Marine animal stings or bites

Marine animal stings or bites refer to poisonous bites or stings from any form of sea life, including jellyfish.

Considerations

The majority of these types of stings occur in salt water. Some types of marine stings or bites can be deadly.

Causes

Causes include bites or stings from various types of marine life including: jellyfish, Portuguese Man-of-War, stingray, stonefish, scorpion fish, catfish, sea urchins, sea anemone, hydroid, coral, cone shell, sharks, barracudas, and moray or electric eels.

Symptoms

There may be pain, burning, swelling, redness, or bleeding near the area of the bite or sting. Other symptoms can affect the entire body, and may include:

  • Cramps
  • Diarrhea
  • Difficulty breathing
  • Groin pain, armpit pain
  • Fever
  • Nausea or vomiting
  • Paralysis
  • Sweating
  • Weakness, faintness, dizziness

First Aid

  • Wear gloves, if possible when removing stingers.
  • Wipe off stingers or tentacles with a towel.
  • Wash the area with salt water.
  • Soak the wound in as hot of water as the patient can tolerate for 30 - 90 minutes, if told to do so by trained personnel.
  • For some types of stings/bites, you may be told to apply vinegar or a meat tenderizer/water solution to neutralize the venom.

DO NOT

  • Do NOT attempt to remove stingers without protecting your own hands.
  • Do NOT raise the affected body part above the level of the heart.
  • Do NOT allow the patient to exercise.
  • Do NOT give any medication, unless told to do so by a health care provider.

When to Contact a Medical Professional

Seek medical help (call 911 or your local emergency number) if the person has difficulty breathing, chest pain, nausea, vomiting or uncontrolled bleeding, if the sting site develops swelling or discoloration, or for other body-wide (generalized) symptoms.

Prevention

  • Swim near a lifeguard.
  • Observe posted signs that may warn of danger from jellyfish or other hazardous marine life.
  • Do not touch unfamiliar marine life. Even dead animals or severed tentacles may contain poisonous venom.
