coral snake

overview

coral snakes are found in tropical regions of north america and are often confused with non-poisonous (non-venomous) milk snakes because they look similar.

a coral snake can be up to 1 m (3 ft) long and has:

  • red, yellow, and black bands along the length of the body.
  • round pupils and a black nose.
  • fangs. coral snakes tend to chew on their victims for a few seconds and may leave tooth marks with or without fang marks.

at first, mild pain may be the only symptom of a coral snake bite. within 90 minutes, a feeling of weakness or numbness may occur in the bitten extremity.

other symptoms may appear up to 12 to 24 hours after a bite. symptoms may include:

  • increased salivation and drooling.
  • drowsiness or euphoria.
  • slurred speech.
  • nausea and vomiting.
  • numbness and tingling (paresthesia).

symptoms that occur less often include double vision, trouble breathing, sweating, muscle aches, and confusion. in rare cases, a person may die from a coral snake bite.

if you think you have been bitten by a coral snake, call 911 or other emergency services immediately.
