Portuguese man o' war

Physalia physalis

Oor die naam: The name comes from the man-of-war, a sailing warship, because the float looks like the Portuguese caravel (a sailing ship) under full sail.1

The Portuguese man o' war looks like a jellyfish, but it is actually a colony of many tiny linked animals that work together as one. It drifts on the surface of the Atlantic, Indian and Pacific oceans, and its long tentacles sting prey. Its sting is painful to people, and in some cases it can kill them.1

Leef in

Atlantic, Indian and Pacific oceans; drifts with winds and currents and can be washed onto beaches.1

Atlantiese Oseaan, Stille Oseaan, Indiese Oseaan, Middellandse See, Karibiese See, Golf van Meksiko

Tuis

It lives on the surface of the water, as part of a group of animals called the neuston. Winds can blow it into bays or onto beaches, where beachgoers are most likely to meet it. A man o' war found on a beach may lead to the beach being closed.1

Lengte

Wat eet dit?

It traps and paralyses prey with its venomous tentacles, then reels the prey in to its digestive zooids. It mainly eats small fish, molluscs, small crustaceans and zooplankton.1

Hoe om dit te herken

A gas-filled bladder called the pneumatophore floats on the surface and acts as a sail.1
Long tentacles, which can reach over 30 m, hang below the surface.1
The float can be up to 30 cm long, 13 cm wide and 15 cm tall.1
Groups can be large, sometimes over 1,000 animals.1
The sail may be left- or right-handed, depending on the way the wind catches it.1

Word dikwels verwar met: It superficially resembles a jellyfish, but it is a siphonophore, a colonial animal made of many smaller units called zooids.1

Gifkrag

Steektentakels

Duisende piepklein steekselle skiet af wanneer iets aan hulle raak.

Wat doen sy gif as dit byt of steek?

Its tentacles carry nematocysts, tiny coiled, thread-like stingers that inject venom on contact. The venom can paralyse small fish and other prey. The sting is powerful enough to kill fish, crustaceans and, in some cases, humans.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: Ernstig'n Steek moet deur 'n dokter gesien word. Sterftes is baie skaars.

Its stings are painful and it is well known to beachgoers. In some cases the sting can kill humans. Large groups can also reduce fish populations and damage fishing supplies.1

Wat doen dit as dit bang is?

When attacked at the surface, it can deflate its pneumatophore and temporarily submerge.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

It is not a single animal. It is a colony of zooids, all genetically identical, that work together like organs in one body.1

The blanket octopus is immune to its venom and uses broken tentacles as weapons.1

Its float can produce carbon monoxide, which makes up as much as 13% of the gas inside it.1

The loggerhead sea turtle eats it regularly, because its thick skin protects it from the stings.1

The man-of-war fish can live among its tentacles and feeds on them, while avoiding being stung.1

Mite-breker

Mite: It is a jellyfish.

Waarheid: It only looks like a jellyfish. It is a siphonophore, a colony of many linked zooids.1
