26. What can I do to minimize my risk of shark attack?
The risk is already extremely small. The average American has a 1 in 5 chance of dying from heart disease, a 1 in 7 chance of dying from cancer, and a 1 in 3.8 million chance of being killed by a shark. However, there are a few basic common-sense strategies that swimmers and surfers can use to further reduce their chances of being bitten by a shark. Try to remain relatively close to shore and to other people. Try to swim during the day and not around dawn or dusk when sharks tend to be most actively hunting. Try to avoid areas near river mouths, as water there tends to be murky and some sharks like to hang out there, hoping a free meal will wash out to sea. Do not swim or dive in areas of unusually high fish density where sharks are likely to be feeding. Remember, you want to make it as easy as possible for a shark to identify what you are: a human being, not something they consider food. These are some suggestions gleaned from our years of knowledge, but SRC is not responsible for your safety. You are at your own risk when entering in the ocean.

27. Why do sharks bite people?
We don’t really know, but humans aren’t a primary food source for sharks. One of the leading theories is that most shark bites are a case of mistaken identity. It has been suggested that the outline of a surfboard being paddled by neoprene-wearing surfers looks an awful lot like a seal from below or the palm of a human hand or the sole of a human foot can easily be mistaken for the white belly of a distressed fish. The evidence suggests that most shark bites are accidents, where the shark mistakes a human (or part of a human) for something else. Some bites also occur when human swimmers or surfers accidentally step on a small shark resting on the bottom.
Many species of sharks are curious animals. When they come across something unusual, they want to learn more about it. If you or I wanted to know what something was, we’d pick it up and look at it more closely. Because sharks have no hands, they primarily use their mouth to investigate things they are curious about. When they mouth a human out of curiosity, we still perceive it as an “attack”—although in most cases it would be more accurate to describe it as an “accidental” or “experimental” bite.

28. Why do people eat shark fin soup? What is shark finning?
Shark fin soup is a traditional delicacy in Chinese culture dating back centuries. It was first consumed in Ming Dynasty China (1368-1644), by members of the Imperial court. As living standards in China have improved over the last few decades, shark fin soup has become increasingly accessible to the middle class. It is usually served at special, formal occasions like weddings, banquets and important business functions. Serving shark fin soup is considered to be good luck, but is also an important way to express respect for your guests and to honor them. It is also eaten as a cultural sign of wealth.
Shark fin soup itself has no color, taste, or smell and requires addition of chicken, beef, or pork broth to add flavor. However, the cartilage from the shark fin provides texture to the soup.
Tens of millions of sharks are killed annually for their fins and are being fished out faster than they can reproduce which is leading to several shark populations declines globally (See FAQ #14 & #15).
In recent years, many people in China and people of Chinese descent around the globe have become increasingly aware of the ecological problems associated with shark fin soup, and have begun arguing that it should no longer be consumed. Recently, the Chinese government announced it will no longer serve shark fin soup at governmental events.
Although shark fins are primarily consumed in Asia, shark finning (and fishing for their fins), is a global phenomenon. According to a recent report, 83 countries or territories supplied more than 10.3 million kilograms (22.7 million pounds) of shark fin products to Hong Kong in 2011. The top countries exporting fins to China include Spain, Mexico, and the U.S. More details can be found by clicking HERE.
Shark finning is the act whereby sharks are caught at sea, their fins are removed and kept, while the rest of the shark’s body is discarded at sea. Shark finning occurs mostly because shark meat is rarely consumed. In contrast, trading in shark fins is extremely lucrative. A single bowl of soup can cost hundreds of dollars. In several countries, including the United States, the act of shark finning is illegal, whereby the shark body is not discarded at sea. Instead, the whole body must be brought to shore before the fins are removed and sold.
29. Is consuming shark fins healthy or unhealthy?
A study recently completed by Hammerschlag and colleagues from the University of Miami revealed that shark fins contain high concentrations of a neurotoxin called BMAA, short for β-N-methylamino-L-alanine. BMAA has been linked to diseases such as Alzheimer’s, Parkinson’s and ALS. The study suggests that consumers of shark fins (and other parts) are at a risk of getting these neurological diseases. The study has generated tremendous scientific, media and public attention that will hopefully lower the demand for shark fins and also help protect people from diseases like Alzheimer’s, Parkinson’s and ALS.

