    Shark Bite

    Shark Bite Symptoms

    Most people do not know a shark is nearby before an attack. Some people receive only a bump from the shark, which likely occurs when the shark is only investigating what is going on at the water's surface. Because a shark's skin contains tiny toothlike structures called denticles, it is as abrasive as coarse sandpaper. Thus, a bumping can result in a significant abrasion (scrape).

    Shark jaws contain multiple rows of sharp, serrated, triangular teeth, and are continuously replaced as they shed. Classic shark bites are crescent-shaped. Another common wound pattern is a series of parallel cuts caused by the shark raking its teeth on the person. Sharks bites can cause massive tissue loss, with a tooth-to-tooth biting force that has been estimated to approach, in the extreme, 18 tons per square inch. Most bites, however, result in cuts that are not deep, or puncture wounds that do not cause blood vessel or nerve injury.

    When to Seek Medical Care

    See a doctor for all shark bites. The doctor will evaluate the wound for significant damage, such as injury to blood vessels, nerves, or internal organs.

    Exams and Tests

    A person may not always know whether the wound came from a shark or another fish, such as a barracuda. Shark bites can cause significant bleeding and tissue loss.

    Bites are often crescent-shaped or appear as a series of parallel cuts. Encounters may result in minor wounds, such as abrasions from a shark bump. Some victims have bone fractures (breaks). Others may carry debris, such as shark teeth fragments, that may have been introduced into the wounds during the attack.

    Self-Care at Home

    Provide emergency care. Control any visible bleeding by applying direct pressure. Keep the victim calm. Provide warmth, since the victim may be chilled from the water and may be in shock.

    Call 911 to transport the person to an emergency medical facility. A doctor should evaluate all wounds.

    Thoroughly wash even minor wounds with soap and water. Cover wounds with clean gauze.
