Mangrove box jellyfish

Tripedalia cystophora

无害对人无害。不用担心。

会蜇人的触手吃：肉

The mangrove box jellyfish is a small, boxy jellyfish about 1 cm across. It lives in sunlit water among mangrove roots in the Caribbean Sea, the Central Indo-Pacific and off the north coast of South America. Its bell is see-through, so it can be hard to spot.1

During the day it stays within 20 cm of the surface, in sunlit spots among the prop roots of mangrove trees. At night it moves a few metres further into the shallow lagoon. One colony was found along the edges of mangrove lagoons in Puerto Rico.1

它吃什么？

It feeds mainly on the copepod Dioithona oculata, a tiny crustacean. It sinks slowly towards the bottom with its tentacles spread out around it to catch prey.1

毒液之力

会蜇人的触手

一碰到东西，成千上万个小刺细胞就会发射。

它对人有多危险？

对人的危险: 轻微像被蜜蜂蜇一下或更轻。对人基本无害。

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

It has six eyes in each of its four rhopalia, which are structures on the bell that contain light-sensitive cells.1

It can spot a cylindrical object such as a mangrove root when it gets close and swerve sharply to avoid it.1

It stays in shafts of sunlight where its copepod prey gathers, which helps it catch more food.1

Its life cycle includes a small polyp stage that attaches to the seabed before young jellyfish form.1

给毒液专家

学名: Tripedalia cystophora
类别: 水母和海中蜇人生物
家人: Tripedaliidae2
排序: Carybdeida
大洲: 大西洋, 加勒比海, 太平洋, 海洋
宝宝: After fertilisation, the female broods the planula larva inside her bell until it is expelled. The larva settles on the bottom and becomes a small polyp, which can bud new polyps and eventually produce young jellyfish.1
