Ua ʻike ʻia kahi ilo ʻē ma ka Moana Pākīpika. Aia ke kū hoʻokahi o kēia meaola i ka mea i ke alo o kahi poʻo ʻaʻohe ona kino.
Ua ʻike ʻia ka mea i loaʻa mai kahi puke mana e like me Now Biology. Wahi a nā mea kākau moʻolelo moana ma ke Kulanui o Stanford, i ka helehelena, ua like kēia larva me kahi ilo o ka makua, nāna i hoʻoholo e hoʻonui mua i kona poʻo a hoʻomaka e ulu i ke kino ma hope. Mahalo i kēia, hiki i ka larva i kēia manawa ke ʻauʻau e like me ka pōpō i ke kai, e ʻohiʻohi ana iā plankton. ʻO ka mea nui paha, ʻo ka lohi o ka hoʻomohala ʻana he mea nui ia no ka larva, ʻoiai hiki ke ʻauʻau me ka ʻoi aku.
Ma ka ulia wale nō i loaʻa ai kēia ʻike - i ke kaʻina o ka ulu ʻana i nā larva o nā holoholona kai like ʻole i mea e kālailai ai i kā lākou metamorphoses, e hoʻomaka ana mai ke kahua o ka larva a hiki i kahi kanaka makua, ʻokoʻa loa ia.
Wahi a Paul Gonzalez (Ke Kulanui o Stanford, USA), ua kuhi ka poʻe ʻepekema i ka ulu ʻana o nā holoholona kai i ka hapanui o nā hihia i kēia ala. No laila, hopohopo nā biologists no ke aha a pehea i loaʻa ai iā lākou kēia hiki. A ʻo ka mea nui i keʻakeʻa iā mākou mai ka loaʻa ʻana o nā pane he paʻakikī paʻakikī a hoʻolōʻihi manawa e ulu i nā larvae o ia mau holoholona a nānā i ko lākou "ʻohana", e like ke ʻano o ke ola makua.
A i ka ʻimi ʻana i kahi meaola i kū ai ka poʻe kākau moʻolelo kai i kahi ilo ʻokoʻa loa. ʻO Schizocardium californiaicum kēlā e noho nei i ka Moana Pākīpika kokoke i Kaleponi. I ke ʻano makua, noho lākou i ke one o lalo, e ʻai ana i ke koena o nā holoholona e hāʻule ana i lalo o ke kai. ʻO kā lākou larvae, i ʻike ʻia e nā ʻepekema, ʻano like me ke poʻo o ke kanaka makua me ke kino ʻole. Mahalo i kēlā kino, hiki iā lākou ke "lana" i ka wai, e hānai ana i ka plankton.
ʻO ke kumu o kēia ke pio wale ʻia ʻana o nā gen i alakaʻi ʻia i ke kino i ka pae larval. A ke ʻai ka larva i kahi pae a ulu i kahi nui, huli kēia kele a ulu ke koena o ke kino i loko. Pehea ʻike ʻole ʻia ai kēia komo ʻana ʻaʻole i ʻike ʻia e nā ʻepekema, akā lana ka manaʻo e loaʻa kahi pane ma ka nānā ʻana i ka ulu ʻana o kēia holoholona a me ka hoʻomohala ʻana i nā ilo hemichordic, kahi kokoke loa iā Schizocardium californiaicum, akā ulu i ke ala maʻamau.
