The radiant sea urchin is a large, colourful sea urchin with long, spiky spines. It lives in warm, shallow seas across the Indo-Pacific, from the African coast to Hawaii and Australia. Its spines are venomous, so it is one to admire from a distance.1

Kako jo prepoznaš

A large urchin, with a body (test) up to 20 cm across.1
Long, hollow spines up to 4 cm, in five vertical clusters.1
Between the clusters are bare, V-shaped red areas with lines of iridescent blue dots.1
The rest of the body and spines range from reddish brown to purple, dark brown or nearly black.1
Juveniles have spines with banding across them, and this sometimes stays into adulthood.1

Moč strupa

Strupene bodice

Ostre bodice nosijo strup. Če stopiš nanjo ali jo primeš, boli.

Kaj naredi njen strup, ko ugrizne ali piči?

Its spines are venomous and can cause painful wounds. The spines are long and hollow, and the shorter of the two kinds are the venomous ones.1

Kako nevarna je za ljudi?

Nevarnost za ljudi: BolečeLahko zelo boli, a skoraj nikoli ni resno.

It is not deadly to humans, but its spines can cause painful wounds. Because it is large and brightly coloured, divers can usually see it, so injuries from stepping on one are fairly rare. On the 'Kings of Pain' pain index it scores 12 out of 30.1

Kaj naredi, ko se prestraši?

It is sensitive to light and can angle its spines towards an approaching threat.1

Če te zbode z bodicami

Rano daj v vročo vodo, tako vročo, kot jo poškodovanec prenese, ne da bi se opekel, in poišči zdravniško pomoč, da odstranijo bodice. Ne izkopavaj jih sam.

Vedno najprej pokliči številko za klic v sili (112, 000, 911). To so splošna navodila za prvo pomoč, ne zdravniški nasvet. Osnove prve pomoči

Ostani varen

Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
Če te zbode z bodicami: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti

Dejstva

A crab called Dorippe frascone carries the urchin on its back.1

Several shrimps, crabs and small fish live among its spines for shelter.1

Its scientific name refers to a star-shaped pattern around its anus, not to the animal's shape as a whole.1

Its bright colours and size make it a favourite subject for underwater photographers and some expert fish-keepers.1

Its young larvae drift in the ocean as plankton before they settle on the seabed.1
