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

Sida loo aqoonsado

  • 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

Inta badan lagu khaldaa: 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

Awoodda sunta

Qaniin

Suntu waxay ka soo baxdaa ilkihiisa sunta ama ilkihiisa marka uu qaniino.

Intee buu dadka khatar ugu yahay?

Khatarta dadka: HalisQaniinyo waxay u baahan tahay dhakhtar. Dhimashadu aad bay u yar tahay.

Haddii uu qaniino

  • Qofka ka dhig mid aan dhaqaaqin oo deggan, xubinta la qaniinay ku hay heerka wadnaha, ka saar faraantiyada iyo waxyaabaha adag, si degdeg ahna u geey isbitaalka.

Marka hore had iyo jeer wac lambarka gurmadka degdegga ah (112, 000, 911). Kani waa hage guud oo gargaar degdeg ah, ma aha talo caafimaad. Aasaaska gargaarka degdegga ah

Badbaado

  • Weligaa ha taaban, ha qaban, hana ku ciyaarin xayawaan duurjoog ah, xitaa mid yar, xitaa haddii uu u muuqdo inuu hurdo ama dhintay.
  • Meel u bannee. Haddii aad mid la kulanto, deg, tartiib dib ugu noqo oo u daa inuu jidkiisa maro.
  • Haddii mid ku qaniino: deg, ha dhaqaaqin, wac lambarka gurmadka degdegga ah (112, 000, 911) ama si degdeg ah u tag isbitaalka. Xusuuso sida uu u egyahay, sawir ayaa caawiya.

Kuma raadinayo. Suntiisa wuxuu u isticmaalaa inuu cunto ku qabsado ama isku difaaco, wuxuuna aad u door bidaa inuu dhuunto. Wax badan oo ku saabsan badbaadada

Xaqiiqooyin

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
