Nkhanu ya mzimu (Ocypode quadrata) ndi ya gulu la crustacean.
Nkhanu kufalitsa ndi mizukwa.
Malo a nkhanu yauzimu ili pakati pa 40 ° C. sh. mpaka madigiri 30, ndipo akuphatikizanso gombe lakum'mawa kwa South ndi North America.
Mitunduyi imachokera ku Chilumba cha Santa Catarina ku Brazil. Mitunduyi imakhalanso m'chigawo cha Bermuda, mphutsi zapezeka kumpoto kwenikweni pafupi ndi Woods Hole ku Massachusetts, koma palibe achikulire omwe apezeka patali.
Malo okhala nkhanu ndi mizukwa.
Nkhanu za Ghost zimapezeka kumadera otentha ndi otentha. Amapezeka m'malo okhala ndi magombe otetezedwa. Amakhala m'dera la supralittoral (zone of the spring funde line), amakhala m'mphepete mwa mchenga pafupi ndi madzi.
Zizindikiro zakunja za nkhanu ndi mizukwa.
Nkhanu yauzimu ndi nkhanu yaing'ono yokhala ndi chipolopolo cha chitinous chotalika masentimita 5. Mtundu wa integumentyo ndi wachikasu kapena wachikasu. Carapace ndi yamakona anayi, yozungulira m'mbali. Kutalika kwa carapace kumakhala pafupifupi zisanu ndi zisanu ndi chimodzi mwa sikisamba m'lifupi. Pali burashi wandiweyani wa tsitsi lakunja kwa miyendo iwiri yoyamba. Ma Chelipeds (zikhadabo) zazitali zosafanana amapezeka pamagulu omwe adasinthidwa poyenda kutalika. Maso amatumbuluka. Wamphongo nthawi zambiri amakhala wamkulu kuposa wamkazi.
Kuswana nkhanu - mizukwa.
Kubalana mu nkhanu zauzimu kumachitika chaka chonse, makamaka mu Epulo - Julayi, amatha kukwatirana nthawi iliyonse atatha msinkhu. Izi ndizosinthidwa ndi moyo wapadziko lapansi. Kukhathamira kumachitika nthawi yomwe chivundikiro cha chitinous chimauma kwathunthu ndikukhala cholimba. Kawirikawiri nkhanu zamzimu zimakwatirana kulikonse kapena pafupi ndi dzenje laimuna.
Akazi amatha kuberekana pamene zipolopolo zawo zimakhala zazikulu kuposa 2.5 cm.
Carapace ya amuna mu nkhanu okhwima ogonana 2.4 cm. Kawirikawiri nkhanu - mizukwa imapatsa ana ali ndi zaka pafupifupi chaka chimodzi.
Mkazi amabala mazira pansi pa thupi lake, panthawi yobereka, amalowa m'madzi nthawi zonse kuti mazira akhalebe onyowa komanso kuti asamaume. Zazikazi zina zimadzendanso m'madzi kuti ziwonjezere madzi komanso mpweya wabwino. Mwachilengedwe, nkhanu zauzimu zimakhala zaka pafupifupi zitatu.
Makhalidwe a nkhanu ya mzimu.
Nkhanu - mizukwa nthawi zambiri imakhala usiku. Anthu a Crustaceans amapanga maenje atsopano m'mawa kapena amakonzanso akale. Kumayambiriro kwa tsiku, amakhala m'mayenje awo ndi kubisala mmenemo mpaka kulowa kwa dzuwa. Ma burrows ndi a 0.6 mpaka 1.2 mita kutalika ndipo pafupifupi m'lifupi mwake. Kukula kwa khomo ndikofanana ndi kukula kwa carapace. Achinyamata, nkhanu zazing'ono zimakonda kubowola pafupi ndi madzi. Podyetsa usiku, nkhanu zimatha kuyenda mpaka mita 300, motero sizibwerera kubowola lomwelo tsiku lililonse. Nkhanu zam'madzi zimabisala m'mabowo kuyambira Okutobala mpaka Epulo. Mtundu wa crustacean uli ndi mawonekedwe osangalatsa amoyo wapadziko lapansi.
