Chicoreus brunneus \u2013 ostranka hn\u011bd\u00e1<\/h2>\n

Krajka z tmav\u00e9 \u010dokol\u00e1dy<\/strong><\/p>\n

Chicoreus brunneus pat\u0159\u00ed do \u010deledi Muricidae, tedy mezi ostranky, kter\u00e9 jsou mezi sb\u011brateli proslul\u00e9 bohat\u011b zdoben\u00fdmi schr\u00e1nkami s trny, lamelami a krajkovit\u00fdmi v\u00fdb\u011b\u017eky. Druh popsal n\u011bmeck\u00fd p\u0159\u00edrodov\u011bdec Heinrich Friedrich Link v roce 1807. Druhov\u00e9 jm\u00e9no \u201ebrunneus\u201c znamen\u00e1 v latin\u011b hn\u011bd\u00fd a p\u0159esn\u011b vystihuje hlavn\u00ed dojem, kter\u00fd ulita vyvol\u00e1v\u00e1: sytou, tmavou barvu p\u0159ipom\u00ednaj\u00edc\u00ed ho\u0159kou \u010dokol\u00e1du nebo pra\u017een\u00e9 kakao.<\/p>\n

Rod Chicoreus dostal jm\u00e9no podle \u010dekanky, latinsky cichorium, proto\u017ee \u010dlenit\u00e9 v\u00fdb\u011b\u017eky na varixech n\u011bkter\u00fdch druh\u016f p\u0159ipom\u00ednaj\u00ed kade\u0159av\u00e9 listy t\u00e9to rostliny. U ostranky hn\u011bd\u00e9 jsou tyto v\u00fdb\u011b\u017eky krat\u0161\u00ed a hust\u0161\u00ed ne\u017e u n\u011bkter\u00fdch jej\u00edch p\u0159\u00edbuzn\u00fdch, ale d\u00edky tmav\u00e9 barv\u011b p\u016fsob\u00ed velmi dramaticky. Ulita vypad\u00e1, jako by ji n\u011bkdo vy\u0159ezal z tmav\u00e9ho d\u0159eva a ozdobil drobnou \u0159ezbou. P\u0159itom jde o d\u00edlo, kter\u00e9 pl\u017e budoval postupn\u011b, z\u00e1vit po z\u00e1vitu, b\u011bhem n\u011bkolika let sv\u00e9ho \u017eivota na \u00fatesu. Ka\u017ed\u00fd varix tak p\u0159edstavuje jednu kapitolu jeho r\u016fstu a p\u0159i pozorn\u00e9m pohledu lze tyto kapitoly na ulit\u011b spo\u010d\u00edtat.<\/p>\n

Jak vypad\u00e1<\/h3>\n

Schr\u00e1nka je pevn\u00e1, v\u0159etenovit\u00e1, s kr\u00e1tkou a\u017e st\u0159edn\u011b dlouhou \u0161pi\u010dkou a pom\u011brn\u011b kr\u00e1tk\u00fdm sifon\u00e1ln\u00edm kan\u00e1lkem. Obvykl\u00e1 velikost dosp\u011bl\u00fdch jedinc\u016f se pohybuje zhruba mezi p\u011bti a deseti centimetry. Ka\u017ed\u00fd z\u00e1vit nese t\u0159i v\u00fdrazn\u00e9 varixy, tedy vyv\u00fd\u0161en\u00e9 h\u0159ebeny, kter\u00e9 vznikaj\u00ed v obdob\u00edch, kdy pl\u017e na \u010das p\u0159estane r\u016fst. Varixy jsou zdoben\u00e9 \u0159adami kr\u00e1tk\u00fdch, zkade\u0159en\u00fdch v\u00fdb\u011b\u017ek\u016f, jejich\u017e konce se m\u00edrn\u011b st\u00e1\u010dej\u00ed. Povrch je tmav\u011b hn\u011bd\u00fd a\u017e t\u00e9m\u011b\u0159 \u010dern\u00fd, mezi varixy s jemn\u00fdm spir\u00e1ln\u00edm \u017eebrov\u00e1n\u00edm. \u00dast\u00ed je ov\u00e1ln\u00e9 a b\u00edl\u00e9 nebo kr\u00e9mov\u00e9, okraj \u00fast\u00ed a v\u0159et\u00e1nko b\u00fdvaj\u00ed \u010dasto zbarveny do r\u016f\u017eov\u00fdch, oran\u017eov\u00fdch \u010di lososov\u00fdch t\u00f3n\u016f, co\u017e vytv\u00e1\u0159\u00ed kr\u00e1sn\u00fd kontrast s tmavou schr\u00e1nkou.<\/p>\n

