The blue blubber jellyfish is a large, rounded jellyfish that lives along the coast of Eastern Australia. It is blue to purple and pulses slowly as it swims. Its arms carry stings, and it can form huge blooms in estuaries and shallow bays.1

Leef in

Eastern Australian coastline; also found along the Malay Peninsula1

Indiese Oseaan, Stille Oseaan, Koraalsee

Tuis

It lives in estuaries, semi-enclosed lagoons and shallow bays, and mostly in the saltier parts of estuaries. It can form large, dense blooms, which can interrupt people's use of beaches and coastal waters.1

Lengte

25 cm tot 30 cm (9,8 in tot 1 ft)1

Topspoed

omtrent 0,9 km/h (0,56 mph)

Swem, rowwe skatting

Wat eet dit?

It feeds mainly on zooplankton (tiny animals drifting in the water), especially mollusc veligers, copepods and their nauplii. It uses stinging cells on its arms to immobilise prey.1

Hoe om dit te herken

Colour ranges from light blue to dark blue or purple.1
Large, rounded bell, about 25 to 30 cm across.1
The bell pulses in a rapid, staccato rhythm.1
Found along the Eastern Australian coast, often in large numbers.1

Word dikwels verwar met: Two forms are recognised on the Eastern Australian coast. Catostylus mosaicus mosaicus, found in New South Wales and southern Queensland, has small or no papillae (small projections) and a larger bell. Catostylus mosaicus conservitus, found in the Bass Strait, has clear papillae, is blue or white, and has a smaller bell.1

Gifkrag

Steektentakels

Duisende piepklein steekselle skiet af wanneer iets aan hulle raak.

Wat doen sy gif as dit byt of steek?

Its arms carry stinging cells and can produce a mild but irritating sting. The sting is described as mild, and no further effects on the body are described.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: PynlikDit kan regtig seermaak, maar dit is amper nooit ernstig nie.

Its sting is described as mild but irritating. The main problem is the large blooms, which can interrupt recreation in coastal areas.1

Wat doen dit as dit bang is?

Its stinging cells on the arms are used to defend it from threats.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

die moeite werd om te weet

Feite

Its stinging venom is being studied for possible anticancer effects against lung cancer cells in laboratory research.1

It is harvested for food and is considered a delicacy in some countries, including China and Japan.1

A small copepod lives on its oral arms and is thought to feed on mucus the jellyfish produces.1

Blooms can be very dense, and they can take food away from other animals such as fish.1

Sea turtles and jellyfish-eating fish, including tuna, butterfish, sunfish and spiny dogfish, prey on it.1

It has a partnership with photosynthetic algae, though it has less of these algae than many other jellyfish.1

Wetenskaplike naam: Catostylus mosaicus

Familie: Catostylidae2
Orde: Rhizostomeae
Kontinente: Indiese Oseaan, Stille Oseaan, Koraalsee, Die oseane
Babas: Fertilised eggs develop into free-swimming planula larvae, which settle on the seabed and grow into a polyp stage. The polyp then produces young jellyfish (ephyrae), which mature into the free-swimming medusa.1
