What is Eastern Coral Snake Bite? (Definition/Background Information)

  • The eastern coral snake (Micrurus fulvius) is a moderately venomous snake that is found in the southeastern region of United States of America. The snake belongs to the Elapidae family that generally includes slender and swift moving snakes, of genus coral snakes (Micrurus) that form a large group of elegant and ‘mostly’ brightly colored and banded venomous reptiles
  • The body of the snake is slender to medium, and it has a small, rounded head and blunt snout. The head and neck of the snake are almost continuous (same size). The body is typically cylindrical and uniform in size, and it has a short tapering tail. The tail does not mimic the head, such as noted in some coral snake species
  • Like many colorful and glossy coral snakes, the eastern coral snake is characterized by a black head with broad yellow band. The snake presents alternating red and black broad bands interspersed by narrow yellow rings. The snake’s tail may have alternating black and yellow bands. The snake may range in size from over 1.5 feet to slightly over 4 feet in length
  • The eastern coral snake is terrestrial and generally feeds on small lizards and other snakes, including other coral snakes, usually hunting in the early mornings. The snake is found in the mesquite-grassland, pine-oak forest, thorny forest and desert, and rocky hillsides and canyons. It is particularly seen in moist areas such as under rotting logs or leaf litter, near streams, rivers, and lakes. The snake may be seen in altitudes of up to 1,300 feet (400 m)
  • Like many coral snakes, the snake is typically solitary and docile and tends to silently move away when disturbed. Eastern Coral Snake Bites can rarely result in fatalities due to systemic envenomation (venom injection through a bite) in the absence of treatment. The potent myotoxic-neurotoxic venom released can cause systemic effects including significant muscle damage and respiratory distress
  • The signs and symptoms of Eastern Coral Snake Bite may include mild local effects at the bite site such as pain and swelling. As various body systems gets rapidly affected by the venom, it can result in widespread symptoms including convulsions, dizziness, flaccid paralysis, and kidney failure
  • Early administration of suitable antivenom (or antivenin) is the mainstay of treatment. Apart from this, symptomatic treatment is necessary, which may include pain medication, IV fluid administration, respiratory support, and peritoneal dialysis, if required. The prognosis of Eastern Coral Snake Bite with prompt and effective therapy is usually good, but deaths have been reported without adequate treatment