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

Od p\u0159\u00edbuzn\u00e9ho druhu Chicoreus ramosus, nejv\u011bt\u0161\u00ed ostranky rodu, odli\u0161uje ostranku hn\u011bdou mnohem men\u0161\u00ed velikost a tmav\u00e9 zbarven\u00ed; Chicoreus ramosus b\u00fdv\u00e1 sv\u011btl\u00fd, b\u011blav\u00fd s hn\u011bd\u00fdmi p\u00e1sky a m\u00e1 dlouh\u00e9, rozv\u011btven\u00e9 v\u00fdb\u011b\u017eky. Chicoreus capucinus je rovn\u011b\u017e tmav\u00fd, ale jeho varixy jsou n\u00edzk\u00e9 a t\u00e9m\u011b\u0159 bez v\u00fdb\u011b\u017ek\u016f. Pro ostranku hn\u011bdou jsou tedy typick\u00e9 t\u0159i varixy s hust\u00fdmi kr\u00e1tk\u00fdmi \u201ekrajkami\u201c, t\u00e9m\u011b\u0159 jednolit\u00e1 tmav\u00e1 barva a sv\u011btl\u00e9, \u010dasto r\u016f\u017eov\u011b lemovan\u00e9 \u00fast\u00ed.<\/p>\n

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

Chicoreus brunneus je roz\u0161\u00ed\u0159en v tropick\u00e9m Indopacifiku od v\u00fdchodn\u00ed Afriky p\u0159es Indon\u00e9sii a Filip\u00edny a\u017e po ostrovy z\u00e1padn\u00edho Pacifiku a severn\u00ed Austr\u00e1lii. \u017dije v m\u011bl\u010din\u00e1ch na kor\u00e1lov\u00fdch \u00fatesech, mezi kameny a \u00falomky kor\u00e1l\u016f, \u010dasto v p\u0159\u00edlivov\u00e9 z\u00f3n\u011b. Stejn\u011b jako ostatn\u00ed ostranky je to dravec. \u017div\u00ed se hlavn\u011b ml\u017ei a jin\u00fdmi pl\u017ei; u ostranek je zn\u00e1mo, \u017ee dok\u00e1\u017eou pomoc\u00ed jaz\u00fd\u010dku a sekretu vyvrtat do schr\u00e1nky ko\u0159isti otvor nebo ko\u0159ist otev\u0159\u00edt tlakem na okraj ulity. Tmav\u00e1 barva mu pom\u00e1h\u00e1 splynout se st\u00edny a porostem \u0159as mezi kameny. Ostranky maj\u00ed i bohatou kulturn\u00ed historii: p\u0159\u00edbuzn\u00e9 druhy ze St\u0159edomo\u0159\u00ed byly ve starov\u011bku zdrojem vz\u00e1cn\u00e9ho purpurov\u00e9ho barviva, kter\u00e9 si mohli dovolit jen nejbohat\u0161\u00ed.<\/p>\n

Kam se hod\u00ed<\/h3>\n

Ostranka hn\u011bd\u00e1 je vd\u011b\u010dn\u00fdm kusem pro sb\u00edrku ostranek i pro ka\u017ed\u00e9ho, kdo hled\u00e1 lasturu s v\u00fdraznou strukturou. Ve vitr\u00edn\u011b kr\u00e1sn\u011b dopln\u00ed sv\u011btl\u00e9 druhy, nap\u0159\u00edklad Chicoreus ramosus nebo Hexaplex cichoreum, a vynikne na sv\u011btl\u00e9m podkladu, kde se naplno projev\u00ed krajkovit\u00e1 stavba varix\u016f. Uplatn\u00ed se jako dekorace na knihovn\u011b, psac\u00edm stole nebo v koupeln\u011b a d\u00edky tmav\u00e9 barv\u011b p\u016fsob\u00ed elegantn\u011b i v modern\u00edch interi\u00e9rech.

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

V\u00fdb\u011b\u017eky na varixech jsou pevn\u00e9, ale jejich jemn\u00e9 okraje se mohou p\u0159i p\u00e1du od\u0161t\u00edpnout, proto ulitu ukl\u00e1dejte na stabiln\u00ed m\u00edsto a chra\u0148te ji p\u0159ed n\u00e1razy. Neumis\u0165ujte ji dlouhodob\u011b na p\u0159\u00edm\u00e9 slunce, kter\u00e9 by mohlo vybledit r\u016f\u017eov\u00e9 t\u00f3ny v \u00fast\u00ed. Prach z \u010dlenit\u00e9ho povrchu odstran\u00edte m\u011bkk\u00fdm \u0161t\u011btcem nebo kart\u00e1\u010dkem, hladk\u00e9 \u010d\u00e1sti sta\u010d\u00ed ot\u0159\u00edt m\u011bkk\u00fdm such\u00fdm had\u0159\u00edkem. Nepou\u017e\u00edvejte chemick\u00e9 \u010disti\u010de, ocet ani jin\u00e9 kyseliny. Pro hlub\u0161\u00ed barvu a jemn\u00fd lesk naneste na had\u0159\u00edk kapku oleje, rozet\u0159ete ji a p\u0159ebytek vyle\u0161t\u011bte do sucha.<\/p>\n
