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

Leef in

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

Stille Oseaan, Atlantiese Oseaan, Timorsee & Arafurasee

Tuis

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

Lengte

1 cm (0,4 in)1

Wat eet dit?

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

Hoe om dit te herken

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

Gifkrag

Steektentakels

Duisende piepklein steekselle skiet af wanneer iets aan hulle raak.

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: LigSoos 'n bysteek of minder. Basies onskadelik vir mense.

Wat doen dit as dit bang is?

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

As dit steek

Klim uit die water en pluk enige tentakels af (met handskoene of 'n lap).
Vir tropiese kubuskwalle: gooi vir minstens 30 sekondes asyn oor die steke, roep hulp en wees gereed om KPR te doen. Vir bloublasies en die meeste ander: spoel af met seewater, dan warm water vir die pyn.

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou steek: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

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
