Thrasher: kufotokoza, malo okhala ndi chidwi mfundo

Mwamunayo anam'patsa dzina anthu a nyanja, motsogozedwa ndi muyezo zachilendo. Nthawi zambiri ntchito maina a nyama lapadziko, amene osachepera kufanana lakutali kapena makhalidwe ofanana. Choncho, amalinyero otchedwa ndi manatee nyanja ng'ombe chifukwa cha kukula lalikulu ndi kusakwiya chenicheni. Ndipo dzina munakhala thrasher oimira angapo kuya.

oopsa chilombo

Mu madzi a Pacific ndi Indian Nsomba zopezeka m'nyanja zikuluzikulu lalikulu chilombo - nkhandweyo nsombazi. M'litali pafupifupi kungakhale mamita sikisi, ndi kulemera - 400 makilogalamu. Dzina ambiri a mtundu wa nsomba, monga inu mwina anaganiza, thrasher. Shark nacho icho chifukwa cha mchira wautali, kapena kukhala enieni kwambiri, ndi Lobe kumtunda kwa chipsyepsye caudal. chipangizo Zimenezi zimathandiza chilombo kutulutsa chakudya chawo. Ndipo monga izo zimachitika, kuyesa kufotokoza mwatsatanetsatane.

Kodi kusaka nsombazi, wotchedwa nyanja nkhandwe

Thrasher kawirikawiri akuukira nyama mwachindunji. Lidalembedwa kwa kusaka kusintha elongated gawo la chipsyepsye caudal. Kupeza sukulu ya nsomba ndi chilombo mofulumira akuswa ku pakati ndi kuyamba anatenga mchira. Koma zinalephereka chipsyepsye stun nyama, ndipo nsombazi zitha kudya nsomba akadali.

Chimodzi kapena zingapo?

Nsombayi ndi khalidwe mchira chipsyepsye a mtundu womwewo, koma anawagawa mitundu itatu:

• Sitima wamba nkhandweyo.
• Fox kwambiri (hemigaleidae).
• Pelagic nsombazi wa mtundu nkhandweyo.

Kutalika kwa mchira chipsyepsye aliyense woimira mtundu uwu - oposa theka kutalika kwa thupi lake. Wochepetsetsa munthu polimbana ndi mdani pansi pa nyanja. makhalidwe ake bwino bwino, koma pakuona anauza misonkhano iyi kawirikawiri kha mchira chachikulu nsomba anamuyika, pokhala pa sitima nsomba bwalo, anabweretsa kuwonongeka wautali kwambiri ndi kuvulaza asodzi.

Fox pelagic nsombazi limagwira kwambiri infrequently. Chifukwa peculiarities makhalidwe kupha kupanga makamaka aikidwa pa nsomba mbedza si pakamwa ndi mchira chipsyepsye.

thresher Common kumachitika kawirikawiri. Iye ali yaikulu malo - kuchokera kotentha kuti kugombe la Norway. nsomba ndi lalikulu kwambiri pa nkhandwe onse. Iwo akhoza kukula kwa mamita asanu.

❖ kuyanika a mitundu yosiyanasiyana zimasiyanasiyana imvi bulauni kuti imvi mdima. Nthawi zina nsomba kungakhale buluu. Kumbuyo nthawi zonse akuda kuposa mimba. M'mimba ndi pectoral zipsepse nkhandweyo nyanja mwina mawanga woyera.

Monga kuchulukana tailed chilombo

Fox amatanthauza nsombazo viviparous. wamkazi munthu sabadwa zosaposa ana awiri pa nthawi yomweyo. Ngakhale kutchedwa mwana nkhandweyo Bakuman nsombazi ndizo kovuta. M'litali pobadwa - pafupifupi imodzi ndi mamita theka. Panthawi yakutha msinkhu, "ana" akukulira kuti mamita anayi.

wosazindikira amakedzana

Nthawi zambiri, nsombazo - mtundu wakale kwambiri wa nsomba. Asayansi akukhulupirira kuti zaka 400 miliyoni zapitazo, ogwirira awa ankasakidwa mu kuya kwa nyanja. Zimenezi akhoza zimachitika angapo dongosolo wosazindikira kwa nsombazo. Tiyeni tiyambe ndi choona kuti mtundu wa nsomba cartilaginous, mwachitsanzo fupa iwo satero. Ndipo nsombazo palibe gill chimakwirira. Komabe, ogwirira wakale osangalala ngati ano, ndi zosatheka wolephera zambiri mitundu "mnyamata".

