Kung matusok ka ng mga tinik nito

Ilubog ang sugat sa mainit na tubig, kasing-init ng kayang tiisin ng tao nang hindi napapaso, at kumuha ng tulong medikal para maalis ang mga tinik. Huwag mo itong hukayin nang mag-isa.

Laging tawagan muna ang numero pang-emergency (112, 000, 911). Ito ay pangkalahatang gabay sa pangunang lunas, hindi payong medikal. Mga batayan ng pangunang lunas

Mag-ingat

Huwag kailanman hawakan, hulihin o asarin ang ligaw na hayop, kahit maliit, at kahit mukha itong tulog o patay.
Bigyan ito ng espasyo. Kung makasalubong ka ng isa, manatiling kalmado, dahan-dahang umatras at hayaan itong umalis.
Kung matusok ka ng mga tinik nito: manatiling kalmado, huwag gumalaw, tawagan ang numero pang-emergency (112, 000, 911) o pumunta agad sa ospital. Tandaan ang itsura nito, makakatulong ang litrato.

Hindi ka nito hinahabol. Ginagamit nito ang kamandag para manghuli ng pagkain o ipagtanggol ang sarili, at mas gusto pa nitong magtago. Higit pa tungkol sa pag-iingat

Mga fact

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
