Alcatrazes lancehead
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

No anndirte ngal
- 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
Ina heewi waylondireede e: 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

Humpito
Over time, isolated snakes shrank in size, a process known as allopatric speciation, because their food supply was less nutritious.1
About 15,000 years ago, rising seas cut the island off from the mainland, and its snakes became isolated.1
The island was once used as a naval target practice area.1
Its small size and relatively large eyes are considered juvenile (paedomorphic) features.1
