Copula sivickisi is a tiny box jellyfish, about 1 cm across, that lives in shallow warm seas. It is the only species in its genus and is active only at night. It is unusual among box jellyfish because it has a mating ritual and fertilises its eggs inside the body.1

It lives in shallow warm waters. By day it hides on the underside of coral, stones or blades of seagrass, and at night it rises through the water to feed.1

牠吃什麼？

It feeds on zooplankton, including copepods, hooded shrimps, zoea larvae and the glowing dinoflagellate Noctiluca. It rises to the surface, then sinks with its tentacles spread out to catch prey.1

怎麼認出牠

The bell is boxy in shape, unlike the umbrella shape of true jellyfish.1
It has four slender tentacles hanging from the rim, each banded with orange.1
The eight gonads (reproductive organs) can be seen through the transparent bell. In males they are orange, and in females they are white-speckled.1
Mature females have orange-brown markings around the edge of the bell.1
It is most active at night and hides during the day, folding its tentacles inside the bell and flattening itself.1

會螫人的觸手

有東西碰到時，成千上萬個小小的刺細胞就會發射。

牠對人有多危險？

對人的危險: 輕微跟蜜蜂螫差不多或更輕微。對人基本上無害。

牠害怕時會做什麼？

When disturbed by day it hides, folding its tentacles inside the bell and flattening itself against the seabed.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

小知識

It has twenty-four eyes, grouped on four stalked structures called rhopalia on the rim of the bell.1

Unlike most box jellyfish, it has an elaborate mating ritual. A male grabs a female by one tentacle and pulls her around while they entwine.1

A female has been seen mating with several males, up to eight times in a two-hour period.1

It is attracted to light, and it chooses a spot on the seabed soon after dawn, spending a few minutes selecting a good location before settling there.1

Its average maximum swimming speed is 4.9 cm per second, which is faster than the currents near the surface of the shallow waters where it lives.1

The male passes a red bundle of sperm (a spermatophore) to one of the female's tentacles, which pushes it into her manubrium, the tube hanging from the underside of the bell.1
