名字的由来： The specific name greeningi honours Linnaeus Greening (1855–1927), an English businessman and naturalist known for his work on arachnids, reptiles and amphibians.1

只是会疼不要触摸会疼，但不会对你造成严重伤害。

毒蛙、蟾蜍和蝾螈

有毒的刺碰了或吃了有毒，不注射毒液

对人的危险: 很疼可能真的很疼，但几乎从不严重。

Greening's frog is a small tree frog that lives in the dry thorn scrub of eastern Brazil. It is venomous: it has spines on its skull that can inject venom when it headbutts. It is special because it survives a semi-desert climate by hiding in tree hollows, rock cracks and bromeliads.1

有毒还是有毒液？有毒液的动物通过咬或蜇注入毒液。有毒的动物是碰了或吃了会受害。这一种是碰了或吃了有害的。

怎样认出它

Light brown or grey body, blotched with red or brown patches1
Females are generally darker than males1
Narrow head with bony crests behind the eyes and a long flat snout with small spines1
Warty skin on a slender body and legs1
Well-developed adhesive discs on the tips of the fingers and toes1

毒液之力

有毒的刺

锋利的刺带着毒液。踩到或抓住它会很疼。

它的毒液会造成什么？

Its skull spines inject venom into other animals, or into a human hand, when it headbutts. Its skin secretions contain steroids and alkaloids, which in laboratory tests caused a powerful painful effect and swelling in mouse cells. In the wild these secretions act as a chemical defence against predators.1

它对人有多危险？

对人的危险: 很疼可能真的很疼，但几乎从不严重。

它害怕时会做什么？

It hides in a tree hollow, rock crevice or bromeliad, sealing the entrance with its head, and it defends itself by headbutting with its skull spines.1

如果它的刺扎到你

如果有人碰了它：好好洗手，不要碰眼睛或嘴巴。如果孩子或宠物舔了或吃了它：打电话给中毒急救中心或急救电话。

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。
如果它的刺扎到你：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

Unlike poison dart frogs, which only secrete poison from their skin, this frog can inject venom through spines on its skull.1

The skin of its head is fused to the skull to form a casque, a hard helmet-like structure.1

In laboratory tests, its skin secretions also slowed the growth of mouse fibroblast and melanoma cells.1

It has a tough, water-resistant skin and a low metabolic rate, which help it survive the dry semi-desert climate.1

When the rains start and the streams run with water, males set up territories near the water and call to attract females.1

It shares its headbutting, spine-injecting defence with another frog, Nyctimantis brunoi.1
