Flower urchin
The flower urchin is a sea urchin with flower-shaped claws that can sting. It lives on coral reefs, in seagrass beds and on rocky or sandy sea floors across the Indo-West Pacific. It is one of the sea urchins most likely to cause a painful and medically significant sting.1

Ziztatzen badu
- Sartu zauria ur beroan, pertsonak erre gabe jasan dezakeen bezain beroan, eta lortu mediku-laguntza arantzak kentzeko. Ez saiatu zuk zeuk ateratzen.

Egon seguru
- Ez ukitu, ez harrapatu eta ez zirikatu inoiz animalia basati bat, txikia izan arren, eta lo edo hilda dagoela badirudi ere.
- Utzi tartea. Bat aurkitzen baduzu, egon lasai, egin atzera poliki eta utzi bere bidetik joaten.
- Batek ziztatzen bazaitu: egon lasai, egon geldi, deitu zure larrialdi-zenbakira (112, 000, 911) edo joan ospitalera azkar. Gogoratu nolakoa zen, argazki batek laguntzen du.
Ez dabil zure atzetik. Pozoia janaria harrapatzeko edo bere burua babesteko erabiltzen du, eta askoz nahiago du ezkutatu. Seguru egoteari buruz gehiago
