Ostranka s rohy zahnut\u00fdmi vzh\u016fru<\/strong><\/p>\n

Chicoreus axicornis je st\u0159edn\u011b velk\u00e1 ostranka z \u010deledi Muricidae, kter\u00e1 zaujme p\u0159edev\u0161\u00edm dlouh\u00fdmi, elegantn\u011b zak\u0159iven\u00fdmi ostny. Druh popsal na po\u010d\u00e1tku devaten\u00e1ct\u00e9ho stolet\u00ed francouzsk\u00fd p\u0159\u00edrodov\u011bdec Jean-Baptiste Lamarck, jeden z velk\u00fdch pr\u016fkopn\u00edk\u016f studia bezobratl\u00fdch \u017eivo\u010dich\u016f. Druhov\u00e9 jm\u00e9no axicornis je slo\u017eeno z latinsk\u00fdch slov a odkazuje na rohovit\u00e9 v\u00fdr\u016fstky, kter\u00e9 vyb\u00edhaj\u00ed z varix\u016f a st\u00e1\u010dej\u00ed se vzh\u016fru jako parohy nebo rohy.<\/p>\n

Jak vypad\u00e1<\/h3>\n

Schr\u00e1nka je v\u0159etenovit\u00e1, se st\u0159edn\u011b vysok\u00fdm, \u0161pi\u010dat\u00fdm z\u00e1vitem a prot\u00e1hl\u00fdm sifon\u00e1ln\u00edm kan\u00e1lkem na p\u0159edn\u00edm konci.

Z nich vyr\u016fstaj\u00ed dlouh\u00e9, \u0161t\u00edhl\u00e9 a na konc\u00edch m\u00edrn\u011b rozt\u0159epen\u00e9 ostny. Nejdel\u0161\u00ed z nich jsou ty na rameni posledn\u00edho z\u00e1vitu, kter\u00e9 se v\u00fdrazn\u011b st\u00e1\u010dej\u00ed dozadu a vzh\u016fru, sm\u011brem k vrcholu schr\u00e1nky.<\/p>\n

Mezi varixy jsou patrn\u00e9 drobn\u00e9 uzl\u00edky a jemn\u00e1 spir\u00e1ln\u00ed \u017eebra, kter\u00e1 dod\u00e1vaj\u00ed povrchu plastickou strukturu.<\/p>\n

Pozn\u00e1vac\u00ed znaky<\/h3>\n

Ostranku rohatou nejsn\u00e1ze pozn\u00e1te podle dlouh\u00fdch, vzh\u016fru zahnut\u00fdch ostn\u016f na rameni, kter\u00e9 jsou v\u00fdrazn\u011b del\u0161\u00ed ne\u017e ostatn\u00ed ostny. Od ostranky v\u011btvit\u00e9 Chicoreus ramosus se li\u0161\u00ed men\u0161\u00ed velikost\u00ed, \u0161t\u00edhlej\u0161\u00edm tvarem a m\u00e9n\u011b listovit\u011b rozt\u0159epen\u00fdmi ostny. Podobn\u00fd druh Chicoreus cornucervi, zn\u00e1m\u00fd z Austr\u00e1lie, m\u00e1 ostny je\u0161t\u011b del\u0161\u00ed a v\u00fdrazn\u011b rozv\u011btven\u00e9 jako jelen\u00ed paro\u017e\u00ed a jeho schr\u00e1nka b\u00fdv\u00e1 tmav\u0161\u00ed. Ostranka rohat\u00e1 stoj\u00ed mezi ob\u011bma: je elegantn\u00ed a jemn\u00e1, p\u0159itom ne tak extravagantn\u00ed.<\/p>\n

\u010c\u00edm je v\u00fdjime\u010dn\u00e1<\/h3>\n

Stejn\u011b jako ostatn\u00ed ostranky je i Chicoreus axicornis dravec. \u017div\u00ed se zejm\u00e9na ml\u017ei a jin\u00fdmi pl\u017ei. Ostranky dok\u00e1\u017eou do schr\u00e1nky ko\u0159isti vyvrtat drobn\u00fd otvor pomoc\u00ed sv\u00e9ho jaz\u00fd\u010dku, radule, a sekretu, kter\u00fd zm\u011bk\u010duje v\u00e1penat\u00fd materi\u00e1l. Otvorem pak vsunou chobotek a m\u011bkk\u00e9 t\u011blo ko\u0159isti poz\u0159ou. Druh \u017eije v tepl\u00fdch vod\u00e1ch z\u00e1padn\u00edho Pacifiku, zejm\u00e9na v oblasti Filip\u00edn, kde ob\u00fdv\u00e1 skalnat\u00e9 a p\u00eds\u010dit\u00e9 dno od m\u011bl\u010din a\u017e po hlub\u0161\u00ed pob\u0159e\u017en\u00ed vody.<\/p>\n

Ostny ostranek nejsou jen ozdobou. Pom\u00e1haj\u00ed chr\u00e1nit pl\u017ee p\u0159ed pred\u00e1tory, nap\u0159\u00edklad rybami a kraby, kte\u0159\u00ed by se jinak mohli pokusit schr\u00e1nku rozlomit. Z\u00e1rove\u0148 zpev\u0148uj\u00ed okraj \u00fast\u00ed a pom\u00e1haj\u00ed pl\u017ei dr\u017eet se ve \u0161t\u011brbin\u00e1ch a na nerovn\u00e9m dn\u011b. Tvar a d\u00e9lka ostn\u016f se u jednotliv\u00fdch kus\u016f li\u0161\u00ed podle toho, v jak\u00e9m prost\u0159ed\u00ed pl\u017e vyr\u016fstal a jak klidn\u00e9 bylo okoln\u00ed mo\u0159e.<\/p>\n

Ostranky maj\u00ed i zaj\u00edmavou kulturn\u00ed historii. Jejich st\u0159edomo\u0159\u0161t\u00ed p\u0159\u00edbuzn\u00ed byli ve starov\u011bku zdrojem proslul\u00e9ho tyrsk\u00e9ho purpuru, barviva tak drah\u00e9ho, \u017ee bylo vyhrazeno pro od\u011bvy panovn\u00edk\u016f a vysok\u00fdch hodnost\u00e1\u0159\u016f. Barvivo se z\u00edsk\u00e1valo ze \u017el\u00e1zy pl\u017e\u016f a jeho v\u00fdroba vy\u017eadovala obrovsk\u00e9 mno\u017estv\u00ed \u017eivo\u010dich\u016f.<\/p>\n

P\u00e9\u010de a manipulace<\/h3>\n

Ostny jsou k\u0159ehk\u00e9, proto lasturu berte do ruky opatrn\u011b za t\u011blo schr\u00e1nky, ne za v\u00fdr\u016fstky. Chra\u0148te ji p\u0159ed p\u00e1dem a dlouhodob\u00fdm p\u0159\u00edm\u00fdm sluncem. Prach mezi ostny odstran\u00edte m\u011bkk\u00fdm \u0161t\u011btcem. Nepou\u017e\u00edvejte chemick\u00e9 \u010disti\u010de ani ocet. Pro jemn\u00fd lesk m\u016f\u017eete rozet\u0159\u00edt kapku oleje do sucha.<\/p>\n
