As dit byt

Was die byt en sit 'n yspak daarop vir die pyn. Kry mediese hulp as die pyn erg is, versprei of die persoon sleg voel.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou byt: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

After mating, the male may escape being eaten by living in the nest with the female for a time, but in other cases the female eats him.1

Its web has separate areas for nesting and for catching prey, and it also helps keep the spider cool by providing shade in summer.1

Its webs often include a funnel of silk decorated with debris, which may help hide the spider from predators such as birds flying overhead.1

The web's silk carries pheromones that help males find female nests.1

Its colour darkens after each moult, so the spider becomes darker as it grows older.1
