Ku isihloko esandulele sikhulume nge indlela ethile abahamba ngayo nokuthi baqoqana kanjani lapho bedinga ukuzingela. Namuhla sizoqhubeka nokuhlola okwengeziwe nge-sailfish ehehayo, sihlukanisa izici zayo eziyinhloko, indawo yokuhlala, ukudla, ilukuluku kanye nendima yazo ekudobeni kwezemidlalo.
Izici eziyinhloko ze-sailfish
I-sailfish (ogama lakhe lesayensi I-Istiophorus platypterus) ibhekwa njengenye yezinhlanzi ezinhle kakhulu nezishesha kakhulu olwandle. Isici sayo esigqama kakhulu yisona i-dorsal fin enkulu esimweni sikaseyili, sakhiwe izakhi ezingu-37 kuya kwezingu-49. Iphinde ibe ne- dorsal fin yesibili encane kanye nomhlathi wangaphezulu omude nocijile ofana ne-swordfish.
Le nhlanzi ingafinyelela a ubukhulu bufika kumamitha amathathu yinde futhi inesisindo esingaphezu kwamakhilogremu ayi-100, kanti i-Pacific sailfish ivamise ukudlula amakhilogremu angama-90. Umzimba wayo uyi-hydrodynamic, eyivumela ukuthi ifinyelele isivinini esifinyelela phezulu Amakhilomitha angama-109 ngehora, iyibeka njengenye yezinhlanzi ezisheshayo olwandle.
Elinye iqiniso elithakazelisayo yindlela yabo yokuphila engaziwa kangako. I-Sailfish ivamise ukuhamba ngamaqembu, ikakhulukazi lapho izingela, isebenzisa ukushesha nesivinini sayo ukuze izungeze futhi ibambe inyamazane yayo. Ubude bokuphila kwabo bufushane ngokumangalisayo, abufinyeleli kalula Iminyaka emi-4 ngokwesilinganiso, encishisiwe ngokuphawulekayo uma iqhathaniswa nezinye izinhlobo zobukhulu obufanayo.
Indawo yokuhlala nokusatshalaliswa
I-sailfish iwuhlobo olusatshalaliswe kabanzi oluhlala kulo izilwandle ezishisayo nezishisayo ezivela emhlabeni wonke, kuhlanganise Atlantic, Pacific nolwandle Indian. Incamela amanzi afudumele anamazinga okushisa aphakathi kuka-21 no-30 degrees Celsius, nakuba ibonisa ikhono elimangalisayo lokuzivumelanisa nezimo zezulu ezihlukene.
Ngokuvamile kutholakala kokubili ku izindawo ezisogwini namanzi olwandle, ukuvama kwezingqimba ezingaphezulu eduze nendawo, nakuba ubukhona bayo buqoshwe kuze kufike kumamitha angu-350 ukujula. Ngezinyanga ezifudumele, ithuthela ezindaweni eziphakeme ifuna ukudla nezimo ezifanele.
Ukudla
I-sailfish iyisilwane esidliwayo esinemenyu ehlanganisa kakhulu izinhlanzi ezincane, njengama-sardine nama-anchovies, kanye nesquid namanye ama-cephalopod. Isebenzisa umhlathi wayo ongaphezulu obude njenge "harpoon" ukuze ibambe inyamazane yayo, ikwenze kube lula ukuyibamba. Le nqubo, kuhlanganiswe nesivinini namandla akhe, imenza umzingeli onekhono kakhulu.
Kwezinye izifunda, njengeGulf of Mexico kanye neCaribbean, kubonakala kuxosha izikole de peces, ngokuvamile ebaqondisa ezindaweni lapho ukufinyelela kokubaleka kulinganiselwe.
I-Sailfish curiosities
Esinye sezici ezithakazelisa kakhulu ze-sailfish injongo ye- dorsal fin yayo enkulu. Nakuba umsebenzi wawo oqondile ungaziwa, ososayensi baye babeka imibono eminingana. Ingase isetshenziselwe gcina ukuzinza futhi enze amasu asheshayo, alawule izinga lokushisa lomzimba wawo lapho ebekwe elangeni noma abonakale emakhulu futhi avimbele izilwane ezidla ezinye ezingase zibe khona.
Ivamise ukudidaniswa nezinhlobo ezifana ne-marlin noma i-swordfish, ehlanganyela ngayo ngokufana okuthile ngokomzimba, kodwa ingeyomndeni wakwa-Istiophoridae, ohlukile kulowo we-swordfish (Xiphiidae).
I-Sailfish ekudobeni kwezemidlalo
I-Sailfish iyi-a isithonjana sokudoba ezemidlalo ngenxa yamandla azo, isivinini kanye nekhono lokugxuma okumangalisayo emanzini, okubonisa inselele enkulu kubadobi. Basebenzisa amasu anjengokuhambahamba ngezidlalo ezibukhoma noma zokwenziwa, njengezimpaphe noma izinkezo, ukuze bahehe ukunaka kwakho.
Nakuba inyama yayo ingaziswa kakhulu emkhakheni wokupheka, ukuthunjwa kwayo kufanekisela indondo ebalulekile. Kodwa-ke, ngenxa yokukhathazeka okukhulayo ngokulondolozwa kwalolu hlobo, ukubamba okuningi ekudobeni kwezemidlalo kwenziwa ngaphansi kwendlela "yokubamba nokukhulula".
I-Sailfish iyaqhubeka imangaza ososayensi kanye nabathandi bokuzilibazisa ngokufanayo. Ijubane layo elimangalisayo, elihlanganiswe nekhono layo eliyingqayizivele lemvelo kanye namakhono okuzingela, liyibeka njengombukwane wangempela wasolwandle ongawubuka.
