Amandla obuthi

Ukuluma

Ubuthi buphuma ngamazinyo aso obuthi noma ngamazinyo uma siluma.

Siyingozi kangakanani ebantwini?

Ingozi ebantwini: KuncaneNjengokuhlatshwa yinyosi noma ngaphansi. Cishe akunangozi ebantwini.

Bites are not considered dangerous to humans or pets.1

Uma siluma

  • Geza inxeba lokulunywa bese ubeka iphakethe leqhwa phezu kwalo ngenxa yobuhlungu. Thola usizo lwezokwelapha uma ubuhlungu bunamandla, busabalala noma umuntu ezizwa engaphilile.

Njalo shayela kuqala inombolo yezimo eziphuthumayo (112, 000, 911). Lokhu kuyiseluleko sosizo lokuqala esijwayelekile, akusona iseluleko sezokwelapha. Izisekelo zosizo lokuqala

Hlala uphephile

  • Ungalokothi uthinte, ubambe noma ugcone isilwane sasendle, ngisho noma sincane, futhi ngisho noma sibukeka silele noma sifile.
  • Sinike isikhala. Uma uhlangana naso, hlala uzolile, uhlehle kancane bese usiyeka sihambe ngendlela yaso.
  • Uma sikuluma: hlala uzolile, ungashukumi, shayela inombolo yezimo eziphuthumayo (112, 000, 911) noma uye esibhedlela ngokushesha. Khumbula ukuthi besibukeka kanjani, isithombe siyasiza.

Asikuzingeli wena. Sisebenzisa ubuthi baso ukuze sibambe ukudla noma ukuzivikela, futhi singancamela ukucasha. Okwengeziwe mayelana nokuhlala uphephile

Amaqiniso

1

The eyes are all the same size and sit in two rows. They contain few visual cells, so the spider can probably only tell light from dark.1

2

Until 2018, the giant house spider was treated as one species. Research then showed three separate species, which can only be told apart under a microscope.1

3

Males wander while searching for females during mating season, which runs from late summer into autumn. This is when they are most often noticed.1

4

Males have no Y chromosome. Males carry X1 and X2, and females carry two pairs of X chromosomes. This form of sex determination is the most common in spiders and is probably the ancestral form.1
