I-cuttlefish eqhakazayo (i-Metasepia pfefferi) noma i-cuttlefish kaPfeffer ingeyesigaba se-cephalopod, uhlobo lwama-molluscs.
Ukusatshalaliswa kwe-cuttlefish enezimbali.
I-cuttlefish eqhakazayo isatshalaliswa esifundeni esishisayo i-Indo-Pacific Ocean. Kutholakala ikakhulukazi ngasogwini lwaseNyakatho ne-Australia, eNtshonalanga Australia, nasengxenyeni eseningizimu yePapua New Guinea.
Izimpawu zangaphandle ze-cuttlefish enezimbali.
I-cuttlefish enezimbali iyi-cephalopod mollusk encane, ubude bayo busuka kumasentimitha ayi-6 kuye kwayi-8. Insikazi inkulu kunowesilisa. Bonke abamele iMetasepia banezinhliziyo ezintathu (izinhliziyo ezimbili zegill kanye nesitho esiyinhloko sokujikeleza kwegazi), uhlelo lwemizwa oluyindandatho, negazi eliluhlaza okwesibhakabhaka eliqukethe izingxube zethusi. I-cuttlefish enezimbali ihlome ngamatende abanzi ayi-8 lapho kunemigqa emibili yamaswidi. Ngaphezu kwalokho, kunamatende amabili okubamba, afana namathiphu "amakilabhu".
Ingaphezulu lezintambo zokubamba libushelelezi kulo lonke ubude, futhi emaphethelweni kuphela lapho linamaswidi amakhulu khona. I-cuttlefish enezimbali inombala onsundu ngombala. Kepha kuya ngesimo, imizimba yabo ithatha imibala emhlophe nephuzi, futhi izintambo ziba nsomi ngokubomvana.
Isikhumba sama-cephalopods siqukethe ama-chromatophores amaningi anamaseli e-pigment, i-cuttlefish eqhakazayo engakwazi ukuwasebenzisa kalula ngokuya ngemvelaphi yendawo.
Abesifazane nabesilisa banemibala efanayo yombala, ngaphandle kwenkathi yokukhwelana.
Umzimba we-cuttlefish umbozwe ngengubo ebanzi kakhulu, e-oval, ethambekele ohlangothini lwe-dorsoventral. Ehlangothini langemuva lesembatho, kunamabhangqa amathathu amakhulukazi, ayisicaba, amachashazi e-papillary amboza amehlo. Ikhanda licishe kancane kunengubo yonke. Ukuvulwa komlomo kuzungezwe yizinqubo eziyishumi. Kwabesilisa, i-hentocotylus eyodwa iguqulwa ibe yi-hectocotylus, edingekayo ekugcineni nokuhambisa i-spermatophore kowesifazane.
Ukuguqulwa kombala ku-cuttlefish yezimbali.
Izimbali ze-cuttlefish zigcina ikakhulu ku-substrate enosilika. Amagquma anamagquma emfucumfucu ehleliwe yemvelo acebile ngezinto eziphilayo ezidla i-cuttlefish. Endaweni enjalo, ama-cephalopods abonisa ukufihla okumangalisayo okubavumela ukuthi bacishe bahlangane ngokuphelele kumbala wezidliwayo.
Uma kusongela impilo, i-flowertle cuttlefish ishintsha imibala ethulisiwe ibe amathoni akhanyayo ansomi, aphuzi, abomvu.
Ukushintsha umbala osheshayo kuncike ekusebenzeni kwezitho ezikhethekile ezibizwa ngama-chromatophores. Isenzo se-chromatophores silawulwa yisistimu yezinzwa, ngakho-ke umbala womzimba wonke ushintsha ngokushesha okukhulu ngenxa yokuncipha kwemisipha esebenza ekhonsathini. Amaphethini anemibala ahamba wonke umzimba, kwakheka inkohliso yesithombe esihambayo. Zibalulekile ekuzingeleni, ekuxhumaneni, ekuvikeleni futhi ziyisithunzi esithembekile. Ngasohlangothini lwengubo yesiphetho, imivimbo eluhlaza okwesibhakabhaka ivame ukugxisha ezindaweni ezimhlophe, lezo zinto zombala zanikeza lolu hlobo igama elithi "flower cuttlefish". Le mibala ekhanyayo isetshenziselwa ukwazisa ezinye izidalwa ngezinto ezinobuthi zala ma-cephalopods. Lapho ihlaselwa, i-cuttlefish enezimbali ayishintshi umbala isikhathi eside futhi ivayizisa izintambo zayo, ixwayisa isitha. Njengecebo lokugcina, bavele babaleke, badedele ifu likayinki ukuphazamisa umhlaseli.
Indawo yokuhlala ye-cuttlefish enezimbali.
