Lamprey Mtsinje - mtundu wa chilombo-tiziromboti kuti zinasungidwa ku Kale

Lamprey Mtsinje ali wa gulu la cyclostomes nsomba (Cyclostomata), lampreys subclass (Petromyzones). Kamakhala m'mitsinje. Mu Russia, n'lopindulitsa malonda.

Ilinso ndi elongated, njoka ngati kuti thupi 40 cm yaitali, yokutidwa ndi mucous khungu adachitira umboni. Mtundu wa ake mdima-imvi ndi Sheen zachitsulo. Pakamwa prisasyvatelnoy kusungidwa mu hopper, ndi m'mbali mwa zomwe zili pa lilime, mano. Nsagwada ayi. Pamwamba pa mutu uli unpaired m'mphuno kutsegula. maso ake anali atatu, awiri amene zambiri akupangidwa ndi wachitatu amaona kuwala kokha, chifukwa pakalibe disolo.

Kupuma amaperekedwa awiriawiri isanu ndi iwiri ya matumba branchial ili m'mbali mwa thupi ndi kutsegula kunja. Mafupa tichipeza chichereŵechereŵe. Iwo amayandama, kupinda thupi, pafupifupi monga njoka. Awiri zipsepse dorsal (kawirikawiri munthu), caudal chipsyepsye ravnolopastny, onse mothandizidwa ndi kunyezimira cartilaginous. zipsepse wophatikizidwa alibe lamprey mtsinje. Photo limasonyeza labwino.

Lamprey Mtsinje lagawidwa ndi bushing (okhala m'madera a m'mphepete mwa nyanja nyanja desalinated ndipo zimaswana mu mitsinje) ndi khomo limodzi (tikukhala mu mitsinje).

Lamprey Mtsinje - mtundu wa chilombo ndi tiziromboti. Amalidyetsa ndi suction kwa okhalamo amadzimadzi amakonda nsomba ndi kuwakwatula cha thupi ndi magazi. Iye wosusuka wina suction chikho, zomwe ukhoza kwa masiku ambiri, akhoza kukoka kuchokera wozunzidwayo ndi zambiri za thupi lawo. nsomba zambiri pambuyo "kukambirana" kufa cha zilonda zake, monga magazi awo akhale chinthu zoletsa kuti clotting.

Chaka pamaso spawning lamprey mtsinje ikutha kudya. Mu thupi lake pali kusintha kwakukulu: ziwole intestine, England malovu kufa, zipsepse dorsal ndi ophatikizidwa mu imodzi, akazi limapezeka pa chipsyepsye kumatako ndi mazira kupangidwa, ndi wamwamuna - papilla maliseche ndi mkaka. M'litali ndi kulemera mu amuna ndi akazi amachepetsa.

Zimafalitsidwa mtsinje lamprey m'zigawo za mtsinje ndi othamanga pansi panopa ndi ndilamiyala, pa akuya. Pa spawning, aamuna amanga chisa ndi kukumba maenje mu pansi. Female nthawi zonse akuyandama pa iye, kukhudza mimba ya mutu wake, ngati ankakuwa. Mapeto ali kwangochepetsako pang'ono chabe chimakula dzenje. Pamene anamaliza wamkazi kamadzimamatiza kwa thanthwe pafupi chisa, ndi wamwamuna amakhulupirirabe izo, pang'onopang'ono chimakankhira ndi suction chikho mbali ya mutu ndi mchira opangidwa pa iye. Zamgululi wa zopangitsa ndi ubereki anaponyedwa imodzi. Pambuyo spawning, makolowo wabisika mwa miyala ndipo posakhalitsa afa.

Mazira, umene uli oposa 20 zikwi, 2 masabata mphutsi kuoneka otchedwa peskoroykami. Iwo amayang'ana ngati mphutsi yaing'ono chikasu mtundu. About 4 masiku iwo kubisa pakati pa miyala pansi mtsinje, ndipo anafika 6 mm m'litali, anaikidwa mu matope. masiku 15 mphutsi kusiya kubisala ake ndi kupita ndi otaya ndi, kuima kumene adzaikidwa m'manda mu matope ndi kudya zatsalira algae. Mbali larval kumatenga za 5 zaka. Pambuyo metamorphosis amapezeka siteji wamkulu, imene tiziromboti pa mtsinje lamprey anthu ena mtsinje.

Izi cyclostomes nsomba zoipa sagwirizana kuwala. Yachokera pa nsomba ake. Asodzi adatchithisira pa mbali zonse za mtsinje magetsi amphamvu kuti pakati inali njira yopitira mdima, ndipo iwo anakhala msampha kuti limagwira ndi kugwa.

Nthawi imeneyi, mtsinje lamprey ali ndi makhalidwe kwambiri kukoma. Ndipo pamene inu kuganizira kuti mafupa ya ndulu ake ndi matumbo ayi, ndiye mankhwala wangwiro kuti akhoza kudya lonse. Pamaso kuphika izo ndi kutsukidwa kwa ntchofu ndi yokazinga mu ziwaya, nthawi zina kuzifutsa.
