ʻOi aku ka makaʻu o nā stingrays wai ma mua o nā piranhas ma ʻAmelika Hema: hiki iā lākou ke hōʻeha i nā ʻeha ʻeha me ko lākou mau mea ʻawaʻawa!

He aha ke ʻano o nā stingrays?
ʻO nā stingrays wai maʻemaʻe, e like me kā lākou inoa e hōʻike nei, he iʻa wai maʻemaʻe. E like me ka manō, pili lākou i ka iʻa cartilaginous. He mau iʻa kahiko loa kēia, ʻaʻohe iwi iwi, akā i hana ʻia me ka cartilage wale nō. Aneane poepoe a palahalaha loa ke ano o na stingrays. Ma muli o ke ʻano, he 25 kenimika ke anawaena o ko lākou kino a i hoʻokahi mika.
ʻO ka stingray Leopold, no ka laʻana, he 40 kenimika ke anawaena o ka wahine, he 50 kenimika ke kiʻekiʻe o ka wahine. Mai ka waha a i ka piko o ka huelo, hiki i ka 90 kenimika ke ana o ka stingrays. He ʻokoʻa nā kāne o ka stingray wai maʻemaʻe mai ka wahine ma muli o ka hoʻopili ʻana ma hope o ka wehe ʻana o ka maʻi, ʻaʻole i ka wahine.
Lawe nā kāne a me nā wahine i ka huelo ma ka hope o ko lākou kino me ka iwi kuamoʻo calcareous ma kahi o ʻekolu ʻīniha ka lōʻihi e hāʻule i waho i kēlā me kēia mau mahina a ua pani ʻia e kahi spine hou e ulu hou ana. ʻOkaʻiʻo loa ka ʻili o nā stingrays i ka wai maʻemaʻe a ua like ia me ke one. Mai nā unahi liʻiliʻi ma ka ʻili, i kapa ʻia hoʻi nā unahi placoid. E like me nā niho, aia nā niho a me ka enamel.
He ʻokoʻa ka waihoʻoluʻu ʻana o nā stingrays. He ʻoliva-ʻōmaʻomaʻo a hina-ʻeleʻele ke kino o ka stingray o Leopold me nā kiko keʻokeʻo, melemele, a ʻalani paha me nā palena ʻeleʻele.
Eia nō naʻe, ʻulaʻula ka ʻula ma ka ʻaoʻao o ka ʻōpū. Aia ma luna o ke poʻo nā maka i hāpai ʻia, hiki ke hoʻihoʻi ʻia. Hiki ke ʻike maikaʻi i nā ʻuo wai maʻemaʻe inā ʻaʻole ka mālamalama. ʻO kēia no ka mea, ʻo ko lākou mau maka, e like me nā maka o nā pōpoki, i kapa ʻia he koena kukui intensifiers. Aia ka waha, nā puka ihu, a me nā ʻāʻī ma lalo o ke kino.
Eia nō naʻe, ma ke ʻano he hoʻololi kūikawā i ke ola ma lalo o ka wai a me ka lepo, loaʻa iā lākou kahi hāmama hou aʻe: Ma waho aʻe o nā gills, loaʻa iā lākou ka lua i kapa ʻia ma hope o nā maka ma luna o ke poʻo. i hiki iā lākou ke omo i ka wai hanu ʻole i ka lepo a me ke one. Ulu hou nā niho o nā kukuna i ko lākou ola ʻana; ʻo ia hoʻi ke pani mau ʻia nei nā niho kahiko me nā niho hou.
Ma hea kahi e noho ai nā stingrays?
ʻO nā stingrays ka wai maʻemaʻe no ʻAmelika Hema. Eia naʻe, ʻike ʻia ka stingray a Leopold ma Brazil, no ka laʻana, ma kahi liʻiliʻi liʻiliʻi a he kakaikahi nō hoʻi: ʻike ʻia ma nā kahawai ʻo Xingu a me Fresco. Noho nā stingrays i nā muliwai nui o ʻAmelika Hema, ʻo ia hoʻi ma Orinoco a me Amazon.
ʻO wai nā stingrays wai ma laila?
ʻOi aku ma mua o 500 mau ʻano kukuna like ʻole ma ka honua, ʻo ka hapa nui o lākou e noho ana i ke kai, ʻo ia hoʻi i ka wai paʻakai. Aia ma kahi o 28 mau ʻano ʻano like ʻole i loko o ka ʻohana stingray wai maʻemaʻe, aia wale nō ma ka wai maʻemaʻe. ʻO ka Leopold stingray kahi mea i kapa ʻia he ʻano hopena, ʻo ia hoʻi, aia wale nō ia ma kahi liʻiliʻi liʻiliʻi i wehewehe ʻia.
