The mbali lamkati la chipolopolo ndi chikasu woyera. chachikulu wamwamuna misa angafikire 7 makilogalamu carapace m'lifupi - 28 cm, kutambalala miyendo pakati -. 1,5 mamita Kuti moyo mpaka zaka 20, akapanda gwidwa ndi musadye. Adani anthu, nyamayi, gobies, m'nyanja zikuluzikulu otters nyanja, ndi ena.

Kamchatka nkhanu chaka pa njira yomweyo, ulendo wawo. Iwo m'nyengo yozizira pa akuya pafupifupi 250 m, ndi kusamuka masika m'madzi osaya, kukhetsa ndi kuchulukitsa. M'dzinja anatumiza mmbuyo, m'madzi akuya. madzi kusintha kutentha chizindikiro akutumikira kusuntha. Nkhanu Usaigwedezere yekha, iwo kusuntha kwambiri, zikwi zikwi mazanamazana. Komanso, amuna lalikulu ndi azisiyanitsidwa achinyamata ndi akazi. M'chaka cha nkhanu ndi chilonda mpaka makilomita 100 pa nyanja.

nkhanu wamkulu moult 1 pa chaka. Molting kumatenga masiku 3, masiku ano amuna ndi kubisala pansi miyala, m'manda mu maenje. Pamodzi ndi zida iwo kusinthidwa mu matumbo, ndi kum'mero, khoma m'mimba, tendon.

Kulera chipolopolo, akazi umabala mazira (mazira zingakhale za 20,000 kuti 445,000) pansi pamimba. Iye wakwerapo miyezi 11,5. Chaka chotsatira, akusuntha mu madzi osaya, mphutsi kutuluka mazira, pamene akazi Ziyendanibe. Akazi kutchera mazira 1 nthawi chaka, ndi mwamuna angathe amamuchitira ndi akazi angapo pa kuswana nyengo.

Kamchatka nkhanu okhwima mochedwa, akazi akhwime kugonana ndi zaka 8, ndi amuna - zaka 10. Zachilendo chibwenzi mwambo. Chiombankhanga akugwira kwa mzake, iwo angakhoze kuima masiku 3-7. The wamkazi thandizo wamwamuna m'kati molting, ndiyeno iwo amamuchitira.

Mphutsi kupulumuka pang'ono, za 4%. Nthawi yoyamba larva ikuyandama m'madzi, adagwidwa ndi kayendedwe ka m'kamwa mwa. Ndiye izo zikukhazikitsa pansi, kukhala algae lapansi. zaka zitatu zokha, iye masamba malo, popeza anakhetsa kangapo. Amasamukira kumayambira zaka 5-7.

Mfumu nkhanu - chinthu cha nsomba yotheka, koma zaposachedwapa okha chifukwa kuchepetsa chiwerengero chawo. Nkhanu nyama - lofunika zakudya mankhwala, zophikiratu munali mavitamini A, PP, C, gulu B ndipo tifufuza zinthu. The ofunika kwambiri pomwe claw. Carapaces ndi viscera alinso mlandu wawo apange feteleza kwambiri.
