Izicabucabu ezinamaphiko noma ukuthi ama-arachnid andiza kanjani

Umlando omncane

Ohambweni lwakhe olulandelayo nge-Her Majesty's Beagle, uCharles Darwin wathola izicabucabu. Futhi lokhu ngeke kube okungajwayelekile, uma kungenjalo ngezimo ezimbalwa:

1. Umkhumbi wawuhamba amakhilomitha angamakhulu ukusuka ogwini.
2. Umkhumbi wawusolwandle isikhathi eside kakhulu.
3. Isiqhingi esikude ePacific sase sisondela.

Yiqiniso, usosayensi wayenesithakazelo endleleni lezi zicabucabu ezincane ezifika ngayo emkhunjini. Futhi kwakukhona abameleli bohlobo eziqhingini zeziqhingi zaseJuan Fernandez.

izicabucabu ezindizayo

Isicabucabu sesipoki.

Izicabucabu ezindizayo noma ezindizayo zibiza bonke abameleli abakwazi ukuhamba "emoyeni." Muva nje bahlolisiswe futhi benziwa uhlobo oluhlukile - i-Philisca ingens kanye nezipoki eziteketiswa.

Lezi zidalwa ezincane, ezifika ku-25 mm ngobukhulu. Umzimba mkhulu, futhi imilenze ilula futhi ayibonakali. Laba bantu batholakala naseRussia, kwezinye izindawo emzileni ophakathi naseMpumalanga Ekude.

Kuyathakazelisa ukuthi abameleli bohlobo olufanayo lwamaflaya bahluke komunye nomunye ngokuma nesakhiwo somzimba. Lokhu kusebenza kubantu abangabodwa nabahlala ezwenikazi.

Zindiza kanjani izicabucabu

Abacwaningi bembula imfihlakalo yokuthi izicabucabu zindiza kanjani. Ngaphezu kwezindlela ezaziwa kakhulu zokunyakaza ku-cobwebs, ezisetshenziswa izinhlobo eziningi zezicabucabu, elinye ikhono selivele.

Izinhlobo zezicabucabu, ezibizwa ngokuthi izipoki, ziyakwazi ukusebenzisa amaza omoya ngisho namandla kazibuthe omhlaba ukuhambahamba. Yiqiniso, abakwazi ukulawula i-trajectory ngokunemba kwamasentimitha amaningana, kodwa babeka isiqondiso ngokwabo.

Isistimu yendiza ngosizo lwezindleko zikagesi ihlolwe futhi ngempumelelo esetshenziswa ama-bumblebees.

Izicabucabu ze-Selenops

I-Selenops banksi ibhekwa njengesicabucabu esizungezayo. Lezi yizilwane ezihlala ehlathini lemvula lase-Amazon. Bahlala phezulu kwezihlahla. Lolu hlobo lwesicabucabu luyisilwane esisheshayo futhi esinamandla.

Izicabucabu zezinhlobo ze-Selenops, ukuze zizivikele futhi zisheshise ukuzingela, zafunda ukuhlela phakathi kwezihlahla. Okwamanje, ososayensi abavela eNyuvesi yaseCalifornia eBerkeley basaqhuba ucwaningo.

Amabhange e-Selenops.

Kodwa umkhuba ubonise ukuthi lezi zicabucabu zisebenzisa ama-air currents ukuze zizuze:

1. Izicabucabu zokuhlola zanyakaziswa ukusuka phezulu.
2. Babheke phansi.
3. Bendlala izidladla zabo emaceleni.
4. Iqondiswa ngobumnene endizeni.
5. Azikho izicabucabu ezawa njengetshe.

isiphetho

Uma izicabucabu zingandiza, khona-ke wonke umuntu ophethwe yi-archaphobia uzosaba ukuphuma endlini. Ngenhlanhla, izicabucabu eziyizipoki ezithole ikhono lokuzulazula ngosizo lwensimu kazibuthe namawebhu zincane kakhulu futhi azilimazi abantu.
