Ukuba siyaluma

Hlamba indawo elunyiweyo uze ubeke ipakethi yomkhenkce kuyo ngenxa yeentlungu. Fumana uncedo lwezonyango ukuba iintlungu zinamandla, ziyasasazeka okanye umntu uziva engaphilanga kakuhle.

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 siyakuluma: 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

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