30. Are sharks worth more alive than dead?
In 2009, Palau declared their waters a “shark sanctuary” making it illegal to harvest sharks. They took this action not only because they recognized that sharks are ecologically critical to marine health, but because it made practical economic sense. It has been estimated that one individual living reef shark in Palau can generate up to $1.9 million in eco-tourism dollars over her lifetime, compared to a value of approximately $108 if she were killed for her fins (Vianna 2010). Moreover, in countries which rely on dive and marine-based tourism, the contribution sharks make to healthy marine ecosystems is important to the tourism industry. A study by SRC team members, Dr. Hammerschlag and Dr. Austin Gallagher, conducted a global analysis of all shark diving ecotourism and showed that the growing tourism industry can potentially generate more money over time for local economies than directly harvesting sharks for sale (Gallagher & Hammerschlag 2011). This and other similar economic analyses have helped prompt the creation of numerous shark sanctuaries and laws intended to help protect fragile shark populations. Here are a few the recent legal successes for sharks:
- September 2009 — Palau created the first national shark sanctuary. No fishing of sharks is permitted within the national waters of Palau.
- December 2010 — The United States passed the Shark Conservation Act, banning shark finning in US waters. This law means that shark fins cannot be brought to dock in the United States without the bodies of the sharks, dramatically limiting the number of shark fins a vessel can collect on each voyage.
- June 2011 — Honduras created a shark sanctuary protecting sharks along both their Pacific and Caribbean coasts.
- July 2011 — The Bahamas banned all commercial shark fishing within Bahamian national waters.
31. Does shark diving or chumming cause shark attack or negatively impact shark behavior?
While some concerns have been raised that shark feeding dives might cause sharks to associate humans with food, there is no scientific evidence that shark eco-tourism increases risk of shark attack. Research is ongoing into how to prevent ecotourism from disrupting natural shark behaviors, and protect sharks from behavioral changes that might put them at risk. Responsible and well-regulated shark ecotourism operators can play an important role in educating people about sharks and promoting shark conservation. A recent study, conducted by the SRC team, did not find that dive ecotourism effected the long term movements of tiger sharks in the Bahamas. Click HERE to learn more.
32. Does your research hurt the sharks?
Every aspect of our data gathering process is designed to minimize harm to our research subjects. We use special fishing and tagging gear intended to reduce stress, shorten handling time and promote shark safety. Please explore our Animal Welfare section of the website to learn more about the special protocols our team follows to promote shark welfare.
The Shark Research & Conservation Program uses special fishing units called drumlines (composed of a single weight and attached hook & line) that promotes shark vitality when fishing for sharks. The gear permits species which are ram ventilaters (need to keep moving to breathe) to swim in big circles around the weight when caught. The ability to swim relatively freely also minimizes stress-related C02 and lactic acid buildup in shark muscle. This gear promotes shark survival.
Circle hooks can help reduce negative outcomes for captured sharks over other commonly used hooks, most notably J hooks. Circle hooks are designed to catch in the shark’s jaw, instead of catching on the shark’s stomach or gills, which can otherwise cause serious injury. The hooks can also easily be removed from the jaw and leave a very superficial wound that heals very quickly. Circle hooks also help us selectively target sharks, reducing unwanted bycatch of other species. We recommend circle hooks not only for research-related capture, but for recreational fishermen practicing catch and release fishing who want to increase the likelihood of release their catches in good condition.
When a caught shark is brought onto a specialized, partly-submerged, platform on the back of our research vessel, a saltwater pump is immediately placed in the sharks’ mouth. This allows highly oxygenated water to flow over its gills throughout the shark’s brief ”check-up.” During this workup, sharks have a small muscle biopsy taken (recaptured sharks demonstrate that the biopsy site is completely healed within just a few weeks), are tagged with a spaghetti tag in their dorsal fin (where they have no nerve endings and no blood vessels), have blood drawn, are measured, have a small clip of their fin cartilage taken, and are released.
