The Mediterranean box jellyfish is a small, see-through jellyfish with a box-shaped body about 3 cm across. It lives only in the Mediterranean Sea, where it is the only box jellyfish, and its sting can hurt people who swim in shallow water.1

Leef in

Mediterranean Sea, the only box jellyfish found in that sea1

Atlantiese Oseaan, Middellandse See

Tuis

It lives in the upper few metres of the open sea and often moves through shallow water. Swimmers in the Mediterranean are the people most likely to meet it.1

Lengte

3 cm (1,2 in)1

Topspoed

omtrent 5 km/h (3,1 mph)

Swem, rowwe skatting

Wat eet dit?

It eats invertebrates and even small fish. It catches prey with stinging cells, called nematocysts, on its tentacles, often in shallow waters.1

Hoe om dit te herken

Transparent, box-shaped bell about 3 cm across1
Four long tentacles at the lower corners of the bell, up to 30 cm long1
Red banding on the tentacles1
Small white or yellowish warts on the bell that carry stinging cells1
Often found in small groups1

Word dikwels verwar met: Other box jellyfish of the genus Carybdea look similar, but they live in warm oceans elsewhere. The red banding on the tentacles is the feature that separates this species from them.1

Gifkrag

Steektentakels

Duisende piepklein steekselle skiet af wanneer iets aan hulle raak.

Wat doen sy gif as dit byt of steek?

Its sting is venomous to humans, but some swimmers feel no painful sensation at all. In severe cases the symptoms spread through the body, with pain at the sting site and elsewhere, paresthesia (abnormal prickling or tingling sensations), hyperesthesia (over-sensitive skin) and skin lesions. These symptoms can take a few months to fully disappear.1

Hoe gevaarlik is dit vir mense?

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

It is far less dangerous than some box jellyfish species from other parts of the world. It is still considered the second-most significant stinging jellyfish in the Mediterranean, after Pelagia noctiluca.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.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

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

Hoe groot is dit?

omtrent so lank soos 'n skuifspeldkan die lengte van 'n groot swembad (50 m) in 36 sekondes swem

Hoe groot is Mediterranean box jellyfish in vergelyking met JOU?

Net wiskunde in jou blaaier. Niks word gestoor of enige plek heen gestuur nie.

Hoe vinnig is dit?

'n Mens wat swem omtrent 3 km/h (1,9 mph)

Mediterranean box jellyfish omtrent 5 km/h (3,1 mph)

'n Olimpiese swemmer omtrent 8 km/h (5 mph)

Feite

It has comparatively sophisticated eyes with lenses, which help it detect and avoid obstacles such as posts or a ship's rudder.1

After a free-swimming larva forms, it develops into a polyp that can reproduce by budding, and it can regenerate missing parts within 72 hours.1

It swims by making rapid contractions of its bell, moving between 3 and 6 metres per minute.1

Its tentacles can grow up to 30 cm long, many times the width of its box-shaped bell.1

It is the only box jellyfish found in the Mediterranean Sea.1
