Saber-toot kapena tiger moray eel (lat. Achina achiyina) ndi nsomba yayikulu yam'madzi yochokera ku mtundu wa Enchelycore wa banja la a Murenov (lat. Muraenidae), yemwe amakhala m'madzi ofunda a kum'mawa kwa Atlantic.

Ma Moray eels ndi odziwika chifukwa chokonda komanso kuchita nkhanza kwambiri, osaganizira kwenikweni kuti angagwire aliyense wolakwira mtendere wawo, ngakhale atakhala kuti ndi wamkulu kuposa iwo. Koma ngati ambiri mwa omwe akuyimira banjali sangathe kuwononga mdani, ndiye kuti E. anatina, wokhala ndi nsagwada yoopsa, amatha kuthyola zidutswa zilizonse zolimbikitsa.

Pakamwa pa nyama zowopsa zam'madzi zoterezi pamadontho amakhala ndi mano owongoka ngati singano. Ena mwa mano ndi akuthwa komanso aatali: pafupifupi 25 mm, enawo ndi ofupikirapo komanso ndi akulu. Ziwerengero zawo zimatha kusiyanasiyana pang'ono m'magulu osiyanasiyana, chifukwa ma fangawo samakula m'mizere koma paliponse kumtunda komanso kumtunda kwa pakamwa. Mafangawa amawonekera kwambiri kotero kuti zitha kuwoneka ngati anapangidwa ndi galasi, koma palibe kukayikira m'mphamvu zawo - nsomba zimagwira mosavuta nkhanu zomwe zimatetezedwa ndi chipolopolo chambiri komanso chobisidwa mumazipolopolo.

Mawonekedwe

Kutalika kwa nyama yolusa ya nyalugwe kumayambira 80 mpaka 120 masentimita, komwe sikuli kwa nthawi yayitali kwambiri, ngakhale kukumbukira chimphona cha Gymnothorax javanan ndi Strophidon sathete, yemwe kutalika kwake kumafika mpaka 3 ndi 4 metres, motero, ndi kulemera pafupifupi makilogalamu 30.

Chifukwa chomwe amachitcha nyanjayi ndizodabwitsa kwambiri kwa nthawi yayitali: mikwingwirima yakuda imabalalika chifukwa cha thupi lowoneka ngati nsombayo chimodzimodzi ndofanana ndi woimira mphaka wa dzinalo. Munjira zina zonse, ma eel omwe ali ndi mawonedwe ofunda ali ofanana kwambiri ndi abale awo: thupi lalitali lokometsedwa kumbali, kusakhalitsa mamba ndi zipsepse, maso akuda opanda kanthu komanso nsagwada ya pharyngeal iwiri ya Hans Giger.

Dera

E. anatina amakhala m'matanthwe a Nyanja ya Atlantic m'mphepete mwa zisumbu: Canary, Azores, Maidera, St. Helena, Cape Verde ndi gombe la Mediterranean la Israeli. Amakonda madzi ofunda okhala ndi mitundu yambiri ya nyama, motero samakonda kuzama kuzama. Nthawi zambiri, amatha kupezeka m'miyala yopapatiza yamiyala akuya kwa mamita atatu mpaka 20, kawirikawiri mpaka 60 metres.

Ribbon moray eel (lat. Rhinomuraena quaesita) ndi nsomba yolambira panyanja yochokera ku banja la a Mureenidae la dongosolo la Anguilliformes. Amadziwikanso kuti nosed moray, riboni wabuluu kapena eel-strip wakuda.

Cholinga cha Kusintha Kwa Kugonana

Chizindikiro cha cholengedwa ichi ndi chikondi cha kugonana ndi mitundu. Amuna achichepere ndi utoto wakuda. Popeza ndi okhwima, amatembenukira buluu. Atsikana obiriwira amakhala achikasu ndi ukalamba.

Kutalika kwa thupi kukafika pa 90-95 masentimita, kusokonekera kwa msambo kumasintha nthawi zambiri pogonana.

Amuna ndi achangu kwambiri pankhaniyi. Akadzakhala akazi, mtundu wawo umasintha pang'onopang'ono kuchoka pabuluu kukhala chikaso. Chosangalatsa ndichakuti, ali mu ukapolo, nsomba, monga lamulo, zimasiya chidwi ndi kusintha koteroko ndikusungabe kukhulupirika kwawo.

Izi zidapezeka mu 70s yokha ya zaka makumi awiri. Izi zisanachitike, nsomba pamitundu yosiyanasiyana yakukula kwawo zidalembedwa ndi mitundu yosiyanasiyana.

Kugawa ndi chikhalidwe

Ma tape moray eels amakhala m'madzi a Indian Ocean kuyambira pagombe la East Africa kupita kum'mwera kwa Japan, Islands Islands, Marshall ndi French Polynesia. Amakhala m'matanthwe a coral ndi m'madzi amchenga opita mpaka 50 m.

Pafupifupi nthawi yonseyi nsomba imakhala pobisalira, pomwe mutu wake umangokhala.

Thupi limakhala lodzaza ndi ma bactericidal mucus, omwe amalilola kuti lizilowa mosavuta pazovala zazing'ono kwambiri popanda kuwopa kuvulala kwamtundu uliwonse. Slime imathandizanso matepi amodzi kulimbitsa makhoma awo ngati ali mumchenga. Sadzimanganso, koma amangogwiritsa ntchito nyumba zotsalazo za anthu ena okhala pansi pamadzi.

Chakudyacho chimakhala ndi nkhanu zazing'ono komanso nsomba. Tape moray eel imakhala ndi fungo labwino kwambiri. Chiwalo chogwiritsa ntchito molumikizana chili ndi zotseguka zinayi zammphuno, zomwe awiri oyambayo ndi wamba, ndipo chachiwiri chimafanana ndi timapepala ta mawonekedwe. Mukawatseka, nyama yolusa imataya mwayi wopeza chakudya, chifukwa kusaka kumachitika usiku, pamene masomphenya sachita mbali yapadera.

Nsomba zimangokhala payokha ndikuwonetsa chiwawa poyanjana ndi abale. Ndiosowa kwambiri kuti amakhala m'magulu awiriawiri, kuwonerera ndale.

Kuswana

Mawonekedwe a tepi moray eels amaphunziridwa bwino. Kutumphuka kumakhulupirira kuti kumachitika m'madzi osaya mkati mwa miyezi yozizira. Caviar imayandama momasuka pamadzi pazama plankton. Kuchokera ku caviar, mphutsi zotchedwa leptocephels zimabadwa. Amakhala ndi mitu yozungulira komanso zipsepse zokuzungulira. Thupi limawonekera ndipo pakubadwa silidutsa 10 mm.

Mphutsi zimatha kunyamulidwa ndi mafunde am'nyanja pamaulendo ataliatali. Wowongolera nthawi zina amakhala mpaka miyezi 8-10, pambuyo pake leptocephalus imakula ndikusankha malo okhalamo. Ribbon moray eels amakhala okhwima pofika zaka 4-6.

Kufotokozera

Thupi ndi lalitali kwambiri, njoka, kutalika kwa masentimita 130. Pakamwa, zipsepse ndi maso ake ndi achikaso. Mtundu umasiyana ndi jenda komanso zaka. Mphuno zam'maso zimapezeka pazomwe zimapangidwa ndi masamba, ndi zam'mbuyo pafupi ndi maso. Pansipa yam'munsi pali njira zitatu zofanana ndi ndevu.

Kutalika kwa moyo wamatayala amisala pafupifupi zaka 10.
