Sea snake bites can occur by accident either by stepping on it or when fishermen remove them from fishing nets. It is important to note that sea snakes are not typically aggressive unless provoked. Even though they are highly poisonous, only some cases of bites can cause significant symptoms.

During sea snake bites, the venom is injected by its fangs. Most have fangs that are elongated enough to pierce a wetsuit. Remember that the venom is highly toxic and potent.

What are the signs of sea snake bites?

It is important to note that a bite from a sea snake does not trigger pain right away.

  • The bite site might only display a small-sized pin prick without any pain.
  • The site of the bite rarely shows any reaction. An individual bitten by a sea snake does not show any signs of bruising, redness or other indications at the site of the bite, even if the venom was introduced.

  • An elastic bandage must be wrapped around the affected extremity starting at the distal point and towards the body. Make sure that it is secure but does not disrupt with normal circulation.
  • The affected extremity must be immobilized with a splint¬†to prevent it from bending at the joints.
