I-Japanese dwarf squid (Idiosepius paradoxus) ingeyesigaba se-cephalopod, uhlobo lwama-molluscs.
Ukusatshalaliswa kwe-squid encane yaseJapan.
Isigaxa esincane saseJapan sisatshalaliswa entshonalanga yePacific Ocean, emanzini aseJapan, eSouth Korea naseNyakatho ye-Australia. Itholakala eduze kwe-Indonesia kanye ne-Pacific Ocean ukusuka eSewula Africa kuye eJapan kanye ne-South Australia.
Indawo ye-squid encane yaseJapan.
I-Japanese pygmy squid iyinhlobo ye-benthic etholakala emanzini angajulile, asogwini.
Izimpawu zangaphandle ze-squid yaseJapan.
Isigaxa esincane saseJapan singesinye sezingwane ezincane kunazo zonke, ngengubo yaso sikhula size sifike ku-16 mm. Izinhlobo ezincane kakhulu zama-cephalopods. I-squid encane yaseJapan iyahluka ngombala nosayizi, nabesifazane ababa nobude obusuka ku-4.2 mm kuye ku-18.8 mm. Isisindo singama-50 - 796 mg. Abesilisa bancane, ubukhulu bomzimba wabo buhluka kusuka ku-4.2 mm kuye ku-13.8, nobukhulu bomzimba busuka ku-10 mg kuye ku-280 mg. Lezi zinhlamvu zishintsha nezinkathi zonyaka, njengoba ama-cephalopods alezinhlobo abonwa izizukulwane ezimbili ngonyaka.
Ukuzalela ama-squid amancane aseJapan.
Phakathi nenkathi yokuzalanisa, ingulube encane yaseJapane ikhombisa izimpawu zokuqomisana, ezibonakala ngokushintsha kombala, ukunyakaza komzimba, noma ukusondelana. Abesilisa bahlangana nabalingani abangahleliwe, kwesinye isikhathi basebenze ngokushesha okukhulu kangangokuthi baphuthume abanye besilisa ngabesifazane bese bedlulisela amangqamuzana abo amagciwane emzimbeni wesilisa. Ukukhwelana kwenzeka ngesikhathi se-oviposition. Umanyolo ungaphakathi. Esinye sezibopho ze-squid sinesitho esikhethekile ekugcineni, sifinyelela emgodini womzimba wesifazane futhi sidlulisele amaseli wegciwane. Phakathi nenyanga, owesifazane ubeka amaqanda angama-30-80 njalo ezinsukwini ezi-2-7, ezigcinwa isikhashana esithweni sakhe sangasese.
Ukutshala kusuka ekupheleni kukaFebhuwari kuya maphakathi noMeyi futhi kusuka ngoJuni kuya ngasekupheleni kukaSepthemba.
Emvelweni wawo wemvelo, amaqanda abekwa endaweni eyisicaba endaweni engezansi. Ama-squid amancane aseJapan awanaso isigaba sesibungu, akhula ngqo. Abantu abasha ngokushesha banomlomo onamazinyo - lolu phawu luvela kubo kusenesikhathi, uma kuqhathaniswa namanye ama-cephalopods, lapho kutholakala khona uqhwaku olumunyu ngezinhlobo zesibungu. Ama-squid amancane aseJapan anempilo yokuphila kwezinsuku eziyi-150.
Isikhathi esifushane sokuphila cishe sihlobene namazinga okushisa aphansi amanzi lapho umzimba ukhula khona. Izinga lokukhula eliphansi liyabonakala emanzini abandayo. Abesilisa bavuthwa ngokushesha kunabesifazane ngezikhathi ezibandayo nezifudumele. Ama-squid amancane aseJapan anika izizukulwane ezimbili ezinobukhulu obuhlukile babantu. Ngenkathi efudumele bavuthwa ngokocansi ngokushesha okukhulu, ngenkathi epholile bayakhula ebusika, kepha bafinyelela eminyakeni yokuzala kamuva. Lezi squid ezincane zivuthwa ngokocansi ezinyangeni eziyi-1.5-2.
Ukuziphatha kwe-squid yaseJapan emifushane.
Ama-squid amancane aseJapan ahlala eduze nogu futhi acasha emiqamelweni yezitshalo zasolwandle noma ezasolwandle. Zinamathiselwe ekusekelweni ngeglu ephilayo enamathela ngemuva. I-squid yemifino ingashintsha umbala, ukwakheka nokuthungwa komzimba. Lezi zinguquko zingasetshenziswa ukuxhumana omunye nomunye futhi njengokufihla lapho kunesidingo sokubalekela izilwane ezidla ezinye. Emvelweni wamanzi, baqondiswa ngosizo lwezitho zombono. Umuzwa othuthukisiwe kakhulu wephunga usiza empilweni ye-benthic ku-algae.
