Screenclip of the Wiki entry for the snake Bothrops asper. Text reads: "Common names "Some of the common names applied to this snake are terciopelo ("velvet" in Spanish), fer-de-lance, mapepire balsain (Trinidad), carpet labaria (Guyana), barba amarilla (Guatemala, Honduras, Nicaragua; "yellow beard"), equis (Ecuador and Panama; "x"), talla equis, mapaná (Colombia), mapanare (Venezuela), nauyaca (México; from Nahuatl nahui, four, and yacatl, nose; "four noses"), and yellow-jaw tommygoff (Belize)."

Two snake species inhabit the island: the Golden Lancehead (Bothrops insularis) and the Neotropical Snail-eater (Dipsas mikanii).

The Golden Lancehead evolved differently from its mainland relative, the common Jararaca (Bothrops jararaca). The island lancehead is arboreal.

There are many curious facts about Snake Island, but the most notable is its endemic species: the Golden Lancehead (Bothrops insularis).
October 9, 2026 at 1:50 PM

The species Bothrops insularis originated from geographic isolation during the Earth's ice age 10,000 years ago. When melting waters began to submerge the land, many islands were formed. Most animals fled to the mainland, but some snakes remained trapped.

The reason they live in trees is their primary food source: migratory birds. The Golden Lancehead is smaller and lighter than Bothrops jararaca, measuring between 0.5 and 1 meter on average, though it can reach up to 2 meters. Its coloration is also distinct: a uniform ochre to light brown.

Surucucu (Lachesis) ist die tödlichste Schlange Brasiliens. Gefolgt von der Cascavel (Crotalus). Am häufigsten sind aber Unfälle mit den Jararacas (Bothrops). Die Cobra Coral (Micurus, 38 Arten in Brasilien!!!), spielt medizinisch keine Rolle, obwohl das stärkste Gift. Hier alle Fakten:

Boipeva (Xenodon merremii): Some feature colorations similar to the jararaca (Bothrops jararaca). However, this species' most specific mimicry tactic is flattening its body dorsoventrally to appear larger before launching defensive strikes at predators.

A bright yellow Golden Eyelash Viper [Bothrops schlegelii] photographed against a dark shaded background in the understory of Gandoca-Manzanillo National Wildlife Refuge, Costa Rica This is a viper and very venomous so the brilliant yellow coloration is good protection for it and anyone who comes too close. A fine warning!

A team led by João Miguel Alves-Nunes of the University of São Paulo won this year’s Biology Ig Nobel “for gently stepping on various parts of various venomous snakes—repeatedly, at various temperatures at various times of day—to try to learn what does and what does not induce a venomous snake to bite a human,” according to the award citation. While wearing safety boots, the researchers lightly laid a foot down on or near 116 Bothrops jararaca venomous pit vipers. They found that younger and smaller snakes tend to bite more often and that the snakes tend to bite during the daytime, in warm weather, and when stepped on. The controversial study was retracted following concerns about the paper’s animal work (Sci. Rep. 2024, DOI: 10.1038/s41598-025-88686-x).
