Hufanya nini akiogopa?

To escape birds, it can fully submerge itself in water and has been known to hide underwater for several minutes.1

Akiuma

Osha jeraha na uweke barafu kupunguza maumivu. Tafuta msaada wa kitabibu kama maumivu ni makali, yanasambaa au mtu anajisikia vibaya.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Akikuuma: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

Ukweli

This spider is one of the few species known to attack nearly almost all approaching males, which biologists consider unusual because it can stop mating from succeeding.1

The raft spider can stay hidden underwater for several minutes.1

Females will sometimes eat the male before, during or immediately after mating.1

Males signal their presence to the female by using vibrations on her dragline, which may help them avoid being attacked.1
