The Chochitika cha monster USS Stein, nkhani yachinsinsi ndi yongopeka yomwe inachitika mu November 1978, ikupitirizabe kukopa chidwi cha anthu omwe ali ndi chidwi ndi zochitika zosamvetsetseka komanso kuya kwa nyanja. Kuwonaku kudachitika m'sitima ya USS Stein, gulu lankhondo lankhondo la United States lomwe likugwira ntchito yothandiza kumanga ma chingwe apansi pa nyanja ku Caribbean. Pamene ogwira ntchitowo anali kuchita ntchito zachizoloŵezi, cholengedwa chosadziwika chinatuluka pansi pa nyanja ndikuwononga kwambiri sitimayo, zomwe zinapangitsa kuti afotokoze mopupuluma ndi mikangano yomwe yakhala ikuchitika mpaka lero.
Chiphunzitso chimodzi chomveka chofuna kumveketsa bwino za zochitika zosamvetsetseka izi ndi polar gigantism or abyssal (deep-sea) gigantism. Lingaliro limeneli likutanthauza chodabwitsa chimene zamoyo m'madera otentha ndi nyanja zakuya zimasonyeza zazikulu-kuposa-zachibadwa masaizi chifukwa cha kuzizira kwambiri ndi magwero a chakudya chochuluka chopezeka m'maderawa. Ndizodziwika bwino kuti mitundu ingapo m'madera otere imawona kukula kwakukulu chifukwa cha mikhalidwe yabwinoyi. Kodi chilombo cha USS Stein chikanakhala chitsanzo cha gigantism ya polar?
Popeza pali umboni wocheperako komanso kusakhalapo kwa kafukufuku wotsimikizika wasayansi, ziganizo zotsimikizika ndizovuta kupeza. Komabe, ochirikiza chiphunzitso cha polar kapena abyssal gigantism amanena kuti chilombo cha USS Stein chikhoza kukhala chamoyo chosadziwika, mwinamwake chilombo chakuya chakuya chomwe chikukula kwambiri chifukwa cha chilengedwe chomwe chili m'madzi akuya a Caribbean.
Komanso, kutalikirana ndi kukula kwa nyanja kumapangitsa kukhulupirira kuti zolengedwa zosiyanasiyana zosadziŵika zidakali pansi pa dziko lapansili. Chochitika cha chilombo cha USS Stein chimalimbikitsa lingaliro lakuti zamoyo zambiri zam'madzi sizidziwika kwa ife. Kukumana kodabwitsa kumeneku kumakhala chikumbutso chakuti chidziŵitso chathu cha nyanja zamchere zapadziko lapansi, ngakhale kuti n’chachikulu, sichinakwaniritsidwebe.
Ngakhale chochitika cha monster USS Stein chili pakati pa zinsinsi zodziwika bwino za mbiri yakale, chikupitilirabe kusangalatsa komanso kukopa akatswiri komanso okonda chimodzimodzi. Kuthekera kwa polar kapena abyssal gigantism kumapereka kufotokozera kochititsa chidwi, kuwonetsa zodabwitsa ndi kuya kosawerengeka kwa chilengedwe pomwe amatikumbutsa kuti dziko lathu lapansi likadali ndi zinsinsi zomwe zikudikirira kuti ziwululidwe. Pamapeto pake, chikhalidwe chenicheni cha cholengedwa chowoneka bwinochi chingakhale chobisika kosatsimikizika, kusiya malo amalingaliro ndi malingaliro kuti aziyendayenda m'nyanja zazikulu za malingaliro athu.
Pambuyo powerenga za nkhani yodabwitsa ya chilombo cha USS Stein, werengani za kuthekera kwa chitukuko chanzeru cha m'madzi.
