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

Anaishi

Shallow warm Pacific waters from Japan and Taiwan to Australia, New Zealand and Hawaii, plus the west coast of Sumatra1

Bahari ya Pasifiki, Bahari ya Atlantiki, Bahari ya Timor na Arafura

Hula nini?

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

Jinsi ya kumtambua

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

Hufanya nini akiogopa?

When disturbed by day it hides, folding its tentacles inside the bell and flattening itself against the seabed.1

Akidunga

Toka majini na uondoe vipande vya mikono iliyonata (kwa glavu au kitambaa).
Kwa yavuyavu sanduku wa kitropiki: mimina siki kwenye sehemu zilizodungwa kwa angalau sekunde 30, omba msaada na uwe tayari kufanya CPR. Kwa mabotoli ya bluu na wengine wengi: suuza kwa maji ya bahari, kisha maji ya moto kupunguza maumivu.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Akikudunga: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

Ukweli

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
