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

Živi v

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

Tihi ocean, Atlantski ocean, Timorsko in Arafursko morje

Domov

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

Kaj je?

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

Kako jo prepoznaš

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

Če piči

Pojdi iz vode in odstrani lovke (z rokavicami ali s krpo).
Pri tropskih kockastih meduzah: pike vsaj 30 sekund polivaj s kisom, pokliči pomoč in bodi pripravljen na oživljanje (TPO). Pri portugalskih ladjicah in večini drugih: izperi z morsko vodo, nato pa za bolečino uporabi vročo vodo.

Vedno najprej pokliči številko za klic v sili (112, 000, 911). To so splošna navodila za prvo pomoč, ne zdravniški nasvet. Osnove prve pomoči

Ostani varen

Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
Če te piči: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti

Dejstva

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
