Amandla etyhefu yokuluma nokuhlaba

Siyafafaza okanye sitshica

Sifafaza okanye sitshica ulwelo oluhlabayo kwabo basihlaselayo.

Ityhefu yaso yokuluma okanye yokuhlaba yenza ntoni?

Its venom is mostly cytotoxic, meaning it destroys cells, and it also has typical elapid neurotoxic (nerve-attacking) effects and cardiotoxic (heart-damaging) components. A bite causes severe bleeding from the wound, tissue death around the bite, and difficulty breathing. Venom in the eyes causes extreme burning pain, loss of coordination, partial loss of vision, and permanent blindness.1

Its venom is medically significant. The death rate for untreated bites is about 5 to 10%, and under 1% in areas where it is common. When death occurs, it is usually from paralysis of the diaphragm, the muscle used for breathing.1

Senza ntoni xa soyika?

It spits venom from its fangs at a threat, reaching up to 7 metres with good accuracy. It also bites readily, even with only slight provocation.1

Ukuba siyaluma okanye sitshica

  • If venom gets into the eyes, it should be washed off, because permanent blindness can follow if it is not. Anyone bitten should get medical treatment, as untreated bites carry a much higher risk of death.1
  • Gcina umntu engashukumi kwaye ezolile, susa imisesane nezinto eziqinileyo, uze umse esibhedlele ngokukhawuleza: i-antivenom lunyango.
  • Ukuba ityhefu itshicelwe emehlweni, wahlambulule ngamanzi amaninzi acocekileyo ngoko nangoko.

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 okanye sitshica ityhefu emehlweni akho: 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

1

It can spit venom accurately more than 7 metres away.1

2

In 1944, a British eye surgeon, Major Harold Ridley, described eye damage from a spit from this cobra in Ghana. He treated the man and followed his case until the eye fully recovered.1

3

A single bite can deliver 200 to 350 mg of venom (dry weight), according to a 1974 study by Minton.1

4

It is an excellent tree climber and can live in trees at times.1

5

Wild-caught individuals tend to be nervous and spit readily, while captive-bred animals are much calmer.1

6

It can be active at night or during the day, depending on the season, location and temperature.1

Umqhekezi weentsomi
