What is Black-Speckled Palm Pitviper Snake Bite? (Definition/Background Information)

  • The black-speckled palm pitviper (Bothriechis nigroviridis) is a moderately venomous snake found in Central America, in the countries of Costa Rica and Panama. 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. The black-speckled palm pitviper can grow from over 1.5 feet to slightly above 3 feet in length
  • It preys on a variety of animals including small mammals and on frogs and birds (sometimes). It is a nocturnal hunting reptile that inhabits the cloud forest and high and lower montane forests, in elevations between 3,600 to 7,900 feet (1,100 to 2,400 m). The snake is well-adapted to climbing plants and trees; it is often found coiled on the branches, usually above waterbodies such as rivers and streams
  • The snake has a slender body with a prehensile tail; young snakes present a black tail tip. The head of the snake is broad, almost triangular in shape, and distinct from its neck; the snout of the reptile is not elevated. The body color of the black speckled palm pitviper is green (emerald-green or yellow-green) and crowded with black dots. A prominent black line is seen from its eye to the corner of its mouth. The snake’s belly is also in shades of green but with less dense black dots
  • Human contact with the viper snake is very uncommon; the snake is typically found away from human settlements. Even though timid and non-aggressive by nature, the snake will bite if provoked. The Black-Speckled Palm Pitviper Snake Bites can cause moderate to severe envenomation (venom injection) that may rarely result in deaths without early treatment. The venom is a potent mix of hemotoxins that may cause variable symptoms including bleeding issues and shock
  • The signs and symptoms of Black-Speckled Palm Pitviper Snake Bite may include moderate localized effects, such as pain at the bite site, swelling, and blistering. Systemic symptoms may include tissue necrosis, headache, nausea and vomiting, diarrhea, lightheadedness, and collapse
  • Early administration of suitable antivenom (or antivenin) is the mainstay of treatment for severe and significant envenomation presenting systemic presentations. Symptomatic treatment is important and may include pain medication, intravenous fluid administration, blood transfusion, and respiratory support, as needed. The prognosis of Black-Speckled Palm Pitviper Snake Bite with prompt and effective therapy is usually good; without proper treatment, the condition may result in fatalities
