Net fire coral

Millepora dichotoma

只是会疼会疼，但不会对你造成严重伤害。

蜇伤吃：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

它吃什么？

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

怎样认出它

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

毒液之力

毒液通过蜇刺出来。

它的毒液会造成什么？

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

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。

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

如果它蜇人

离开水面，取下所有触手（戴手套或用布）。
热带箱水母：在蜇伤处倒醋至少 30 秒，呼救，并准备好做心肺复苏。僧帽水母和大多数其他水母：先用海水冲洗，再用热水止痛。

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。
如果被它蜇了：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

值得了解

事实

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

谣言粉碎机

谣言： 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
