Chifukwa cha mawonekedwe awo ndi mbiri yosalungama, tarantula lero ndi imodzi mwazinyama zokanidwa kwambiri, zoopedwa komanso zoperekedwa nsembe; komabe, kwenikweni ndi nyama zopanda chitetezo komanso zamanyazi zomwe zakhala padziko lapansi kuyambira nthawi ya Carboniferous ya nthawi ya Paleozoic, pafupifupi zaka 265 miliyoni zapitazo.
Ogwira ntchito ku Unam Acarology Laboratory atha kutsimikizira kuti palibe zolemba zamankhwala, kuyambira koyambirira kwa zaka zapitazo, zomwe zimalemba zaimfa ya munthu ndi kuluma kwa tarantula kapena yolumikiza nyama yamtunduwu ndi ngozi yakupha. Zizolowezi za tarantula nthawi zambiri zimakhala usiku, ndiye kuti, amapita usiku kukasaka nyama yawo, yomwe imatha kukhala kuchokera ku tizilombo tating'onoting'ono, monga crickets, kafadala ndi nyongolotsi, kapenanso makoswe ang'onoang'ono ngakhale anapiye ang'onoang'ono omwe amawagwira molunjika kuzisa. Chifukwa chake, limodzi la mayina odziwika omwe amapatsidwa ndi "kangaude wa nkhuku".
Tarantulas ndi nyama zokhazokha zomwe zimakhala zobisika tsiku lonse, pokhapokha nthawi yokwanira kumakhala kotheka kupeza yamphongo yomwe ikuyenda masana kufunafuna yaikazi, yomwe imatha kutetezedwa mu dzenje, khungwa kapena dzenje la mtengo, kapena ngakhale pakati pa masamba a chomera chachikulu. Mwamuna amakhala ndi moyo, ngati wamkulu, wazaka pafupifupi chimodzi ndi theka, koma wamkazi amatha kufikira zaka makumi awiri ndipo amatenga zaka zisanu ndi zitatu mpaka khumi ndi ziwiri kuti akhwime. Ichi chitha kukhala chimodzi mwazifukwa zazikulu zomwe zimatipangitsa kulingalira kawiri tisanapereke nsapato zachikale ku tarantula, chifukwa m'masekondi ochepa titha kukhala ndi cholengedwa chomwe chimatenga zaka zambiri kuti chikhale chosunga mitundu yake.
Kukhathamira kumakhala ndi kulimbana koopsa pakati pa banjali, momwe mwamuna amayenera kuyika mkaziyo patali mokwanira pogwiritsa ntchito zomangirira miyendo yakutsogolo, yotchedwa zingwe za tibial, kuti asadye, komanso nthawi yomweyo Kufikika kwake ndikutsegulira kwake kwa maliseche, kotchedwa epiginium, yomwe ili kumunsi kwa thupi lake, mu mpira wawukulu, wakumbuyo, kapena opistosoma. Kumeneko wamwamuna amakayika umuna pogwiritsa ntchito nsonga yake pomwe chiwalo chake chogonana chotchedwa babu ndi. Umuna ukayika m'thupi la mkazi, umasungidwa mpaka chilimwe chotsatira, ukadzatuluka ku hibernation ndikufunafuna malo oyenera kuyamba kukolopa ovisco komwe ungayikemo mazirawo.
Makulidwe a moyo amayamba mzimayi akaika ovisac, pomwe mazira 600 mpaka 1000 amaswa, 60% okha ndi omwe amakhala ndi moyo. Amadutsa magawo atatu amakulidwe, nymph, pre-wamkulu kapena mwana, komanso wamkulu. Akakhala nymphs amayamba kusungunuka khungu lawo lonse kawiri pachaka, ndipo akamakula kamodzi pachaka. Amuna nthawi zambiri amamwalira asanakule ngati achikulire. Khungu lomwe amasiya limatchedwa exuvia ndipo ndi lokwanira komanso labwino kotero kuti arachnologists (entomologists) amawagwiritsa ntchito kuzindikira mtundu womwe wasintha. Akangaude onse akuluakulu, aubweya komanso olemera amakhala m'magulu a Theraphosidae , ndipo ku Mexico mumakhala mitundu 111 ya ma tarantula, omwe ambiri mwa iwo ndi aphonopelma ndi brachypelma. Amagawidwa ku Republic of Mexico, pokhala ochuluka kwambiri m'malo otentha ndi achipululu.
