PAR\u00cd\u017d – V\u00fdskumn\u00edci s pomocou ponorky objavili na dne oce\u00e1nu pri Galap\u00e1goch doteraz nezn\u00e1mu chobotnicu, modr\u00fa ako oce\u00e1n a ve\u013ek\u00fa nanajv\u00fd\u0161 ako golfov\u00e1 lopti\u010dka. \u201eJe mali\u010dk\u00e1! Je modr\u00e1!\u201c povedala vedky\u0148a potom, ako zachytili az\u00farov\u00e9ho hlavono\u017eca na z\u00e1bere pren\u00e1\u0161anom z ponorky. Informovala o tom agent\u00fara AFP.<\/p>\n
T\u00edm vedcov z Charles Darwin Foundation na\u0161iel nov\u00fd druh chobotnice pribli\u017ene 1800 metrov pod hladinou mora, uv\u00e1dza sa vo v\u00fdskume zverejnenom v pondelok. \u201eHne\u010f som vedela, \u017ee ide o nie\u010do naozaj v\u00fdnimo\u010dn\u00e9,\u201c povedala odborn\u00ed\u010dka na chobotnice Janet Voightov\u00e1, ktor\u00fa po\u017eiadali o identifik\u00e1ciu zvl\u00e1\u0161tneho druhu. K dispoz\u00edcii mala spo\u010diatku len fotografie \u017eivo\u010d\u00edcha. Nesk\u00f4r jej doru\u010dili aj zachovan\u00fd exempl\u00e1r. Zaujal ju okam\u017eite, lebo najbli\u017e\u0161ia zn\u00e1ma pr\u00edbuzn\u00e1 tohto tvaru chobotnice \u017eije pri pobre\u017e\u00ed Uruguaja, teda v inom oce\u00e1ne na opa\u010dnej strane Ju\u017enej Ameriky.<\/p>\n
Pri novom druhu chobotnice sa zvy\u010dajne rozre\u017ee, aby bolo mo\u017en\u00e9 presk\u00fama\u0165 jednotliv\u00e9 \u010dasti tela. To v\u0161ak neplatilo v tomto pr\u00edpade. \u201eMali sme len jeden exempl\u00e1r, tak\u017ee som ho nechcela rozobera\u0165,\u201c povedala Voightov\u00e1. Jej t\u00edm preto pou\u017eil CT skenovanie, ktor\u00e9 vytvorilo tis\u00edce r\u00f6ntgenov\u00fdch sn\u00edmok, a tie n\u00e1sledne spojili do 3D modelu chobotnice, \u010d\u00edm odhalili jej vn\u00fatorn\u00fa stavbu. \u201eNie je ni\u010d lep\u0161ie ako pre\u017ei\u0165 de\u0148 pozeran\u00edm sa na nie\u010do, \u010do e\u0161te \u017eiadny in\u00fd \u010dlovek nikdy nevidel,\u201c uviedla ved\u00faca r\u00f6ntgenov\u00e9ho laborat\u00f3ria Stephanie Smithov\u00e1.<\/p>\n
Nov\u00fd druh s n\u00e1zvom Microeledone galapagensis vynik\u00e1 nielen svojou modrou farbou, ktor\u00e1 je pova\u017eovan\u00e1 za jednu z najvz\u00e1cnej\u0161\u00edch v pr\u00edrode. Hlavono\u017eec je toti\u017e ak\u00fdmsi \u201etrpasl\u00edkom\u201c z \u010de\u013eade Megaleledonidae, ktorej z\u00e1stupcovia b\u00fdvaj\u00fa zvy\u010dajne ove\u013ea v\u00e4\u010d\u0161\u00ed a \u017eij\u00fa v Ju\u017enom oce\u00e1ne okolo Antarkt\u00eddy.\u00a0\u201eJej kr\u00e1tke, zavalit\u00e9 ch\u00e1padl\u00e1 s jedin\u00fdm radom pr\u00edsaviek ju odli\u0161uj\u00fa od v\u00e4\u010d\u0161iny chobotn\u00edc, ktor\u00e9 pozn\u00e1me,\u201c povedala Voightov\u00e1. Aj medzi podobn\u00fdmi druhmi ju odli\u0161uje sfarbenie a hladk\u00e1 ko\u017ea na chrbte. K\u00fdm na chrbte je svetlomodr\u00e1, na spodnej strane je \u201esilno tmavofialov\u00e1\u201c, uviedla odborn\u00ed\u010dka.<\/p>\n
\u201eMysl\u00edme si, \u017ee toto sfarbenie ju pom\u00e1ha chr\u00e1ni\u0165. Ak chobotnica uchop\u00ed koris\u0165, ktor\u00e1 vy\u017earuje svetlo, m\u00f4\u017ee to pril\u00e1ka\u0165 pred\u00e1torov, ktor\u00ed by potom mohli zjes\u0165 aj ju samotn\u00fa,\u201c vysvetlila. \u201ePreto chobotnica zakryje koris\u0165 svojou tmavou blanou, \u010d\u00edm sa chr\u00e1ni,\u201c dodala. Nie je ni\u010d nezvy\u010dajn\u00e9 objavi\u0165 nov\u00e9 druhy chobotn\u00edc v hlbokom mori \u2013 najm\u00e4 v oblastiach, ktor\u00e9 boli doteraz m\u00e1lo presk\u00faman\u00e9, \u010do je obrovsk\u00e1 \u010das\u0165 oce\u00e1nskeho dna. Voightov\u00e1 vrav\u00ed, \u017ee naposledy videla nov\u00fd druh chobotnice v roku 2023 pri pobre\u017e\u00ed Kostariky.<\/p>\n","protected":false},"excerpt":{"rendered":"PAR\u00cd\u017d – V\u00fdskumn\u00edci s pomocou ponorky objavili na dne oce\u00e1nu pri Galap\u00e1goch doteraz nezn\u00e1mu chobotnicu, modr\u00fa ako oce\u00e1n…\n","protected":false},"author":2,"featured_media":79433,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[8],"tags":[29362,29363,33,17704,43,40,42,36,50,49,48],"class_list":["post-79432","post","type-post","status-publish","format-standard","has-post-thumbnail","category-svet","tag-chobotnica","tag-galapag","tag-news","tag-ocean","tag-sk","tag-slovak","tag-slovencina","tag-spravy","tag-svet","tag-world","tag-world-news"],"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@sk\/116634916201053832","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/posts\/79432","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/comments?post=79432"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/posts\/79432\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/media\/79433"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/media?parent=79432"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/categories?post=79432"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/tags?post=79432"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
