Bothrops sazimai, or Franceses Island-lancehead, is a species of pit viper from Franceses Island, Brazil. [1]
It is named after Professor Ivan Sazima for his contribution to the study of natural history and conservation of Brazilian fauna, and for his field studies on Bothrops jararaca . [2]
Bothrops sazimai can be distinguished from other Bothrops species by its larger eyes, shorter and higher head, slender body, longer tail, grey/brown colouring, cream-white grey-speckled underbelly and the specific numbers of specific scales. [2]
Bothrops sazimai specifically differs from Bothrops jararaca by its smaller size, longer tail, slender body and larger eyes. It also differs from Bothrops alcatraz, Bothrops insularis and Bothrops otavioi by its larger number of ventral and subcaudal scales. Additionally it can be distinguished from B. insularis by its colour, smaller size, smaller head and smaller tail. Conversely, it can be distinguished from B. alcatraz and B. otavioi by its larger size as well as the yellow tip on juveniles' tails. [2]
Bothrops sazimai is known to eat nocturnal prey such as frogs, lizards ( Gymnodactylus darwinii and tropical house geckos), centipedes (Scolopendromorpha) and sometimes other snakes. [2] [3]
Bothrops atrox — also known as the common lancehead, fer-de-lance, barba amarilla and mapepire balsain — is a highly venomous pit viper species found in the tropical lowlands of northern South America east of the Andes, as well as the Caribbean island of Trinidad.

Bothrops is a genus of highly venomous pit vipers endemic to the Neotropics. The generic name, Bothrops, is derived from the Greek words βόθρος, bothros, meaning 'pit', and ὄψ, ops, meaning 'eye' or 'face', together an allusion to the heat-sensitive loreal pit organs. Members of this genus are responsible for more human deaths in the Americas than any other group of venomous snakes. Currently, 48 species are recognized.
Ilha da Queimada Grande, more commonly referred to as Snake Island, is an island off the coast of Brazil in the Atlantic Ocean. The island became famous for its abundant snakes, hence the name "Snake Island." It is administered as part of the municipality of Itanhaém in the State of São Paulo. The island is small, with an area of only 43 hectares, and has a temperate climate. Its terrain varies from bare rock to rainforest.
The terciopelo is a species of pit vipers, found from north-east Mexico to northern South America. At low to moderate elevations, its habitat ranges from northeastern Mexico to Colombian and Ecuadorian Andes, as well as Venezuela. With a mass of up to 6 kilograms (13 lb), and a maximal length of 2.5 metres (8.2 ft), the terciopelo is among the largest vipers. It is light to dark brown in color, often with yellowish, zig-zag patterning on either side of its body. Dubbed "the ultimate pit-viper" for its defensiveness, large size, fangs and potent venom yield, it has a fearsome reputation, responsible for the most envenomated snakebites within its range, largely due to its proximity to humans, livestock and pets. Nonetheless, like all venomous snakes, the terciopelo actively avoids contact with humans and larger animals, with bites generally only occurring when the snake is cornered, pursued, or threatened. No subspecies are currently recognized.
