremity or organ loss of function, treatment, and patient survival [2].
