What is Whitetail Lancehead Snake Bite? (Definition/Background Information)

  • The whitetail lancehead (Bothrops leucurus) is a moderately venomous snake that ranges in size from 3.5 to nearly 6.5 feet in length. The snake belongs to the subspecies of pit vipers, family Viperidae. Pit vipers are termed so, due to the presence of certain heat-sensing organs located in a recess/notch between their eyes and nostrils
  • This reptile is found at elevations of up to about 1,300 feet (400 m) in the tropical rainforest and deciduous forests of Brazil in the South American continent. In the endemic regions, the snake is also found on deforested agricultural lands. It is a nocturnal snake that hunts at night, preying mainly on small mammals (rodents), birds, lizards, and frogs
  • The whitetail lancehead snake has a slender to medium sized body with a short tail. The head of the snake is broad and shaped like a lance (spear) and distinct from its neck. The snake color is usually brown to red-brown, with a series of pale (appearing as diagonal white bands) and dark markings. The snake’s belly is white/yellow with dense irregular dark blotches and spots along the sides
  • Whitetail Lancehead Snake Bites involving humans are very uncommon. Even though infrequent, a bite from a fully-grown snake has the potential to result in severe envenomation (venom injection) with significant symptoms, in the absence of adequate treatment. The snake venom is a potent mix of hemotoxins and myotoxins that can cause hypovolemic shock and renal injury
  • In general, the signs and symptoms of Whitetail Lancehead Snake Bite may include moderate to severe pain at the bite site and local swelling with bruising, blistering, and tissue necrosis. In case of systemic symptoms, the bite can result in headache, nausea and vomiting, abdominal pain, diarrhea, seizures, and collapse
  • Early administration of suitable antivenom (or antivenin) is the mainstay of treatment. Apart from this, symptomatic treatment is necessary, which may include the use of pain medication, wound care, blood transfusion, and breathing support, if needed. The prognosis of Whitetail Lancehead Snake Bite with prompt and effective therapy is usually good; fatalities may take place infrequently
