Marine animal stings or bites refer to venomous or poisonous bites or stings from any form of sea life, including jellyfish.
Almost 2000 species of animals found in the ocean are either venomous or poisonous to humans, and many can produce severe illness or death. An estimated 40,000 to 50,000 bites or stings from marine creatures occur each year. In recent years, the number of injuries caused by these animals has increased dramatically because of the greater number of people who take part in scuba diving, snorkeling, surfing and water sports. These animals are not usually aggressive, and many are stuck to the ocean floor. Most venomous or poisonous marine animals in the United States are found along the California, Gulf of Mexico, and southern Atlantic coasts.
Stings - marine animals; Bites - marine animals
The majority of these types of bites or stings occur in salt water. Some types of marine stings or bites can be deadly.
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.
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:
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.
