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

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

Siyingozi kangakanani ebantwini?

Ingozi ebantwini: Kubi kakhuluUkulunywa kudinga udokotela. Ukufa kuyivelakancane kakhulu.

Uma siluma

Gcina umuntu engashukumi futhi ezolile, gcina isitho esilunyiwe sisezingeni lenhliziyo, khipha izindandatho nezinto eziqinile, bese umusa esibhedlela ngokushesha.

Njalo shayela kuqala inombolo yezimo eziphuthumayo (112, 000, 911). Lokhu kuyiseluleko sosizo lokuqala esijwayelekile, akusona iseluleko sezokwelapha. Izisekelo zosizo lokuqala

Hlala uphephile

Ungalokothi uthinte, ubambe noma ugcone isilwane sasendle, ngisho noma sincane, futhi ngisho noma sibukeka silele noma sifile.
Sinike isikhala. Uma uhlangana naso, hlala uzolile, uhlehle kancane bese usiyeka sihambe ngendlela yaso.
Uma sikuluma: hlala uzolile, ungashukumi, shayela inombolo yezimo eziphuthumayo (112, 000, 911) noma uye esibhedlela ngokushesha. Khumbula ukuthi besibukeka kanjani, isithombe siyasiza.

Asikuzingeli wena. Sisebenzisa ubuthi baso ukuze sibambe ukudla noma ukuzivikela, futhi singancamela ukucasha. Okwengeziwe mayelana nokuhlala uphephile

Amaqiniso

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
