The night anemone is a sea anemone, a soft animal related to jellyfish that attaches itself to the seabed. It lives in shallow seas in the central Indo-West Pacific, including Indonesia, the Philippines and southern Japan. It is venomous, and its sting can cause a painful injury that lasts a long time.1

Tuis

It lives in shallow seas and attaches to the seabed by a broad base. Divers and swimmers may meet it in these shallow waters.1

Wat eet dit?

At night its oral disc opens and its tentacles spread out to catch zooplankton and small invertebrates.1

Hoe om dit te herken

Has a broad base that attaches it to the seabed.1
Has branching, stalked outgrowths called pseudo-tentacles, which vary a lot between individuals.1
Some individuals look like smooth discs, branching coral, or dead coral rock covered in algae.1
The mouth ring has up to 160 long tentacles, seen when it is feeding at night.1

Word dikwels verwar met: It is often mistaken for corals, algae or dead coral rock, because it copies their shape and colour. During the day it pulls its mouth and tentacles inside, so it may not look like a sea anemone at all.1

Gifkrag

Steektentakels

Duisende piepklein steekselle skiet af wanneer iets aan hulle raak.

Wat doen sy gif as dit byt of steek?

Its venom contains several haemolytic toxins, which break down red blood cells. Human contact can cause severe dermatitis, with swelling and ulceration of the affected skin that may last for months. On rare occasions it causes acute kidney damage, and it is the first sea anemone whose venom has been shown to do this. The venom does not appear to affect other major organs.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: Baie gevaarlikDit kan 'n mens doodmaak wat geen behandeling kry nie.

Its sting is painful and long-lasting. On rare occasions it can cause acute kidney damage.1

Wat doen dit as dit bang is?

It uses camouflage, mimicry and masquerade to blend into its surroundings, which helps it deceive prey and confuse predators.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 was the first sea anemone found to have venom that damages the kidneys and can cause acute renal failure.1

Its venom kills shrimp and breaks down sheep red blood cells in laboratory tests.1

Its pseudo-tentacles contain symbiotic dinoflagellates, tiny organisms that photosynthesise, so it gets some energy from light.1

It hides its tentacles and mouth during the day, when it spreads out its pseudo-tentacles to catch sunlight.1
