Ringed caecilian

Siphonops annulatus

無害對人無害。不用擔心。

咬有毒（碰或吃會中毒），不是有毒液

The ringed caecilian is a legless-looking amphibian that lives mostly underground in South America. It is one of the few amphibians known to feed its young with a milk-like liquid, which makes it a remarkable animal to learn about. It is also one of the caecilians with the widest known spread across the continent.1

有毒還是有毒液？有毒液的動物會用咬或螫把毒液注入身體。有毒的動物則是碰到或吃下去會有害。這種動物是有毒的（碰或吃會中毒）。

It lives in moist and dry lowland forest, savanna, grassland, pastureland, plantations, rural gardens and heavily degraded former forest. It spends most of its life burrowing underground, so people are most likely to meet it in gardens, plantations or fields when the soil is turned.1

長度

29 cm 到 45 cm (11,3 in 到 1,5 ft)1

最高速度

大約 0,5 km/h（0,31 mph）

怎麼認出牠

Bluish-black to slate-coloured body1
Cylindrical body that is slightly wider than it is deep1
Rings of grooves that encircle the body, edged in white or cream (the last three or four grooves at the tail end are not edged)1
Total length of 28.6 to 45 cm1

毒液力量

咬

咬的時候，毒液會從毒牙或牙齒出來。

牠的毒液有什麼作用？

This animal is not venomous. Glands in the tail region are packed with noxious chemicals, similar to the poison glands of toads and newts.1

牠對人有多危險？

對人的危險: 輕微跟蜜蜂螫差不多或更輕微。對人基本上無害。

如果牠咬人

如果有人碰了牠：把手徹底洗乾淨，不要碰眼睛或嘴巴。如果小孩或寵物舔了或吃了牠：打給毒物諮詢中心或打緊急電話。

一定要先打緊急電話（112、000、911）。這是一般急救指引，不是醫療建議。急救基本知識

注意安全

絕對不要碰、抓或捉弄野生動物，就算是很小的動物，就算牠看起來在睡覺或已經死了也一樣。
給牠空間。如果遇到了，保持冷靜，慢慢往後退，讓牠自己離開。
如果被牠咬了：保持冷靜，保持不動，打緊急電話（112、000、911）或趕快去醫院。記住牠的樣子，有照片會很有幫助。

牠不是想來抓你。牠用毒液來捕捉食物或保護自己，而且牠更想躲起來。更多安全知識

牠有多大？

牠有多長？

跟 2,5 根香蕉頭尾相接一樣長跟 14 塊玩具積木排成一排一樣長

Ringed caecilian 跟「你」比起來有多大？

牠有多快？

一隻陸龜 大約 0,3 km/h (0,19 mph)

Ringed caecilian 大約 0,5 km/h (0,31 mph)

一個正在走路的人 大約 5 km/h (3,1 mph)

值得知道

小知識

Mothers and young share an unusual feeding habit: the young scrape off the mother's outer skin in one feeding session of about seven minutes, then the mother rests for three days while she grows a new skin layer.1

Hatchlings make high-pitched clicking sounds when they approach their mothers for milk, a behaviour unique among amphibians.1

Glands on its head produce a slippery mucus that may help it burrow.1
