Tento mlad\u00fd mro\u017e, jeho\u017e velikost byla p\u0159ibli\u017en\u011b jako u kr\u00e1vy, se rychle stal m\u00edstn\u00ed celebritou.

    Experti se domn\u00edvaj\u00ed, \u017ee tento mro\u017e pravd\u011bpodobn\u011b poch\u00e1z\u00ed bu\u010f z Gr\u00f3nska, nebo z norsk\u00e9ho souostrov\u00ed \u0160picberky.

P\u0159edpokl\u00e1d\u00e1 se, \u017ee je to stejn\u00fd mro\u017e, kter\u00fd byl spat\u0159en v D\u00e1nsku v polovin\u011b \u00fanora.<\/p>\n\n

Biologov\u00e9 nedok\u00e1zali ur\u010dit jeho pohlav\u00ed pouze na z\u00e1klad\u011b jeho kl\u016f. P\u0159esto\u017ee se nach\u00e1zel daleko od domova, mro\u017e se zd\u00e1l b\u00fdt v pom\u011brn\u011b dobr\u00e9m zdravotn\u00edm stavu. Pracovn\u00edk RSPCA zodpov\u011bdn\u00fd za z\u00e1chranu zv\u00ed\u0159at, Ellie West, uvedl, \u017ee mro\u017e odpo\u010d\u00edval a byl m\u00edrn\u011b podvy\u017eiven\u00fd, ale nevykazoval \u017e\u00e1dn\u00e9 zn\u00e1mky nemoci nebo zran\u011bn\u00ed.<\/p>\n\n

Mro\u017e ve Walesu odpo\u010d\u00edval p\u0159ibli\u017en\u011b dva dny a pot\u00e9 se 22. b\u0159ezna vr\u00e1til zp\u011bt do mo\u0159e.

    Obavy ohledn\u011b ochrany p\u0159\u00edrody<\/h2>\n\n

    RSPCA a Welsh Marine Life Rescue pe\u010dliv\u011b sledovali mro\u017ee po dobu jeho pobytu v Pembrokeshire, aby zajistili jeho pohodu a zabr\u00e1nili ru\u0161en\u00ed. Lucy Babey, kter\u00e1 vede odd\u011blen\u00ed v\u011bdy a ochrany p\u0159\u00edrody organizace ORCA, zd\u016fraznila v\u00fdznam udr\u017eov\u00e1n\u00ed bezpe\u010dn\u00e9ho odstupu od mro\u017ee. \u201eToto zv\u00ed\u0159e bude z ve\u0161ker\u00e9ho plav\u00e1n\u00ed docela vy\u010derpan\u00e9,\u201c uvedla. \u201ePravd\u011bpodobn\u011b bude ve stresu, proto\u017ee se nenach\u00e1z\u00ed v prost\u0159ed\u00ed, na kter\u00e9 je zvykl\u00e9.\u201c<\/p>\n\n

    P\u0159esto\u017ee se jednalo o prvn\u00ed p\u0159\u00edpad, kdy byl mro\u017e spat\u0159en na pob\u0159e\u017e\u00ed Pembrokeshire, nen\u00ed to poprv\u00e9, co nav\u0161t\u00edvili mro\u017ei Irsko a Wales. Od roku 1979 bylo potvrzeno osm pozorov\u00e1n\u00ed mro\u017e\u016f v Irsku a n\u011bkolik ve Skotsku. V roce 2018 byl spat\u0159en mro\u017e, jak cestuje na n\u011bkolik ostrov\u016f ve Skotsku po dobu n\u011bkolika m\u011bs\u00edc\u016f.<\/p>\n\n
