Check Out These Ssseriously Cool Black-Headed Bushmaster Facts


The Lachesis genus is composed of bushmasters or pit vipers in the forests of South and Central America. Four separate species have been grouped under the genus namely the Chocoan bushmaster (Lachesis acrochorda), South American bushmaster (Lachesis muta), black-headed bushmaster (Lachesis melanocephala), and Central American bushmaster (Lachesis stenophrys). One of the longest vipers found in the Neotropics, the black-headed bushmaster is a deadly venomous snake that you would want to steer clear of. Initially, these snakes were considered a subspecies of the South American bushmaster but research rendered the species its unique identity. Endemic to the tropical rainforests of Costa Rica, the species is believed to be nocturnal and crepuscular but during rains, a great amount of activity has been noticed in the afternoons. These reptiles are terrestrial that love to remain on their own.

Did you know that human activities such as deforestation can eradicate the species from existence? Towards the north, the lowland forests on the foothills of Puerto Viejo de Talamanca were converted for the production of coffee. A large number of low montane rainforests were reclaimed for commercial purposes due to which the habitat of several burrowing animals is lost. Loss of habitat and scarcity of food are major concerns that threaten the conservation status of these pit vipers. Conservation of the bushmasters, therefore, becomes crucial as the species can rarely be seen outside Costa Rica.
