Otrovna snaga

Ubodi

Otrov izlazi kroz žalac.

Što radi njegov otrov kad ugrize ili ubode?

Its venom is made in glands at the base of the flower-like claws, not in the spines. The claws have sharp fang-like tips that can penetrate human skin, and when touched they snap shut and inject venom. The sting is described as extremely painful and medically significant.1

Koliko je opasno za ljude?

Opasnost za ljude: Vrlo opasnoMože ubiti osobu koja ne dobije liječenje.

It is considered highly dangerous to people. Its stings are extremely painful and medically significant. Larger individuals with bigger claws are thought to be more dangerous, because the strength of the venom is linked to claw size.1

Što radi kad se uplaši?

When touched or brushed against, its flower-like claws snap shut and inject venom. The claws can break off and stay attached to the skin, continuing to inject venom for several hours.1

Ako ubode

Stavi ranu u vruću vodu, toliko vruću koliko osoba može podnijeti bez opeklina, i potraži liječničku pomoć za vađenje bodlji. Ne pokušavaj ih iskopati.

Ostani na sigurnom

Nikad ne diraj, ne hvataj i ne zadirkuj divlju životinju, čak ni malu, i čak ni ako izgleda kao da spava ili je mrtva.
Ostavi joj prostora. Ako je sretneš, ne paniči, polako se odmakni i pusti je da ode svojim putem.
Ako te neka ubode: ne paniči, miruj, nazovi broj za hitne slučajeve (112, 000, 911) ili brzo idi u bolnicu. Zapamti kako je izgledala, fotografija pomaže.

Ne želi ti ništa loše. Otrov koristi za lov hrane ili za obranu i mnogo bi se radije sakrilo. Više o sigurnosti

Činjenice

Unlike most venomous sea urchins, it does not sting through its spines. Its venom is delivered through the claws.1

A zebra crab, Zebrida adamsii, often lives attached to its shell. The crab is thought to be immune to its venom.1

Its flower-like claws are the source of its common name and are its most striking feature.1

Tiny shrimp, Athanas areteformis, sometimes live among its spines.1

In the seashell trade, its empty shells are called "mushroom urchins" because they look like mushroom caps.1
