Kangaude wamchira: kuyambira zotsalira zakale mpaka ma arachnids amakono
akangaude ndi mbali yofunika kwambiri ya chilengedwe. Amagwira ntchito yofunika kwambiri - amadya tizilombo tosiyanasiyana ndipo potero amathandiza wamaluwa ndi wamaluwa. Mitundu yonse ya akangaude imakhala ndi mawonekedwe ofanana. Koma asayansi apeza anthu achilendo omwe anali ndi michira.
Kapangidwe ka akangaude
Akangaude ali ndi mawonekedwe apadera omwe amawasiyanitsa ndi ma arachnids ena:
- cephalothorax ikuwonjezeka;
Akangaude: mawonekedwe akunja.
- mimba ndi yotakata;
- nsagwada zopindika - chelicerae;
- mahema a phazi - ziwalo za kukhudza;
- miyendo 4 pawiri;
- thupi lakutidwa ndi chitin.
Akangaude okhala ndi michira
Iwo omwe amatchedwa akangaude amchira alidi oimira arachnids, omwe amakhala kumadera otentha. Amatchedwa Telifons - nyama zopanda poizoni, arthropods, zomwe zimafanana ndi akangaude ndi zinkhanira.
Nyama zokhala ndi ndondomeko kumbuyo, zomwe zimakhala zofanana ndi mchira, zimakhala m'madera otchedwa Dziko Latsopano komanso mbali zina za Pacific. Izi:
- kum'mwera kwa USA;
- Brazil;
- New Guinea;
- Indonesia;
- kum'mwera kwa Japan;
- Eastern China.
Oimira a Telifona subspecies ndi aakulu kwambiri, kuyambira 2,5 mpaka 8 cm muutali. Mapangidwe awo ndi ofanana ndi mitundu wamba ya akangaude, koma gawo loyamba la pamimba limachepetsedwa, ndipo njirayi ndi mtundu wa chiwalo chokhudza.
Mitundu yosowa kwambiri imeneyi imaberekana ndi umuna wakunja. Azimayi ndi amayi osamala, amakhala mu mink mpaka ana akuwonekera. Amakhala pamimba mwa mayi okha mpaka molt woyamba.
akangaude akale amchira
Zotsalira za akale mchira wa akangaude.
Asayansi ochokera ku India apeza m’mabwinja a kangaude amene anakhalako zaka zoposa 100 miliyoni zapitazo. Awa ndi ma arachnids omwe anali ndi kangaude ndipo amatha kuluka silika. Ankakhulupirira kuti mitundu ya Uraraneida inazimiririka kuyambira nthawi ya Paleozoic.
Akangaude omwe amapezeka m'mabwinja a amber ochokera ku Burma, ndipo amatha kutchedwa kuti, anali ofanana ndi arachnids omwe amakhala masiku ano, koma anali ndi maulendo aatali, omwe kukula kwake kumaposa ngakhale kutalika kwa thupi.
Asayansi adatcha mtundu uwu Chimerarachne. Iwo anakhala mgwirizano wosintha pakati pa akangaude amakono ndi makolo awo. Zambiri zolondola za woimira mitundu ya Chimerarachne sizinasungidwe. Njira ya caudal inali chiwalo chomva bwino chomwe chinagwira kugwedezeka kwa mpweya ndi zoopsa zosiyanasiyana.
Pomaliza
Akangaude amchira amasiku ano amaimiridwa ndi zitsanzo zochepa chabe. Ndipo ma caudal awo alibe njerewere za arachnoid. Ndipo oimira akale anali akangaude omwewo, okhala ndi chiwalo chowonjezera chokhudza - mchira wautali.