Wina nyama - scat

Dzina thrasher akadali munakhala ndi nthumwi imodzi dziko m'madzi. Chotero anaitana spiny (yaminga) kunyezimira. Ndi nsomba pansi mawonekedwe penapake zachilendo. Iwo umakhala mu Atlantic, Mediterranean ndi Black Pacific.

Chidwi nyama, nyanja nkhandwe, ali ndi diamondi woboola pakati lathyathyathya thupi ndi yaitali, yopapatiza mchira. Anthu ambiri mchira kutalika wofanana ndi kutalika kwa thupi. Back ndi pamwamba pa mchira wa wamkulu spiny yenda momyata ali minga mzere. chiwerengero akhoza kukhala zidutswa mpaka makumi awiri. Mchira umatha ndi awiri zipsepse yaing'ono dorsal. Scat thrasher ali aafupi mutu ndi thupi lake, ngakhale kuti si wozungulira, wotchedwa chimbale cha.

Zina kunyezimira kwa

Ambiri ndiziwunda nthawi m'madzi Fox anagwira m'manda ku silty kapena mchenga pansi. Favorite kuya - kuchokera makumi awiri kuti meters mazana atatu, koma panali milandu kudziwika oimira munthu pa akuya 550 m.

mitundu ili rombovym otsetsereka ndi monga thresher nsombazi, cartilaginous nsomba banja. Izo wakudya mphutsi, mphutsi, ngale yaing'ono, onse amene amatchedwa liwu limodzi - benthos. Nthawi zina mu zakudya akulu nkhanu pano ndi nsomba zina zing'onozing'ono.

Kutalika kwa nkhandwe nyanja wamwamuna ali ochepa, palibe kuposa masentimita 70. Wamkazi ndi yokulirapo. Anthu ena amakula masentimita 120.

kubalana

Scat thrasher amatanthauza yaytserodyaschim mitundu, mazira mwachitsanzo kukhala kunja kwa thupi la mayi. Mwamuna kapena mkazi ndiziwunda m'chaka, iwo yodziwika ndi umuna mkati. Kenako wamkazi amaikira mazira masabata ochepa. Zimenezi tsiku kumabweretsa 50-150 mazira nyengo. mazira stingray ndiotetezedwa ndi kapisozi wandiweyani njira yapadera lateral. Iwo ali ngati ulusi zimene zaikidwa algae kuti zigwiridwe, dzira mu malo.

Young mazira kuoneka mu miyezi 5. ndiziwunda Small ndi kutalika 12-13 cm. Mphamvu Kids amapangidwa paokha, kawirikawiri amakhala chakudya zikuluzikulu nsomba zolusa. Wapakati moyo amayembekezeka limbikitsa thrasher - zaka 15-17. Unamwali, amuna ndi akazi kufika pafupi usinkhu wa zaka zisanu ndi zitatu.

The zipsepse pectoral a nkhandwe nyanja (Nsombayi ndi cheza)

N'zochititsa chidwi kuti tione kusiyana kwakukulu pakati pa Nsombayi ndi cheza ndi dzina lomweli. Fox Shark ofanana ndi oponya moyo kuti chikusesa mwa kuya kwa nyanja. A nkhandweyo scat amaoneka ngati chinsalu chachikulu chimene chimachititsa kuti kudzera kayendedwe undulating. The mawonekedwe thupi la nsombazo ndi kunyezimira ali malinga ndi zamoyo za mtundu, chifukwa akhala ndi moyo osiyana.

Mosiyana anayamba zipsepse pectoral a nkhandwe nyanja. Ntchito yawo zimadalira mtundu wa nsomba;

• Pectoral zipsepse za nsombazi nyanja nkhandwe ndi kwa mtendere wa thupi. Iwo salola masikono chilombo kumtunda mbali. Ndipo ndi mtundu wa "zikepe".
• Pa nyanja stingray nkhandweyo pectoral zipsepse ntchito ndandanda. Iwo ndi m'mbali modabwitsa yotakata zimene zinaphatikizidwa ndi mbali pamwamba pa thupi ndi mutu.

Choncho, chifukwa peculiarities wa Kapangidwe ka pectoral zipsepse za nsombazi nawo mwayi kusambira mofulumira ndi mwachangu akamagwiritsa pa kusaka ndi. A limbikitsa thrasher akhoza bwino ndipo mosavuta kusuntha mu ndime madzi, kutenga chakudya chabwino.

Ndipotu, stingrays ndi nsombazo - achibale. Onse mitundu a nsomba wakale cartilaginous. Komabe, zamoyo pang'onopang'ono kusintha kwa kapangidwe ka osewera ake, ndi lero ndi kukhulupirira zimakhalira pachibale amenewa.