Ndikofunika kudziwa kuti akangaude onse a mtundu wa brachypelma amaonedwa kuti ali pangozi yakutha, ndipo mwina izi ndichifukwa choti ndiwowoneka bwino kwambiri chifukwa cha mitundu yawo yosiyanitsa, zomwe zimawapangitsa kukhala osakondera ngati "ziweto". Kuphatikiza apo kupezeka kwake kumunda kumawonekeratu mosavuta ndi adani ake, monga ma weasel, mbalame, makoswe komanso makamaka mavu Pepsis sp. yomwe imayikira mazira ake mthupi la tarantula, kapena nyerere, zomwe zimawopseza kwambiri mazira kapena ma tarantula obadwa kumene. Njira zodzitchinjiriza za ma arachnid awa ndizochepa; mwina chothandiza kwambiri ndikuluma kwake, komwe chifukwa cha kukula kwa mano ake kumakhala kowawa; Amatsatiridwa ndi tsitsi lomwe limaphimba kumtunda kwa mimba ndipo limakhala ndi malo oluma: ikakhala pakona, ma tarantula amawaponyera kwa omwe akuwaukira ndi ma rubs ofulumira komanso obwereza, kuphatikiza powagwiritsa ntchito kuphimba makoma olowera kukhoma kwawo, momveka bwino zifukwa zodzitchinjiriza; Pomaliza, pali mawonekedwe owopseza omwe amatenga, akukweza kutsogolo kwa matupi awo kuti awulule zoyipa zawo ndi chelicerae.
Ngakhale ali ndi maso asanu ndi atatu, osanjidwa mosiyanasiyana kutengera mitundu yomwe ikufunsidwayo - koma onse omwe ali kumtunda kwa chifuwa--, ali akhungu, amayankha m'malo ang'onoang'ono a nthaka kuti agwire chakudya chawo, ndi Thupi lokutidwa kwathunthu ndi minofu yaubweya limatha kumva kupumira pang'ono kwa mpweya, motero kumawakwaniritsa masomphenya omwe kulibe. Monga pafupifupi akangaude onse, amalukanso mawebusayiti, koma osati chifukwa cha kusaka koma chifukwa chofuna kubereka, popeza ndipamene amuna amatulutsa umuna kenako, mwa mphamvu, amalowetsa mu babu, ndipo wamkazi amapanga ovisaco ndi ndodo. Zonsezi zimaphimba mzere wawo wonse ndi nthiti kuti zikhale bwino.
Mawu oti "tarantula" amachokera ku Taranto, Italy, komwe kangaude Lycosa tarentula amachokera, kachilombo kakang'ono kamene kali ndi mbiri yoopsa ku Europe konse m'zaka za m'ma 1400 mpaka 1700. Ogonjetsa a ku Spain atafika ku America ndipo anakumana ndi otsutsa akuluakulu, owopsa, nthawi yomweyo adawafotokozera ku tarantula yoyambirira yaku Italiya, motero kuwapatsa dzina lawo lomwe tsopano ladziwika padziko lonse lapansi. Monga odyetsa ndi odyetsa, tarantula ali ndi malo osasunthika m'malo awo, popeza amayang'anira bwino kuchuluka kwa nyama zomwe zitha kukhala tizirombo, ndipo ndizo chakudya cha mitundu ina yomwe ndiyofunikanso kuti moyo upitirire. Pachifukwa ichi, tiyenera kuzindikira za nyama izi ndikumbukira kuti "sizoweta" ndikuti kuwonongeka komwe timachita pa chilengedwe ndi kwakukulu ndipo mwina sikungakonzeke tikazipha kapena kuzichotsa m'malo awo achilengedwe. M'mizinda ina ku United States, ntchito yapezeka kwa iwo, kuphatikiza kuwalola kuti aziyenda momasuka m'nyumba kuti asatseke mphemvu, zomwe za tarantula ndi bocato di cardinali.
