The spotted jelly is a jellyfish with spots on the top of its bell, the rounded body. It lives in the warm Indo-Pacific oceans, and in some saltwater lakes in Palau and Indonesia. Its lake populations are famous because they have lost most of their sting.1

Leef in

Indo-Pacific oceans, from the Fijian archipelago to the western Indian Ocean, and from Japan to Australia1

Stille Oseaan, Indiese Oseaan, Koraalsee, Filippynse See, Timorsee & Arafurasee

Tuis

Lives in the open ocean across the Indo-Pacific, and in marine lakes, which are saltwater lakes cut off from the sea. Some Palau populations gather in huge groups called smacks, which are tourist attractions. The best-known spot is Ongeim'l Tketau Lake in Palau, also called Jellyfish Lake.1

Lengte

10 cm tot 30 cm (3,9 in tot 1 ft)1

Topspoed

omtrent 0,54 km/h (0,34 mph)

Swem, rowwe skatting

Wat eet dit?

Feeds on zooplankton and other tiny organisms, which it catches with its stinging cells. It also gets much of its nutrition from photosynthetic algae called zooxanthellae that live inside its tissues.1

Hoe om dit te herken

Distinctive spots on the top of the bell1
Colour ranges from greenish blue to olive green, from the algae living in its tissues1
Eight rhopalia (sensory organs) along the edge of the bell1
Eight frilled oral arms, each ending in a club-like appendage1
Numerous small mouths along the bottom of the oral arms, unlike many other jellies1

Gifkrag

Steektentakels

Duisende piepklein steekselle skiet af wanneer iets aan hulle raak.

Wat doen sy gif as dit byt of steek?

The venom is protein-based and is delivered by stinging cells called nematocytes (cnidocytes) on the upper surfaces of the oral arms. In jellyfish living in marine lakes, conditions in the lake are thought to break down this venom, so those populations do not sting humans.1

Hoe gevaarlik is dit vir mense?

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

Jellyfish in the open ocean have stinging cells on their oral arms. Populations in marine lakes, such as Jellyfish Lake in Palau, do not sting humans.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

Lake populations of spotted jellies have lost most of their ability to sting, probably after being cut off in marine lakes long ago.1

Each day, spotted jellies rise to the surface and follow the sun from east to west, so their algae can photosynthesise.1

Lake jellyfish are over three times wider than ocean ones, yet their tentacles are about the same length.1

Unlike many jellies, spotted jellies have several small mouths along their oral arms.1

A sea anemone called Entacmaea medusivora preys on spotted jellies, catching them in its tentacles.1

At night they stay lower in the water column.1

Mite-breker

Mite: All spotted jellies sting people.

Waarheid: Ocean populations have stinging cells, but the jellyfish in marine lakes such as Jellyfish Lake in Palau do not sting humans.1
