Net fire coral

Millepora dichotoma

只是會痛會痛，但不會對你造成嚴重傷害。

螫吃：肉

The net fire coral is a colony-forming sea animal that looks like coral. It builds hard, lacy or box-shaped structures and lives in shallow tropical seas. Its sting is painful, so it is one to admire from a distance.1

It lives on the seabed at depths of about 0.2 to 3 metres. It attaches itself to hard surfaces, and people can meet it when walking, snorkelling or diving on and around it.1

長度

60 cm (2 ft)1

最高速度

大約 0,01 km/h（0,01 mph）

牠吃什麼？

It is a suspension feeder. Its polyps catch plankton and detritus (small bits of dead material) drifting in the surrounding water, then digest them in an internal cavity.1

怎麼認出牠

Forms colonies up to 60 cm wide, and clumps of colonies may be several metres across.1
Starts as a flat, crust-like layer stuck to hard surfaces, then grows into lace-like, leaf-like blade or box-work shapes.1
Lace-like forms are more fragile and grow best in deeper, calmer water. Box-work forms cope better with harsher conditions.1
Has vibrant colours, given by symbiotic algae called zooxanthellae that live inside its tissues.1

毒液力量

毒液從螫針出來。

牠的毒液有什麼作用？

Its stinging cells, called nematocysts, carry venom. The venom is fatal to many organisms but has not been found to be fatal to humans. Contact can cause extreme pain and burn-like wounds.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。

Its sting has not been found to be fatal to humans. It can cause extreme pain, burn-like wounds and skin irritation that may last for up to two weeks.1

如果牠螫人

離開水裡，把觸手拿掉（戴手套或用布）。
熱帶箱形水母：在螫傷處倒醋至少 30 秒，求救，並準備好做心肺復甦術（CPR）。藍瓶水母和大多數其他水母：用海水沖洗，再用熱水止痛。

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。
如果被牠螫了：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

Net fire coral 跟「你」比起來有多大？

牠有多快？

一隻海馬 大約 0,0015 km/h (0 mph)

Net fire coral 大約 0,01 km/h (0,01 mph)

一隻花園蝸牛 大約 0,05 km/h (0,03 mph)

值得知道

小知識

Its polyps catch floating food with stinging cells as well as with their feeding structures.1

When a colony breaks apart, its structure can change, for example from fragile lace-like growth to thicker box-work.1

Its colours come from symbiotic zooxanthellae, which also help it grow and recycle nutrients.1

A single colony can grow into a shape that depends on depth, location and how cloudy the water is.1

破解迷思

迷思： Net fire coral stings are deadly to people.

真相： Its venom is fatal to many organisms, but it has not been found to be fatal to humans. Its sting is still very painful and can leave burn-like wounds.1
