Each year, there are about 100 reported shark bites all over the world. Of these 100, only 10 to 15 are considered serious and life-threatening. It is a known reality that humans cause more harm to sharks rather than the other way around. Most cases of shark bites are due to mistaken identity, wherein the sharks mistake humans for their prey, such as sea lions and seals. It is also known that some shark bites are due to provocation.
Sharks are one of the most feared animals in the world, which is primarily due to famous Hollywood movies, where sharks attack humans. In actuality, of the hundreds of identified shark species all over the world, there are only a few dozens that are particularly considered dangerous. The shark species most commonly involved in shark bites are the great white shark, tiger shark and bull shark.
Types of Shark Bite Attacks
There are three types of shark bite attacks: hit-and-run, bump-and-bite and sneak attack. Although the latter two are less common than the first, they are considered to be more serious and more lethal.
- Hit-and-Run Shark Bite Attack
- Most common
- Shark takes a single bite and leaves the victim after
- Bump-and-Bite Shark Bite Attack
- Shark head butts the casualty a few times before going back to take a few bites
- Sneak Attack Shark Bite Attack
- Shark bites without warning to the casualty and follows-up with further attacks
Signs and Symptoms of Shark Bites
In most cases of shark bites, the casualties are not aware that a shark is nearby. The only warning can be in the form of the shark’s fin approaching or sometimes, the bump (heat butt) before the attack. The following signs and symptoms are common of shark bites:
- Crescent–shaped shark bites
- In less serious cases, only an abrasion may appear due to the friction of the skin against the tooth of the shark (slightly superficial cuts)
- Parallel cuts
- In more serious cases, amputation of a whole body part
Fortunately, most puncture wounds caused by shark bites do not harm the blood vessels or cause injuries to the nerves.
First Aid Management of Shark Bites
Although some shark bites may not seem serious, it is still necessary t seek medical treatment immediately. Moreover, it is important to apply first aid as soon as the casualty is out of the water. Keep the casualty calm and reassure him/her at all times.
- Control the bleeding by applying deep pressure on the wounds. Use any clean, absorbent cloth. If the cloth is already soaked in blood, place a new absorbent cloth on top of the old one.
- Once the bleeding is controlled, wash the wound with soap and warm water.
- Apply an antiseptic and a sterile dressing to help avoid infection.
- If there is heavy bleeding, cover the victim with a towel or blanket to avoid loss of body heat. This is done to avoid hypothermia and shock.
- Check the casualty for circulation, airway and breathing. Initiate CPR if necessary.
- If there is an amputated limb, wrap the amputated part in sterile bandages and place inside a plastic before placing it in another plastic with ice.
