Banded sea urchin
有毒液的棘刺The banded sea urchin is a spiny sea animal that lives on tropical reefs and in lagoons across the Indo-Pacific. It is active at night and hides in cracks or under rocks during the day. Its thin spines can deliver a sting, although the sting is not dangerous.1

怎麼認出牠
- It has a slightly oval shell (test) about 5 cm across.1
- It has two kinds of spines: short, slender spines that run from yellow to dark, and longer, thicker spines that are often banded with light and dark colour.1
- The longer spines reach 10 to 15 cm and can be blunt and hollow.1
- Five bare zones in a star pattern show on the middle of the shell, and these can look blue.1
常被誤認為: Dark forms can look like Diadema setosum or Diadema savignyi. Diadema savignyi is bigger, more uniformly black, and has five white spots on top of its shell and an orange ring around its anus. The most common mix-up is Echinothrix diadema, which can have banded spines when young. Echinothrix diadema has a very small, all-black anal papilla and blue-sheened spines, and its spines do not crush easily, unlike the spines of the banded sea urchin.1
毒液力量
尖銳的棘刺帶著毒液。踩到或抓到牠都會很痛。
牠的毒液有什麼作用?
The thinner, short spines are venomous, meaning they deliver venom through a sting. The sting is nasty, but the venom is not dangerous.1
牠對人有多危險?
對人的危險: 疼痛可能會非常痛,但幾乎從來不會很嚴重。The thinner spines are venomous but not dangerous.1
如果牠的棘刺刺到你
- 把傷口泡在熱水裡,水溫要在傷者能忍受、又不會燙傷的範圍內,並就醫請醫生取出棘刺。不要自己挖出來。
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。
- 如果被牠的棘刺刺到: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

小知識
Its anal papilla is large and whitish with black and white dots, and a ring of visual receptors around it gives it basic vision.1
Young cardinal fish from the family Apogonidae often hide among the spines for protection.1
In Hawaii, this sea urchin often carries a symbiotic crab, Echinoecus pentagonus, that lives with it.1
It is active at night and spends the day hidden in crevices or under rocks.1