Ukudla i-squid encane yaseJapan.
I-squid encane yaseJapane idla ama-crustaceans omndeni we-gammarida, ama-shrimps ne-mysids. Ihlasela izinhlanzi, kanti i-squid encane ivame ukudla imisipha kuphela futhi ishiye amathambo ephelele, njengomthetho, wonke amathambo. Inhlanzi enkulu ayinakhubazeka ngokuphelele, ngakho-ke yeneliseka ngengxenye kuphela yento ebanjwayo.
Indlela yokuzingela iqukethe izigaba ezimbili: esokuqala - umhlaseli, okubandakanya ukulandela umkhondo, ukulinda nokubamba isisulu, bese kuthi esesibili - sidle isisulu esibanjiwe.
Lapho i-pygmy squid yaseJapane ibona inyamazane yayo, iyalwela, iphonsela ngaphandle igobolondo le-crustacean.
Isondela ebangeni lokuhlaselwa elingaphansi kuka-1 cm.I-squid yaseJapan ihlasela ngokushesha okukhulu bese ibamba inyamazane lapho kuhlangana khona ikhava e-chitinous nengxenye yayo yokuqala yesisu, iphokophele phambili kwesinye sezintambo.
Ngezinye izikhathi ama-squid amancane aseJapane ahlasela inyamazane ephindwe kabili ubukhulu bayo. I-squid emfushane ikhubaza imfanzi ngomzuzu owodwa isebenzisa into enobuthi. Ubamba inyamazane endaweni efanele, uma kungenjalo isisulu ngeke sikhubazeke, ngakho-ke i-squid kufanele ibambe ngendlela efanele. Uma kukhona ama-crustaceans amaningi, ama-squid amaningi aseJapan angazingela ngasikhathi sinye. Imvamisa, umhlaseli wokuqala udla ukudla okuningi. Ibamba inyamazane, isigaxa esincane saseJapane sibhukuda sibuyele emuva kulwelwe ukuze siqede inyamazane ngomoya ophansi.
Ngemuva kokubamba i-crustacean, ifaka imihlathi yayo enjenge-horny ngaphakathi bese iyinyakazisa nxazonke.
Ngasikhathi sinye, i-squid igwinya izingxenye ezithambile ze-crustacean bese ishiya i-exoskeleton ingenalutho futhi iphelele. Ikhava le-chitinous eliqinile libukeka sengathi i-crustacean imane yaphela. I-exoskeleton ye-mysid ivame ukukhishwa kungakapheli imizuzu eyi-15, ngenkathi inyamazane enkulu ingadliwa iphelele, futhi ngemuva kokudla, i-chitin ihlala ezinsaleleni zenyama enamathele ku-exoskeleton.
I-squid encane yaseJapan ngokuyinhloko igaya ukudla ngaphandle. Ukugaya ukudla kwangaphandle kwenziwa lula ngomlomo onosizi, oqala ugaye inyama ye-crustacean, bese i-squid imunca ukudla, yenza lula ukugayeka ngokwenza kwe-enzyme. Le enzyme inikelwe futhi ikuvumela ukuthi udle ukudla okugaywe kancane.
Indima ye-ecosystem ye-Japanese pygmy squid.
Ama-squid amancane aseJapan asezingeni lezinto eziphilayo zasolwandle nasolwandle ayingxenye yochungechunge lokudla, adla ama-crustaceans nezinhlanzi, futhi wona, adliwa yizinhlanzi ezinkulu, izinyoni, izilwane ezincelisayo zasolwandle namanye ama-cephalopods.
Okusho umuntu.
Ama-squid amancane aseJapan avunwa ngezinhloso zesayensi. Lawa ma-cephalopods ayizifundo ezinhle zocwaningo lokuhlola ngoba anempilo emfushane, aphila kalula e-aquarium, futhi azalela ekuthunjweni. Ama-squid amancane aseJapan njengamanje asetshenziselwa ukutadisha ukukhiqizwa kanye nezinto ezihlukile zokusebenza kohlelo lwezinzwa; ziyizinto ezibalulekile zokutadisha izinkinga zokuguga nokudluliswa kwezici zofuzo.
Isimo sokonga se-Japanese pygmy squid.
Ama-squid amancane aseJapan akhona ngobuningi bawo ezilwandle nasolwandle, ayasinda futhi azalane ezindaweni zasemanzini ezinosawoti. Ngakho-ke, i-IUCN ayihlolwe futhi ayinaso isigaba esikhethekile.
