Ama-arachnids amakhizane, izicabucabu, ama-scorpions
Kunamakhulu ezinkulungwane zezilwane ezehlukene endalweni. Kodwa ama-arachnid ethusa abaningi. Nakuba phakathi komndeni omkhulu kukhona labo abangalimazi abantu, kodwa kukhona nabameleli abayingozi.
Okuqukethwe
Obani ama-arachnids
Ama-arachnids umndeni omkhulu wama-arthropods. Manje kunezinhlobo ezingaphezu kuka-114000. Ngokwengxenye enkulu, zonke ziyizilwane ezidla ezinye ezihlala phansi, nakuba kukhona okuhlukile.
Ama-Arachnids.
Ama-arachnids ahlanganisa:
- ofezela;
- izicabucabu;
- imikhaza.
Ukwakheka kwama-arachnids
Izinhlobo ezahlukene zinosayizi abahlukene kakhulu. Ezincane kakhulu ezinye izibungu, zingafinyelela ubude ikhulu microns. Abaholi ngosayizi bangama-tarantula nama-solpugs.
Inezingxenye ezimbili eziyinhloko, i-cephalothorax nesisu. Awekho amadevu.
Izilwane zihamba ngamapheya angu-4 emilenze. Anama-chelicerae kanye nama-pedipalps, asiza ukubamba nokubamba inyamazane.
Umzimba wama-arachnids umbozwe nge-cuticle encane kodwa eminyene ye-chitinous.
Ezinhlotsheni ezahlukene, izitho zokuphefumula zingaba izinhlobo ezimbili: i-trachea namasaka wamaphaphu. Inqwaba yemikhaza emincane ayinazo izitho ezikhethekile; ukushintshana kwenzeka ebusweni bomzimba.
Yonke imithambo yegazi inezindonga zayo. I-circulatory system ayivaliwe, isitho esiyinhloko yinhliziyo.
Kukhona uchungechunge lwezinzwa zesisu ezihlelekile, izingxenye zangaphambili nezingemuva zobuchopho.
Izinwele zithe chithi saka emzimbeni wesicabucabu, okusebenza njengama-transmitter asabela ekundindizeleni futhi adlulise ukwaziswa.
Ama-arachnids angaba namehlo ama-2 kuye kwayi-12. Zitholakala ku-cephalothorax futhi zithatha ukudlidliza komoya ezinhlangothini, hhayi nje ngaphambili.
Ezicabungwini, ukugaya ngokwengxenye kuphuma emathunjini. Bajova ushevu kulowo ohlukunyeziwe, bawenze uketshezi oluncane, bese bewuphuza.
Ngokuya ngezinhlobo, ama-arachnids abeka amaqanda, iningi lawo. Kodwa abanye ofezela nababelethi bezilwane.
Ukusabalalisa nokubaluleka kwabameleli
Ama-arachnids atholakala yonke indawo futhi enza imisebenzi eminingi ehlukene.
Inani lama-arachnids emvelweni nakubantu
Zonke izidalwa eziphilayo zinendima yazo. Ama-arachnids ayingxenye yochungechunge lokudla. Bona ngokwabo badla izinambuzane ezincane, ngokuvamile zisiza abantu ekulweni nezinambuzane.
Amalungu omndeni ngokwawo nawo abe ukudla kubantu abakhulu bohlobo lwayo, ama-arthropods, izilwane ezihlala emanzini nasezweni nezilwane ezihlukahlukene.
Ezinye izitha zomuntu:
- izicabucabu ziyaluma, zibangele ubuhlungu kanye nemiphumela emibi nakakhulu;
- imikhaza ithwala izifo ezihlukahlukene;
- ofezela bakhetha ukungabathinti abantu futhi bahlale ngokwehlukana, kodwa uma bengena endaweni yokuhlala noma ezintweni, balume kabuhlungu kakhulu.
isiphetho
Umndeni we-arachnid mkhulu kakhulu. Phakathi kwazo kunezilwane eziwusizo neziyingozi. Izinhlobo ezahlukene zinendlela yazo yokuphila, kusukela ezilwaneni ezizingelayo kuye kuma-parasite. Kodwa zonke zinendima yazo endalweni.
