Banded sea urchin
有毒的刺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

怎样认出它
- 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
常被误认为: 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
毒液之力
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?
The thinner, short spines are venomous, meaning they deliver venom through a sting. The sting is nasty, but the venom is not dangerous.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。The thinner spines are venomous but not dangerous.1
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
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
