Siyingozi kangakanani ebantwini?

Uma siluma

Ezinweleni zezimbungu ezihlabayo: zisuse ngetheyiphu enamathelayo, bese ugeza isikhumba. Ungahlikihli.
Uma kulunyiwe: geza bese upholisa. Thola usizo lwezokwelapha uma umuntu ezizwa engaphilile noma opha kalula.

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

It breathes air but has no gills. It keeps a thin film of air around its body, which can last up to 120 days.1

It can tell prey from other backswimmers by the surface waves they make. Prey waves are between 70 and 140 Hz, while other backswimmers make waves below 40 Hz.1

Its air film reduces drag when it dives. Scientists use it as a model for reducing drag, with possible uses such as on ships.1

It can see in both day and night. Its pupil takes about 40 minutes to adjust to daylight and about 50 minutes to adjust to night light.1
