About the Ribbon Coralsnake

Micrurus lemniscatus, commonly known as the South American coral snake, is a species of venomous snake in the family Elapidae. The species is endemic to South America.

Description

Micrurus lemniscatus is a thin and brightly colored species. Adults usually measure 60–90 cm (24–35 in) in length, and the maximum reported is 145 cm (57 in). The snout is black, followed by a narrow white crossband in front of the eyes, then a wider black band including the eyes. The eyes are small, and the rest of the head is red. The body pattern consists of slightly broad red rings that are separated by seven to 17 triads of three black and two white rings. The tail has two triads.

Behavior

Like many coral snakes, Micrurus lemniscatus is nocturnal and terrestrial, digging in loose soil or litter. It is not aggressive towards humans, although it can attack to defend itself.

Reproduction

Breeding of Micrurus lemniscatus is oviparous, having a clutch size of possibly 20 eggs.

Diet

Alimentation of Micrurus lemniscatus is mainly long-bodied vertebrates such as freshwater eels, gymnotiform fishes, caecilians, lizards, and snakes.

Geographic range

Micrurus lemniscatus is found in Argentina, northern Bolivia, Brazil, Colombia, eastern Ecuador, French Guiana, Guyana, Paraguay, eastern Peru, Suriname, Trinidad, and Venezuela.

Habitat

Micrurus lemniscatus is a widespread species in South America, living in humid forests and lowland forests, in open savannas and gallery forests. It is also found in lowland floodplains, deforested areas or near human habitation, in humid areas or near places with a water source. It occurs from near sea level to an altitude of 1,000 m (3,300 ft).

Venom

The venom of Micrurus lemniscatus is a potent post- and pre-synaptic neurotoxin, which causes a potent and irreversible neuromuscular block in vertebrates. Lemnitoxin, a potent myotoxic PLA2 type toxin, isolated from the venom of M. lemniscatus induces local and systemic myotoxicity after intramuscular and intravenous injection in mice, which is antigenically related to Micrurus nigrocinctus nigroxin, Notechis scutatus notexin, mulgotoxin of Pseudechis australis and textilotoxin of Pseudonaja textilis.

If you are bitten by the Ribbon Coralsnake

A venomous snakebite is a medical emergency. Call your local emergency number immediately. In the US, dial 911 or Poison Control at 1-800-222-1222.

Do

  • Get away from the snake and stay calm. Most bites worsen when people panic or try again to handle the snake.
  • Call 911 or Poison Control (1-800-222-1222) right away. Antivenom works best when given early.
  • Note the time of the bite and, from a safe distance, the snake's color and pattern, a phone photo is enough. Do not chase it.
  • Keep the bitten limb still and at roughly heart level. Sit or lie down and limit movement.
  • Remove rings, watches, and tight clothing near the bite before swelling starts.
  • Gently wash the bite with soap and water and cover it with a clean, dry dressing.

Do not

  • Do not cut the wound or try to suck out the venom.
  • Do not apply a tourniquet or ice.
  • Do not drink alcohol or caffeine.
  • Do not take aspirin or ibuprofen, they can worsen bleeding. Acetaminophen is safer for pain.
  • Do not try to catch or kill the snake. A dead snake can still bite by reflex.
