ʻ platypus he holoholona hoihoi loa. Mai kona ʻike ʻana he paʻakikī loa e hoʻokaʻawale iā ia no ka mea he ʻokoʻa nā ʻano holoholona. He hulu kona, nuku o ka ʻāpō, hoʻomoe ia i mau hua manu a ʻo ka mea e hānai ai i kāna keiki.
He ʻano laha ia i ka hikina o Australia a me ka mokupuni ʻo Tasmania. Loaʻa kona inoa mai ka Greek ornithorhynkhos, ʻo ia hoʻi "pēpē-like’.
I kēia ʻatikala na PeritoAnimal kamaʻilio mākou e pili ana i kēia holoholona ʻano ʻē. E ʻike ʻoe pehea e ʻimi ai, pehea e hānau ai a no ke aha he ʻano ʻokoʻa kona. E hoʻomau i ka heluhelu a ʻike mea lapuwale e pili ana i ka platypus.
He aha ka platypus?
ʻO ka platypus kahi māmela monotreme. ʻO Monotremes kahi kauoha o nā māmela me nā ʻano reptilian, e like me ke kau ʻana i nā hua manu a i ʻole ka loaʻa ʻana koloka. ʻO ka cloaca kahi orifice i ka hope o ke kino kahi e hui ai ka mimi, digestive a me nā ʻōnaehana hānau.
Aia he 5 mau lā ola o monotremes. ʻ ʻO Platypus a me nā monotremates. ʻAno like nā monotremates me nā hedgehogs maʻamau akā kaʻana like i nā ʻano hoihoi o nā monotremes. He holoholona mehameha a maʻalahi hoʻi nā mea āpau, kahi e pili wale ai kekahi i kekahi i nā wā kau male.
mea ʻawahia
ʻO ka platypus kekahi o nā mammal ma ka honua nei he lāʻau make. kāne a spike i kona mau wāwae hope e hoʻokuʻu i ka mea make. Ua hūnā ʻia e nā ʻōiwi iwi. Hānau pū ʻia nā wahine me lākou akā ʻaʻole hoʻomohala ma hope o ka hānau ʻana a nalowale ma mua o ka wā makua.
He lāʻau make ia me nā toxins lehulehu i hana ʻia e ka ʻōnaehana pale ʻino o ka holoholona. He mea make ia i nā holoholona liʻiliʻi a ʻeha loa no nā kānaka. Hōʻike ʻia nā kūlana o nā mea lawelawe i ʻeha nui i nā lā he nui.
ʻAʻohe lāʻau lapaʻau no kēia lāʻau make, lawelawe wale ʻia ka mea maʻi e pale aku i ka ʻeha o ka ʻū.
Uila uila
Hoʻohana ka platypus i a ʻōnaehana uila e alualu i kā lākou mea pio. Hiki iā lākou ke ʻike i nā māla uila i hoʻokumu ʻia e kā lākou mea pio i ka wā e ʻaelike ai lākou i ko lākou mau mākala. Hiki iā lākou ke hana i kēia me ke aloha i nā pūnaewele electrosensory i loaʻa iā lākou ma ko lākou ʻili puʻupuʻu. Loaʻa iā lākou nā pūnaewele mechanoreceptor, nā hunaola kūikawā no ka hoʻopā ʻana, hāʻawi ʻia a puni ka ihu.
Hana kēia mau pūnaewele i ka ʻahamele e hoʻouna i ka lolo i ka ʻike e pono ai e hoʻokokoke iā ia iho me ka ʻole o ka hoʻohana ʻana i ka pilau a i ʻole ka ʻike maka. Maikaʻi loa ka ʻōnaehana mai ka pani ʻana o ka platypus i kona mau maka a hoʻolohe wale ma lalo o ka wai. Luu ʻo ia i loko o ka wai pāpaʻu a ʻeli i ka lalo me ke kōkua o kona waha.
ʻO ka mea e neʻe ana ma waena o ka honua e hoʻoulu i nā māla uila liʻiliʻi i ʻike ʻia e ka platypus. Hiki iā ia ke hoʻokaʻawale i nā mea ola mai nā mea inert a puni ia, ʻo ia kekahi o nā curiosities keu loa e pili ana i ka platypus.