Nkhanu - mizukwa nthawi zambiri imathamangira kumadzi kukanyowetsa mphutsi zawo; Koma amatha kutunganso madzi panthaka yonyowa. Nkhanu za Ghost zimagwiritsa ntchito ubweya wabwino womwe uli pansi pamiyendo yawo kuyendetsa madzi kuchokera mumchenga kupita m'makutu awo.
Nkhanu za Ghost zimabowola mumchenga wonyowa mdera la 400 mita.
Nkhanu zauzimu zimapanga phokoso lomwe limachitika zikhadabo zitaphulika pansi. Chodabwitsa ichi chimatchedwa stridulation (rubbing) ndipo "phokoso laphokoso" limamveka. Umu ndi momwe amuna amachenjezera zakupezeka kwawo kuti athetse kufunikira kogonana ndi wopikisana naye.
Chakudya cha nkhanu ndi mizukwa.
Nkhanu - mizukwa ndi yolusa komanso yodyetsa, imangodya usiku. Nyamayo imadalira mtundu wam'mphepete mwa nyanjayi. Nkhanu zomwe zili m'mphepete mwa nyanja zimakonda kudya ziphuphu za Donax ndi nkhanu za Atlantic, pomwe pagombe lodyera kwambiri amadyera mazira ndi ana amchere a kamba wam'madzi wam'madzi.
Nkhanu za Mzimu zimasaka usiku kwambiri kuti muchepetse kudyedwa ndi ophulitsa mchenga, mbalame zam'madzi kapena ma raccoon. Akachoka pamabowo masana, amatha kusintha pang'ono mtundu wa chivundikirocho kuti chikugwirizana ndi mchenga wozungulira.
Udindo wa nkhanu ndi mizukwa.
Nkhanu - mizukwa m'chilengedwe chawo ndi nyama zolusa ndipo ndi gawo la unyolo.
Zakudya zambiri zama crustaceans ndizamoyo, ngakhale zilinso ndi zonyamula (zosankha) zokhazokha.
Nkhanu za Ghost ndi gawo lofunikira la chakudya, zomwe zimagwira gawo lofunikira pakusamutsa mphamvu kuchokera ku organic detritus ndi tizilombo tating'onoting'ono tating'onoting'ono kupita kuzikudya zazikulu.
Mitundu iyi ya crustacean imakhudza kamba. Akuyesera kuchepetsa kudya kwa mazira akamba ndi nkhanu.
Kafukufuku wasonyeza kuti nkhanu zam'madzi zimadya mazira akamba pafupifupi 10% akamasaka, komanso amapha nsomba mwachangu. Nthawi zina, amawononga maenje obisika ndikukopa ma raccoon omwe amasaka nkhanu.
Nkhanu - mzimu - chizindikiro cha mkhalidwe wa chilengedwe.
Nkhanu za Ghost zimagwiritsidwa ntchito ngati zisonyezo zowunika momwe zochita za anthu zimakhudzira magombe amchenga. Kuchuluka kwa kuchuluka kwa ma crustaceans kumatha kuwerengedwa mosavuta powerengera kuchuluka kwa mabowo omwe adakumbidwa mumchenga pamalo ena. Kuchuluka kwa malo okhala kumachepa nthawi zonse chifukwa cha kusintha kwa malo okhala ndi kufinyika kwa nthaka chifukwa cha ntchito za anthu. Chifukwa chake, kuwunika nkhanu zakuthambo kudzathandiza kuwunika momwe zochita za anthu zimakhudzira zachilengedwe za m'mphepete mwa mchenga.
Mkhalidwe wosamalira nkhanu ndi mzimu.
Pakadali pano, nkhanu zamoyo sizomwe zili pangozi. Chimodzi mwazifukwa zazikulu zakuchepa kwa nkhanu ndikuchepa kwa malo okhala chifukwa chakumanga nyumba zogona kapena malo oyendera alendo kumtunda kwamakalata. Chiwerengero chachikulu cha nkhanu zauzimu chimamwalira pansi pa magudumu amgalimoto zapamsewu, zomwe zimasokoneza njira yodyetsera usiku komanso kuzungulira kwa ma crustaceans.
