Antarktida, zmrzl\u00fd kontinent na konci sv\u011bta, byla dlouho bez krab\u016f. Ledov\u00e9 vody a mraziv\u00e9 teploty dr\u017eely tyto pred\u00e1tory drt\u00edc\u00ed schr\u00e1nky stranou.

V\u011bdci ned\u00e1vno objevili kraby kr\u00e1lovsk\u00e9 v bl\u00edzkosti antarktick\u00e9ho svahu a se zah\u0159\u00edvaj\u00edc\u00edmi se vodami neexistuje nic, co by jim br\u00e1nilo ve st\u011bhov\u00e1n\u00ed.<\/p>\n\n
Krabi kr\u00e1lov\u0161t\u00ed jsou \u017erav\u00ed pred\u00e1to\u0159i, kte\u0159\u00ed pou\u017e\u00edvaj\u00ed sv\u00e1 siln\u00e1 klepeta k rozdrcen\u00ed schr\u00e1nek m\u011bkk\u00fd\u0161\u016f, hv\u011bzdic a dal\u0161\u00edch mo\u0159sk\u00fdch organism\u016f s m\u011bkk\u00fdm t\u011blem.

Krabi kr\u00e1lov\u0161t\u00ed nejsou jedinou hrozbou pro zmrzl\u00fd kontinent.

Vzhledem k \u010detn\u00fdm hrozb\u00e1m, kter\u00fdm Antarktida \u010del\u00ed, je nezbytn\u00e9 u\u010dinit kroky k ochran\u011b tohoto jedine\u010dn\u00e9ho a k\u0159ehk\u00e9ho ekosyst\u00e9mu.

Invaze krab\u016f kr\u00e1lovsk\u00fdch do Antarktidy je v\u00fdstrahou pro sv\u011bt.
