Len po\u010das tohto roka ich umrelo 769 !<\/p>\n

Ide o najhor\u0161\u00ed rok v dejin\u00e1ch. Doteraz dr\u017eal „rekord“ rok 2010, kedy kv\u00f4li chladnej vode zomrelo na stres 766 t\u00fdchto n\u00e1dhern\u00fdch zvierat.
\n„Nikdy by sme neverili, \u017ee to \u010d\u00edslo bude prekonan\u00e9 – a rozhodne nie tak skoro,“ uviedol Patrick Rose, \u0161\u00e9f organiz\u00e1cie, ktor\u00e1 sa sna\u017e\u00ed mro\u017eov zachr\u00e1ni\u0165.<\/p>\n

„Kv\u00f4li posledn\u00fdm dvom rokom a r\u00fdchlosti, ako vymieranie nabralo sp\u00e1d, u\u017e netu\u0161\u00edme, \u010di je v\u00f4bec ich popul\u00e1cia schopn\u00e1 \u010falej pre\u017e\u00edva\u0165,“ dodal. V roku 2010 e\u0161te \u017eilo u Floridy 5077 lamant\u00ednov a teraz je ich skoro o tretinu menej. Najviac tak\u00fdchto mierumilovn\u00fdch tvorov zomrelo kv\u00f4li „krvav\u00e9mu pr\u00edlivu“ – \u010di\u017ee premno\u017eeniu ist\u00e9ho typu toxick\u00fdch rias. Ale najmenej stovka zahynula z nezn\u00e1meho d\u00f4vodu; pod\u013ea v\u0161etk\u00e9ho na doposia\u013e nezn\u00e1my druh bakt\u00e9rie alebo v\u00edrusu.<\/p>\n

\u010co je to lamant\u00edn ?<\/p>\n

Lamant\u00edn \u00a0je jedin\u00fd rod z \u010de\u013eade lamant\u00ednovit\u00fdch. S\u00fa to ve\u013ek\u00e9 vodn\u00e9 cicavce zn\u00e1me tie\u017e ako morsk\u00e9 kravy. Lamant\u00ednovit\u00e9 sa l\u00ed\u0161ia od dugongovit\u00fdch v tvare lebky a chvosta. Chvost lamant\u00edna m\u00e1 p\u00e1dlovit\u00fd tvar, zatia\u013e \u010do chvost dugonga m\u00e1 tvar vidlicovit\u00fd.

Existuj\u00fa tri druhy lamant\u00ednov: Lamant\u00edn \u00a0senegalsk\u00fd – ob\u00fdva z\u00e1padn\u00e9 pobre\u017eie Afriky, Lamant\u00edn juhoamerick\u00fd – v\u00fdchodn\u00e9 pobre\u017eie Ju\u017enej Ameriky a\u00a0Lamant\u00edn \u0161irokonos\u00fd \u010di\u017ee lamantin \u017eije v plytk\u00fdch, bahnit\u00fdch pobre\u017en\u00fdch oblastiach Severnej, Strednej a Ju\u017enej Ameriky a Karibsk\u00e9ho mora. Na ostrove Portoriko sa v domorodom jazyku lamant\u00ednom hovorilo „Manat\u00ed“. Toto meno sa odrazilo aj v latinskom n\u00e1zve (Trichechus manatus) a pre\u0161lo aj do niektor\u00fdch \u010fal\u0161\u00edch jazykov, napr\u00edklad do angli\u010dtiny.<\/p>\n

Lamant\u00edn floridsk\u00fd bol po nejak\u00fa dobu pova\u017eovan\u00fd za samostatn\u00fd druh, ale ITIS (Integrovan\u00fd taxonomick\u00fd informa\u010dn\u00fd syst\u00e9m) ho preklasifikoval ako poddruh Lamant\u00edna \u0161irokonos\u00e9ho. Dosahuje d\u013a\u017eku \u00a0viac ako 4,5 m a \u017eije ako v sladkej, tak i \u00a0v slanej vode. Predt\u00fdm bol loven\u00fd pre olej a m\u00e4so, ale teraz je chr\u00e1nen\u00fd z\u00e1konom.<\/p>\n

Lamant\u00edni spolu s lenochodmi s\u00fa medzi cicavcami jedin\u00fdmi v\u00fdnimkami u ktor\u00fdch nie je kr\u010dn\u00e1 chrbtica tvoren\u00e1 7 stavcami. (Wikipedia)<\/p>\n
