Lachesis acrochorda, also known commonly as the Chocoan bushmaster,[3] is a species of pit viper in the family Viperidae.

[2] L. acrochorda has a light brown head and black postocular stripes that can range from 1-2 scales wide.

[2] L. acrochorda is found in Panama, northern and western Colombia (in the Departments of Chocó, Cauca and Antioquia), and northwestern Ecuador.

[1][2] The venom of L. acrochorda is extremely dangerous in that a snakebite incident will result in a 90% chance of death.

Its venom can cause serious side effects, such as vasodilation and blood anti-coagulation.
