Banded sea urchin
Amava anetyhefuThe banded sea urchin is a spiny sea animal that lives on tropical reefs and in lagoons across the Indo-Pacific. It is active at night and hides in cracks or under rocks during the day. Its thin spines can deliver a sting, although the sting is not dangerous.1

Indlela yokusiqaphela
- It has a slightly oval shell (test) about 5 cm across.1
- It has two kinds of spines: short, slender spines that run from yellow to dark, and longer, thicker spines that are often banded with light and dark colour.1
- The longer spines reach 10 to 15 cm and can be blunt and hollow.1
- Five bare zones in a star pattern show on the middle of the shell, and these can look blue.1
Sidla ngokubhidaniswa no: Dark forms can look like Diadema setosum or Diadema savignyi. Diadema savignyi is bigger, more uniformly black, and has five white spots on top of its shell and an orange ring around its anus. The most common mix-up is Echinothrix diadema, which can have banded spines when young. Echinothrix diadema has a very small, all-black anal papilla and blue-sheened spines, and its spines do not crush easily, unlike the spines of the banded sea urchin.1
Amandla etyhefu yokuluma nokuhlaba
Amava abukhali aphethe ityhefu. Ukusinyathela okanye ukusibamba kubuhlungu.
Ityhefu yaso yokuluma okanye yokuhlaba yenza ntoni?
The thinner, short spines are venomous, meaning they deliver venom through a sting. The sting is nasty, but the venom is not dangerous.1
Siyingozi kangakanani ebantwini?
Ingozi ebantwini: KubuhlunguKunokuba buhlungu ngokwenene, kodwa phantse akusoze kube kubi kakhulu.The thinner spines are venomous but not dangerous.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

Iinyaniso
Its anal papilla is large and whitish with black and white dots, and a ring of visual receptors around it gives it basic vision.1
Young cardinal fish from the family Apogonidae often hide among the spines for protection.1
In Hawaii, this sea urchin often carries a symbiotic crab, Echinoecus pentagonus, that lives with it.1
It is active at night and spends the day hidden in crevices or under rocks.1