He a holoholona kikokiko, hānai nui i nā ilo a me nā kolo, nā crustacea liʻiliʻi, nā larvae a me nā anelid ʻē aʻe.
moe hua
E like me kā mākou i ʻōlelo ai ma mua, platypus nō monotremes. He mau māmele lākou i hoʻomoe i nā hua. Hiki i nā wahine ke oʻo i ka moekolohe mai ka makahiki mua o ke ola a hoʻomoe i hoʻokahi hua i kēlā me kēia makahiki. Ma hope o ka hoʻopili ʻana, heʻe ka wahine lua lua kūkulu ʻia nā lua hohonu me nā pae ʻokoʻa e mālama i ka mahana a me ka wela. Pale pū kēia ʻōnaehana iā lākou mai ka piʻi ʻana o ka wai a me nā mea ʻino.
Hana lākou i kahi moena me nā pale a waiho ma waena 1 a 3 mau hua 10-11 millimeter i ke anawaena. he mau hua liʻiliʻi lākou i ʻoi aku ka pōʻai ma mua o ko nā manu. Hoʻolālā lākou i loko o ka kōpū o ka makuahine no 28 mau lā a ma hope o 10-15 mau lā o ka hoʻouka waho e hānau ʻia nā keiki.
Ke hānau ʻia ka platypus liʻiliʻi palupalu loa lākou. He lauoho ʻole a makapō hoʻi lākou. Hānau ʻia lākou me nā niho, a lākou e nalo i kahi manawa pōkole, a waiho wale i nā pāhoʻi horny.
Omo lākou i kā lākou keiki
ʻO ka ʻoiaʻiʻo o ka omo ʻana i kā lākou keiki he mea maʻamau ia i nā māmela. Eia nō naʻe, nele nā platypus i nā nipples. No laila pehea ʻoe e hānai ai?
ʻO kekahi mea hoihoi e pili ana i ka platypus ʻo ka loaʻa ʻana o nā wahine mammary i nā wahine i loko o ka ʻōpū. No ka mea ʻaʻohe o lākou nipples, e hūnā i ka waiū ma o nā pores o ka ʻili. I kēia wahi o ka ʻōpū aia nā pūwaha kahi e mālama ʻia ai kēia waiū i ka wā e kipaku ʻia ai, i palu ai nā ʻōpio i ka waiū mai ko lākou ʻili. ʻO ka manawa omo o nā keiki he 3 mau mahina.
Lokomaikaʻi
me he holoholona lā semi-aquatic he a ʻauʻau kai maikaʻi loa. ʻOiai he ʻehā ona wāwae i wili ʻia, hoʻohana wale ia i nā forelegs e ʻauʻau ai. Hoʻopili nā wāwae hope iā lākou i ka huelo a hoʻohana iā ia ma ke ʻano he hoe i loko o ka wai, e like me ka iʻa.
Hele lākou i ka ʻāina like like me ka mea kolo. No laila, a me kahi hoihoi e pili ana i ka platypus, ʻike mākou he mau wāwae ko lākou ma nā ʻaoʻao a ʻaʻole ma ka lalo e like me nā mea ʻimi ʻē aʻe. He primitive ka iwi iwi o ka platypus, me nā wēlau pōkole, e like me ko ka otter.
Nā Genetics
Ma ke aʻo ʻana i ka palapala ʻāina o ka platypus, ua ʻike nā ʻepekema i ka hui ʻana o nā ʻano i loko o ka platypus ke ʻike ʻia i loko o kāna mau genes.
Loaʻa iā lākou nā hiʻohiʻona i ʻike wale ʻia i nā amphibians, nā manu a me nā iʻa. Akā ʻo ka mea hoihoi loa e pili ana i ka platypuse ko lākou ʻōnaehana chromosome moekolohe. Loaʻa i nā mamamela e like me mākou he 2 chromosome wahine. Eia naʻe, ka platypus he 10 mau chromosome wahine.
ʻO kā lākou chromosome moekolohe e like me ka manu ma mua o ka mammal. I ka ʻoiaʻiʻo, nele lākou i ka māhele SRY, kahi e hoʻoholo ai i ka moekolohe kāne. Ma kēia manawa ʻaʻole i ʻike pololei ʻia pehea e hoʻoholo ʻia ai ka moekolohe i kēia ʻano.