The traditional method for getting the type of data we collect was to kill the animals. Although capture may still be a relatively stressful process for sharks, our work focuses on minimizing shark stress to the greatest extent possible and promoting shark vitality and survival.
Our work has been proved successful with minimal shark stress. Our methods have been approved by the University Animal Welfare & Care Committee. It is also worth noting, that based on all available scientific evidence available, it appears that sharks do not feel pain.
33. Do sharks feel pain while you work them up?
Sharks have significantly fewer nerve endings than humans do. Humans have developed tremendously complex nervous systems with many millions of nerves as part of the process of evolution, these nerves “teach” us—through pain—what we should and shouldn’t do (don’t touch a hot stove). However, this level of sensitivity to temperature, pressure or pain has not been necessary for sharks. The nerves that report tissue damage and lead us to feel “pain” are neurons called “nociceptors” which account for approximately 50 percent of all human neurons, but only 13 to 38 percent of shark neurons and less than 1 percent of ray neurons. Sharks have many fewer nerves than we do, and devote a smaller percentage of those they do have to feeling pain. Therefore, although we don’t know exactly how it feels to a shark when we tag it, we can say for certain that they have neither the nerve endings nor the neurological apparatus to experience pain the way a human would.

34. Do your tags cause fin damage?
All tags are not permanent. They fall off over time and the application point heals back quickly. Some of our satellite tags are temporarily attached to the shark’s dorsal fin. However, sharks have no blood or nerve supply to their fins. We’ve also recaptured satellite tagged sharks after months at liberty, and their fins appeared undamaged. The potential effects on the sharks are minimal considering the research and education it provides, which will help protect these threatened species. For more information, please read our paper on satellite tags, which further discuss the potential for negative impacts on sharks (right).
35. Why does a shark transmission stop?
Satellite tags are essentially fancy computers attached to live sharks. There are a number of things that can happen to a tag once it is released.
- In order for a tag to transmit the shark must break the surface of the water. This can sometimes be infrequent and sporadic.
- Our tags are equipped with enough battery life to sustain up to a year of transmissions. However, this number is variable depending on the frequency a shark transmits. More transmissions will cause a tag to lose battery quicker.
- Satellite tags are designed to eventually pop of a shark so the animal is not swimming with it indefinitely. The tags are attached using titanium that will corrode in saltwater; the length of the corrosion process varies with conditions in the water such as salinity and temperature.
- As a shark heals the tag can actually get pushed right out of the fin.
- As the tag travels with a shark it can accumulate algae and other organisms. This can block the tag and prevent it from successfully transmitting.
- As sharks go through life there is potential for collision. For example, run-ins with other sharks or getting caught in a coral reef can break the tag and prevent transmission.
36. Can satellite tags interfere with shark electromagnetic senses?
There is no scientific evidence that satellite tags interfere with shark senses. Based on data from our satellite tags, it appears that tagged sharks are able to swim, hunt, migrate and participate normally in all natural shark behaviors. We would expect a much higher level of morbidity and mortality among tagged sharks if the satellite tags interfered with their sensory systems. For further discussion, click HERE.
37. Does posting shark tracks online help fishermen find and exploit sharks?
No. Although this is a concern raised by shark conservation advocates, the reality is that fishing is everywhere. Except where they are already protected and properly managed, there is no place where sharks are safe from fishing. The fishing industry is way ahead of scientists in terms of knowing where the sharks are. Sometimes, the fishing industry even hires oceanographic data analysts to identify potential fishing “hot spots” in real time, reporting these locations to fishers at sea. It is scientists that are playing catch up and the tracking data generated is used to help managers make informed conservation decisions. To us, the tracking data not only helps conservation management, but the educational benefits of free, interactive online shark tracks we post helps generate public awareness and support for shark conservation.
38. What can scientists learn from satellite tagging sharks?
Satellite tags allow scientists to study the migratory routes and residency patterns of sharks. This data can be used to identify areas that are critical for shark mating, giving birth and feeding as well as locations where sharks are vulnerable to destructive fishing. These data can help policy makers implement effective management strategies that will improve conservation for threatened shark species.
