[4] Bothrops species are found in northeastern Mexico (Tamaulipas) southward through Central and South America to Argentina.

They also occur on the islands of Saint Lucia and Martinique in the Lesser Antilles, as well as on Ilha da Queimada Grande off the coast of Brazil.

One species, B. insularis, which is endemic to Ilha da Queimada Grande, is considered to be semi arboreal.

[2] Typical symptoms of bothropic envenomation include immediate burning pain, dizziness, nausea, vomiting, sweating, headache, massive swelling of the bitten extremity, hemorrhagic blebs, local necrosis, bleeding from the nose and gums, ecchymosis, erythemia, hypotension, tachycardia, coagulopathy with hypofibrinogenemia and thrombocytopenia, hematemesis, melena, epistaxis, hematuria, intracerebral hemorrhage, and kidney failure, secondary to hypotension and bilateral cortical necrosis.

[2] In general, death results from hypotension secondary to blood loss, kidney failure, and intracranial hemorrhage.

Common complications include necrosis and kidney failure secondary to shock and the toxic effects of the venom.
