Castellana is a rare pit viper, a venomous snake that lives in dry forests on the Pacific side of Central America. It is a stout, medium-sized snake. Scientists know little about its bites, but lab tests suggest its venom is highly toxic.1

怎样认出它

A stout, medium-sized snake, up to 96 cm long including the tail.1
Light to medium reddish-brown body with broad brown crossbands: 10 to 14 in males and 13 to 17 in females.1
Two pale stripes on each side of the head.1
Chin and throat are orange or orange-brown, lighter than the belly.1
Large adult males are often very dark. Young snakes are paler, sometimes bright red.1

常被误认为： Copperheads lack the two pale stripes on each side of the face, and cottonmouths lack the loreal scale (a small scale between the eye and nostril). Other cantils have a lower face stripe that runs straight and unbroken, while in this species it dips below the pit.1

咬伤

它咬的时候，毒液通过毒牙或牙齿出来。

它的毒液会造成什么？

Lab tests suggest the venom is highly toxic and similar to that of its close relative Agkistrodon bilineatus, and potentially lethal. No clinical reports of bites had been published as of 1999, so the effects on people are not well documented.1

它对人有多危险？

对人的危险: 非常危险不治疗可能会害死人。

No clinical reports of bites had been published as of 1999, so there is little human data on its danger. Lab analysis suggests the venom could be lethal.1

如果它咬人

让人保持安静不动，被咬的肢体与心脏保持同一高度，摘下戒指和紧身物品，尽快送医院。

一定先拨打你的急救电话（112、000、911）。这里是一般急救指导，不是医疗建议。急救基础

注意安全

永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。
给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
如果被它咬了：保持冷静，保持不动，拨打你的急救电话（112、000、911）或尽快去医院。记住它长什么样，拍张照片会有帮助。

它不是冲着你来的。它用毒液捕猎或保护自己，而且它更愿意躲起来。更多安全知识

事实

Its diet changes as it grows: young snakes eat cold-blooded prey such as frogs and lizards, while adults eat warm-blooded prey such as mice and rats.1

It is a rare snake, found only along a narrow strip of lowland less than 400 km long.1

In the 1990s, searches in the Gulf of Fonseca area of Honduras found very few, or possibly no, snakes.1