ʻO kekahi ʻano ʻano ʻē aʻe, ʻo ka stingray peacock-eyed pili pili, ʻoi aku ka nui. Aia ia ma nā ʻāina nui ma nā muliwai nui e like me Orinoco, Amazon, a me La Plata. ʻOi aku ka māmā o kēia ʻano ma mua o ka stingray a Leopold. Ma muli o ka ʻāina, ʻike ʻia ma kahi o 20 mau ʻano kala like ʻole o ka stingray peacock-eyed.

Pehea ke ola o ka stingrays?
ʻAʻole nui ka ʻike e pili ana i nā stingrays wai. ʻO kekahi mau ʻano, e like me ka Leopold stingray, ua ʻike ʻia he ʻano ʻokoʻa mai ka hoʻomaka ʻana o nā makahiki 1990. ʻAʻole maopopo ka poʻe noiʻi inā ʻeleʻele lākou i ke ao a i ka pō paha.
Kanu lākou iā lākou iho i ka lepo ma lalo o ka muliwai e hiamoe ai. I ke ala ʻana, ʻimi lākou i ka lepo no ka ʻai. ʻAʻole lākou ʻauʻau wale i ka wai, ʻo ia ke kumu ʻaʻole ʻoe e ʻike iā lākou ma ke ʻano maoli - a i ʻole nā kiʻi ʻaneʻane pōʻai wale nō i waiho ʻia i ka lepo ke haʻalele lākou i ko lākou wahi moe.
Ma ʻAmelika Hema, ʻoi aku ka makaʻu o nā stingrays wai ma mua o nā piranhas: ke hehi hewa ʻole nā kānaka i nā kukuna e waiho huna ana ma lalo o nā kahawai. No ka pale ʻana iā ia iho, hou ka iʻa me kona ʻona ʻona: ʻeha loa nā ʻeha a hoʻōla maikaʻi ʻole. Hiki ke make ka mea make i nā keiki liʻiliʻi.
No ka pale ʻana i kēlā mau pōʻino, ua hoʻomohala ka poʻe o ʻAmelika Hema i kahi hoʻopunipuni: i ka wā e hele ai lākou i nā kapa one i ka wai pāpaʻu, e hoʻokuʻu lākou i ko lākou mau wāwae i ke one: e kuʻi wale lākou i ka ʻaoʻao o ke kukuna me ko lākou wāwae, a laila e ʻauʻau koke.
ʻO nā hoaaloha a me nā ʻenemi o nā stingrays wai
No ka mea, ua hūnā ʻia nā stingrays wai e like me ka Leopold stingray a hiki iā lākou ke pale pono iā lākou iho no ka hoʻomaikaʻi ʻana i kā lākou mau mea ʻawaʻawa, ʻaʻohe o lākou ʻenemi maoli. ʻO ka hapa nui, hāʻule nā kukuna ʻōpio i nā iʻa predatory ʻē aʻe. Eia nō naʻe, ʻai ʻia lākou e nā kamaʻāina a ʻai ʻia nō hoʻi lākou no ke kālepa iʻa nani.
Pehea ka hanau hou ana o na stingrays?
Hānau ʻia nā stingrays i nā ʻōpiopio ola. Hiki ke oʻo ka wahine i ka makahiki ʻelua a ʻehā makahiki. ʻO ka hoʻokumu ʻana, hiki ke hala 20 a 30 mau minuke, moe nā holoholona i ka ʻōpū i ka ʻōpū.
Ma hope o ʻekolu mahina, hānau nā wahine a hiki i ka ʻumikūmālua mau ʻōpio, nona ke anawaena o ʻeono a 17 kenimika. Ua hoʻomohala ʻia nā kukuna pēpē a kūʻokoʻa loa. Manaʻo ʻia naʻe, pili lākou i ko lākou makuahine i nā lā mua e pale iā lākou iho mai nā mea ʻaihue.
Pehea ka ʻimi ʻana o nā stingrays wai?
He iʻa predatory ka stingrays. ʻO nā pectoral fins e like me ka fringe, kahi e noho ai nā mea ʻike, e noho ma ka ʻaoʻao o ke kino. Penei ko lakou ike ana i ka lakou pio. Ke hoʻopā koke lākou i ka mea pio me kā lākou pectoral fi, e pane koke lākou a lawe i ko lākou waha. Kau lākou i ko lākou kino holoʻokoʻa ma luna o nā iʻa nui aʻe a hoʻopaʻa i ko lākou mau pectoral e paʻa i kahi.
