Vachiramba vachichinja-chinja pakadzika pegungwa, maeel akasviba-tema akakwezva vaongorori sezvavanoita kunge vari kushanduka kuitira kushandisa nzira yekuvanza. Nemiswe yadzo inopenya, mbira dzinokwanisa kuswededza mhuka dzadzo pedyo dzisati dzadzidya neshaya dzadzo dzinotyisa.
Ongororo yemhando dzeAnguilloidei (kusanganisira eels yemvura yakachena, spaghetti eels uye transparent one jaw eels) yakaratidza kuti rima pigmentation rakazvimiririra pane kanopfuura chiitiko chimwe. Mienzaniso yeizvi inosanganisira madzitateguru epelican eels (Eurypharynx pelecanoides), swallower eels, bobtail eels, snipe eels, uye sawtooth eels.
Zvakawanikwa zveongororo yazvino zvakaburitswa mujenari Environmental Biology yeHove musi waChikunguru 11, 2020, ichipa kunzwisiswa kuri nani kwemaitiro ezvisikwa zvakadzika-mugungwa, mazhinji acho asati anyatso dzidza.
Pasinei nechokwadi chokuti gungwa rakadzika ndiro nzvimbo yakakura yezvisikwa zvepasi, isu tichiri kunzwisisa zvishoma nezvazvo, maererano naMike Ghedotti, purofesa wezvinyorwa zvegungwa uye ichthyology paRegis University muDenver. Akataurawo kuti kuongorora gungwa rakadzika inzira inodhura uye hazviitike kakawanda sekuongorora gungwa risina kudzika.
Mboro, kana kuti deep-sea, eel, kazhinji inogara uye inovhima mukatikati megungwa "Midnight Zone," pakati pe3,300-13,100 metres (1,000-4,000 metres) umo pasina chiedza chezuva chinogona kupinda. Rima risingaperi iri rakamonyanisa miviri yemboro nenzira dzinoshamisa, nemuromo wepelican eel muenzaniso mukuru wekutambanudza simba risingaenzaniswi nemamwe marudzi ese. Kuongorora mabasa ezvisikwa izvi zvakadzama kudaro kwaratidza kuva kwakaoma zvikuru.
Mukuedza kujekesa maitiro asinganzwisisiki emvura yakadzika-gungwa, vatsvakurudzi vakanyatsotarisa ganda reganda repelican eel pasi pe microscope. Pakuongorora, masayendisiti akaona imwe jet-black pigmentation yakapararira kumiviri yezvisikwa.
Ongororo yemamwe marudzi eeel yakaratidza kuti mhuka dzemubathypelagic dzakaita senge swallower eels uye bobtail snipe eels dzaive neruvara rwakanyanya-yakasviba sepelicans eels, nepo deepwater pelagic eels, senge snipe eels uye sawtooth eels, inogara mumvura isina kudzika ine dhigirii rakaderedzwa zvishoma. ye pigment iyi.
Munguva pfupi yapfuura, kekutanga, pelican eel yakatorwa pakhamera ine chikafu mudumbu rayo. Pasinei nekushayikwa kwekushambira, zvinofungidzirwa kuti zvisikwa izvi zvinoshandisa miswe yazvo yebioluminescent sechiredzo chekuredza kukwezva tumacrustaceans kana squid, izvo zvinozodya.
Iyo yakasviba pigmentation yezvikara izvi inoita kuti vashandise bioluminescence kuti vabatsire, zvichiita kuti matipi emuswe wepelican eels uye swallower eel aite seanopenya, anokwezva mabhekoni murima. Kana pelican eel yakwevera mhuka yayo pedyo zvakakwana, muromo wayo unogona kuwedzera zvakapetwa kashanu uye inomedza chinangwa chayo mugumbo rimwe chete.
Ghedotti akataura kuti zvakakosha pakukweva mhuka nechiedza kuti mhuka isaona kuvepo kwechikara kupfuura chambo. Pamusoro pezvo, kune nzira dzakasiyana siyana idzo bioluminescence inoshandiswa pakati pemhando dzakasiyana dzehove kunze kwekuishandisa kukwezva mhuka, uye muzhinji wezviitiko izvi, zvinonyanya kubatsira kana yako luminescence isingaratidze kuvepo kwezvimwe zvikamu zve. muviri wako.
Chidzidzo chacho chakatanga kubudiswa mumagazini Environmental Biology yeHove musi waJuly 18, 2023.
