The Alcatrazes lancehead is a small pit viper, a venomous snake that senses heat with pits on its face. It lives only on Ilha Alcatrazes, a small island off the coast of southeastern Brazil. It is special because its island home has shaped it over thousands of years into a snake that stays small.1

Yadda za ka gane shi

  • A small pit viper, reaching a maximum length of about 46 cm in males and 50 cm in females.1
  • Relatively large eyes for its body size.1
  • Found only on the Alcatrazes Islands, so it is not expected anywhere else in Brazil.1

Ana yawan rikita shi da: Its island population was once connected to the mainland, where the common Bothrops still lives. Its small size and large eyes set it apart from these larger relatives.1

Bayanai

1

Over time, isolated snakes shrank in size, a process known as allopatric speciation, because their food supply was less nutritious.1

2

About 15,000 years ago, rising seas cut the island off from the mainland, and its snakes became isolated.1

3

The island was once used as a naval target practice area.1

4

Its small size and relatively large eyes are considered juvenile (paedomorphic) features.1
