Amandla etyhefu yokuluma nokuhlaba

Amava anetyhefu

Amava abukhali aphethe ityhefu. Ukusinyathela okanye ukusibamba kubuhlungu.

Ityhefu yaso yokuluma okanye yokuhlaba yenza ntoni?

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

Siyingozi kangakanani ebantwini?

Ingozi ebantwini: KubuhlunguKunokuba buhlungu ngokwenene, kodwa phantse akusoze kube kubi kakhulu.

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

Senza ntoni xa soyika?

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

Ukuba amava aso ayakugwaza

Faka inxeba emanzini ashushu, ashushu kangangoko umntu angakwazi ukunyamezela ngaphandle kokutshiswa, kwaye ufumane uncedo lwezonyango ukuze kususwe amava. Musa ukuwemba ngokwakho.

Soloko utsalela inombolo kaxakeka kuqala (112, 000, 911). Esi sisikhokelo soncedo lokuqala ngokubanzi, asilocebiso lwezonyango. Iziseko zoncedo lokuqala

Hlala ukhuselekile

Ungaze uchukumise, ubambe okanye uqhule isilwanyana sasendle, nokuba sincinci, kwaye nokuba sibonakala silele okanye sifile.
Sinike indawo. Ukuba udibana naso, hlala uzolile, buyela umva kancinci kwaye usiyeke sihambe ngendlela yaso.
Ukuba amava aso ayakugwaza: hlala uzolile, musa ukushukuma, tsalela inombolo kaxakeka (112, 000, 911) okanye uye esibhedlele ngokukhawuleza. Khumbula ukuba sasikhangeleka njani, ifoto iyanceda.

Asikuzingeli. Sisebenzisa ityhefu yaso ukubamba ukutya okanye ukuzikhusela, kwaye singakhetha ukuzimela. Okungakumbi malunga nokuhlala ukhuselekile

kufanelekile ukwazi

Iinyaniso

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
