Bitten by the Sea: Coping with Wilderness Sea Snake Bites

April 23, 2023

Understanding Sea Snake Biology and Distribution

Sea snakes, also known as coral reef snakes or elastic-tailed snakes, are a group of venomous snakes that are found primarily in the waters surrounding Southeast Asia, Northern Australia, and the Pacific Islands. There are around 60 different species of sea snakes, with the most venomous being the beaked sea snake.

Biology

Sea snakes have several unique adaptations that allow them to thrive in marine environments. These include:

  • Fusiform body shape: This elongated, cylindrical shape allows sea snakes to move efficiently through the water.

  • Flattened tail: The flattened tail acts as a rudder, allowing sea snakes to make sharp turns and navigate through coral reefs.

  • Scaled skin: The scales on the skin of sea snakes are smooth and reduce drag, allowing them to move quickly through the water.

  • Salt glands: Sea snakes have specialized salt glands on the top of their heads that allow them to excrete excess salt, enabling them to drink seawater.

  • Valve-like nostrils: Sea snakes have valve-like nostrils that can close when the snake is underwater, preventing water from entering the lungs.

Distribution

Sea snakes are found in the tropical and subtropical waters surrounding Southeast Asia, Northern Australia, and the Pacific Islands. They are most commonly found in the shallow waters of coral reefs, but can also be found in mangrove swamps, estuaries, and along sandy beaches.

Recognizing and Treating Sea Snake Bite Symptoms

Sea snake bites are relatively rare, but can be life-threatening if not treated properly. It is important for individuals who may be at risk of sea snake bites, such as those who live in or visit areas where sea snakes are found, to be familiar with the signs and symptoms of a sea snake bite and know how to properly treat one.

Signs and Symptoms

The signs and symptoms of a sea snake bite can vary depending on the species of snake and the amount of venom injected, but may include:

  • Pain and swelling at the bite site.
  • Numbness or tingling around the mouth and extremities.
  • Weakness and muscle paralysis.
  • Blurred vision or double vision.
  • Difficulty breathing or swallowing.
  • Nausea and vomiting.
  • Sweating and drooling.
  • Heart rate changes.

It is important to note that some individuals may not experience any symptoms at all, or may have very mild symptoms, despite being bitten by a venomous sea snake.

Treatment

If you suspect that you or someone else has been bitten by a sea snake, it is important to seek immediate medical attention. The following treatments may be used to treat a sea snake bite:

  • Wound care: Clean the bite wound with soap and water and cover it with a sterile bandage.

  • Pain medication: Over-the-counter pain medication, such as ibuprofen, may be used to manage pain.

  • Antivenom: Sea snake antivenom is the most effective treatment for sea snake bites. It is important to administer the antivenom as soon as possible, as it can neutralize the venom and prevent serious complications.

  • Supportive care: Additional supportive care, such as oxygen therapy, may be necessary for individuals who are experiencing difficulty breathing or other serious symptoms.

If you suspect that you or someone else has been bitten by a sea snake, seek immediate medical attention and consider wound care, pain medication, antivenom and supportive care.

The Role of Antivenom in Sea Snake Bite Management

Antivenom is a crucial component in the treatment of sea snake bites. It works by neutralizing the venom and preventing serious complications from developing. There are several different types of sea snake antivenom available, each of which is specific to a certain group or species of sea snake.

How Antivenom Works

Antivenom works by binding to the venom and neutralizing its toxic effects. The antivenom is made from small amounts of venom that have been harvested from the snake, and then modified so that it no longer causes harm. The antivenom is then injected into the body, where it binds to the venom and neutralizes it.

Types of Sea Snake Antivenom

There are several different types of sea snake antivenom available, each of which is specific to a certain group or species of sea snake. Some of the most commonly used sea snake antivenoms include:

  • Polyvalent sea snake antivenom: This type of antivenom is made from the venom of several different species of sea snakes and is used to treat bites from multiple types of sea snakes.

  • Monovalent sea snake antivenom: This type of antivenom is made from the venom of a single species of sea snake and is used to treat bites from that specific species of snake.

It is important to note that the availability of antivenom may vary depending on location and region.

Administration of Antivenom

Antivenom should be administered as soon as possible after a sea snake bite. The dosage and number of vials of antivenom required will depend on the species of sea snake, the severity of the bite, and the individual’s response to the antivenom.

Side effects

Like any other medication, antivenom can cause side effects. They include:

  • Allergic reactions such as hives, itching, or difficulty breathing.
  • Nausea and vomiting.
  • Headache and dizziness.
  • Fever and chills.

It’s important to consult with a medical professional if you experience any of these side effects after receiving antivenom.