I-cuttlefish enezimbali ihlala ekujuleni kwamanzi kusuka kumamitha ama-3 kuye kwangama-86. Uncamela ukuhlala phakathi kwezihlabathi ezinesihlabathi nodaka emanzini asezindaweni ezishisayo.
Ukukhiqizwa kabusha kwe-cuttlefish yezimbali.
Izimbali ze-cuttlefish dioecious. Abesifazane bavame ukukhwelana nabesilisa abangaphezu koyedwa.
Abesilisa phakathi nenkathi yokuzalanisa bathola imibala enemibala eheha abesifazane.
Abanye besilisa bangashintsha umbala babukeke njengabesifazane ukuze bagweme owesilisa onolaka kakhulu, kepha basondele eduze kowesifazane ngokukhwelana.
Ku-cuttlefish eqhakazayo, ukukhulelwa kwangaphakathi. Abesilisa banesitho esikhethekile, i-hectocotyl, esetshenziselwa ukugcina nokuthwala ama-spermatophores (amaphakethe wesidoda) esifundeni sebuccal sabesifazane ngesikhathi sokukhwelana. Insikazi ibamba ama-spermatophores ngama-tentacles bese iwabeka emaqandeni. Ngemuva kokukhulelwa, insikazi izalela amaqanda ngesikhathi esisodwa emifantwini nasemifantwini yolwandle ukuze icashe futhi ivikele ezilwaneni ezizingelayo. Amaqanda amhlophe futhi awazungezi ukuma; ukukhula kwawo kuncike ekushiseni kwamanzi.
I-cuttlefish yabantu abadala ayinakekeli inzalo; abesifazane, lapho bebeka amaqanda abo ezindaweni ezifihlekile, bafa ngemuva kokuzala. Isikhathi sokuphila se-cuttlefish eziqhakazayo emvelweni sisukela ezinyangeni eziyi-18 kuye kwezingu-24. Lolu hlobo lwe-cuttlefish aluvamile ukugcinwa ekuthunjweni, ngakho-ke, indlela yokuziphatha ekuthunjweni ayichazwanga.
Ukuziphatha kwe-cuttlefish enezimbali.
Izimbali ze-cuttlefish ziyabhukuda kancane uma kuqhathaniswa namanye ama-cephalopods afana ne-squid. "Ithambo" langaphakathi lisetshenziselwa ukulawula ukusimama ngokulawula ukucindezela kwegesi noketshezi olungena emagumbini akhethekile e-cuttlefish. Njengoba "ithambo" lincane kakhulu maqondana nengubo, i-cuttlefish ayikwazi ukubhukuda isikhathi eside kakhulu futhi "ihambe" ngezansi.
I-cuttlefish enezimbali inamehlo athuthuke kakhulu.
Bayakwazi ukubona ukukhanya okuhlukanisiwe, kepha umbono wabo awunambala. Emini, i-cuttlefish enezimbali izingela inyamazane.
I-Cuttlefish inobuchopho obuthuthuke kahle, kanye nezitho zokubona, ukuthinta nokuzwa kwamagagasi omsindo. I-cuttlefish ishintsha umbala uma isabela endaweni ezungezile, kungaba ukuheha isisulu noma ukugwema izilwane ezizingelayo. Amanye ama-cuttlefish akwazi ukuzulazula ngokusebenzisa ama-visual tinch.
Ukondla i-cuttlefish enezimbali.
I-cuttlefish enezimbali yizilwane ezidla ezinye. Zondla kakhulu ama-crustaceans nezinhlanzi ezinamathambo. Ngenkathi ibamba inyamazane, i-cuttlefish enezimbali ilahla ngokucijile izintambo phambili bese ibamba isisulu, bese siyiletha "ezandleni" zabo. Ngosizo lomlomo nolimi olufana noqhwaku - i-radula, efana nebhulashi locingo, i-cuttlefish imunca ukudla ezingxenyeni ezincane. Izingcezu zokudla ezincane zibaluleke kakhulu ekondleni, ngoba isisu se-cuttlefish ngeke sikwazi ukuphuthelwa inyamazane enkulu kakhulu.
Okusho umuntu.
I-cuttlefish eqhakazayo ingenye yama-cephalopods amathathu anobuthi aziwayo. Ubuhlungu be-Cuttlefish bunemiphumela efanayo ebulalayo njenge-toxin enezintambo eziluhlaza okwesibhakabhaka. Le nto iyingozi kakhulu kubantu. Ukwakheka kwe-toxin kudinga ukutadisha okuningiliziwe. Mhlawumbe izothola ukusetshenziswa kwayo kwezokwelapha.
Isimo sokongiwa kwe-cuttlefish enezimbali.
I-cuttlefish enezimbali ayinaso isimo esikhethekile. Kunolwazi oluncane kakhulu ngempilo yala ma-cephalopods endle.
