Drobn\u00e1 ostranka s rozev\u0159en\u00fdmi dlan\u011bmi<\/strong><\/p>\n

Homalocantha zamboi je mal\u00e1, ale nesm\u00edrn\u011b p\u016fsobiv\u00e1 ostranka, kterou popsali ameri\u010dt\u00ed malakologov\u00e9 man\u017eel\u00e9 Burchovi v roce 1960. Rodov\u00e9 jm\u00e9no Homalocantha vych\u00e1z\u00ed z \u0159e\u010dtiny a znamen\u00e1 zhruba \u201eploch\u00fd trn\u201c, co\u017e p\u0159esn\u011b vystihuje hlavn\u00ed ozdobu t\u011bchto lastur. Jejich ostny toti\u017e nejsou \u0161pi\u010dat\u00e9 jako u v\u011bt\u0161iny p\u0159\u00edbuzn\u00fdch, ale na konc\u00edch se roz\u0161i\u0159uj\u00ed do ploch\u00fdch lopatek, kter\u00e9 vypadaj\u00ed jako drobn\u00e9 rozev\u0159en\u00e9 dlan\u011b nebo listy.<\/p>\n

Druh pat\u0159\u00ed do \u010deledi Muricidae, tedy mezi ostranky, skupinu drav\u00fdch mo\u0159sk\u00fdch pl\u017e\u016f zn\u00e1mou nesm\u00edrnou rozmanitost\u00ed trn\u016f, lamel a v\u00fdr\u016fstk\u016f.

Jak vypad\u00e1<\/h3>\n

Schr\u00e1nka je pom\u011brn\u011b mal\u00e1, obvykle kolem \u010dty\u0159 a\u017e \u0161esti centimetr\u016f, s n\u00edzkou v\u011b\u017e\u00ed a kr\u00e1tk\u00fdm sifon\u00e1ln\u00edm kan\u00e1lkem. Na z\u00e1vitech vystupuj\u00ed pod\u00e9ln\u00e9 varixy a z nich vyb\u00edhaj\u00ed dlouh\u00e9 ostny, jejich\u017e konce se roz\u0161i\u0159uj\u00ed do ploch\u00fdch, na okraji jemn\u011b rozt\u0159epen\u00fdch lopatek. Nejdel\u0161\u00ed ostny b\u00fdvaj\u00ed na posledn\u00edm z\u00e1vitu kolem \u00fast\u00ed, kde tvo\u0159\u00ed n\u00e1padn\u00fd v\u011bnec.<\/p>\n

Zbarven\u00ed je v\u011bt\u0161inou jemn\u00e9, b\u00edl\u00e9, kr\u00e9mov\u00e9 nebo lehce nar\u016f\u017eov\u011bl\u00e9, n\u011bkdy s na\u017eloutl\u00fdmi \u010di hn\u011bdav\u00fdmi t\u00f3ny. Povrch mezi ostny je pokryt drobn\u00fdm spir\u00e1ln\u00edm \u017eebrov\u00e1n\u00edm a \u0161upinkami. \u00dast\u00ed je mal\u00e9, ov\u00e1ln\u00e9 a uvnit\u0159 b\u00edl\u00e9 nebo r\u016f\u017eov\u00e9. Celkov\u00fd dojem je k\u0159ehk\u00fd a t\u00e9m\u011b\u0159 krajkov\u00fd.<\/p>\n

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

Homalocantha zamboi se li\u0161\u00ed od v\u011bt\u0161iny ostranek pr\u00e1v\u011b lopatkovit\u00fdmi konci ostn\u016f, kter\u00e9 jinde nenajdete v takov\u00e9 podob\u011b. Rod Homalocantha zahrnuje n\u011bkolik podobn\u00fdch druh\u016f, nap\u0159\u00edklad Homalocantha scorpio, jej\u00ed\u017e ostny b\u00fdvaj\u00ed del\u0161\u00ed, tmav\u0161\u00ed a p\u0159ipom\u00ednaj\u00ed sp\u00ed\u0161e pa\u0159\u00e1ty. Homalocantha zamboi p\u016fsob\u00ed sv\u011btleji a jemn\u011bji, se \u0161ir\u0161\u00edmi a ploch\u0161\u00edmi lopatkami. Ur\u010den\u00ed mezi druhy rodu \u010dasto vy\u017eaduje zku\u0161en\u00e9 oko a srovn\u00e1n\u00ed s dob\u0159e dolo\u017een\u00fdmi kusy.<\/p>\n

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

Tato ostranka je spojov\u00e1na hlavn\u011b s vodami Filip\u00edn a okoln\u00ed oblasti z\u00e1padn\u00edho Pacifiku, kde \u017eije na \u00fatesech a na tvrd\u00e9m dn\u011b mezi kameny a kor\u00e1ly. Jako ostatn\u00ed ostranky je drav\u00e1 a \u017eiv\u00ed se hlavn\u011b jin\u00fdmi m\u011bkk\u00fd\u0161i, jejich\u017e schr\u00e1nky dok\u00e1\u017ee provrtat nebo otev\u0159\u00edt. Roz\u0161\u00ed\u0159en\u00e9 ostny j\u00ed pravd\u011bpodobn\u011b pom\u00e1haj\u00ed udr\u017eet se mezi kameny a z\u00e1rove\u0148 ji chr\u00e1n\u00ed p\u0159ed pred\u00e1tory.<\/p>\n

Ostny ostranek vznikaj\u00ed postupn\u011b. Pl\u017e roste po etap\u00e1ch a na konci ka\u017ed\u00e9 z nich vytvo\u0159\u00ed nov\u00fd varix i s \u0159adou ostn\u016f. Ka\u017ed\u00e1 lastura je tak z\u00e1znamem sv\u00e9ho vlastn\u00edho r\u016fstu. U rodu Homalocantha je tento proces obzvl\u00e1\u0161\u0165 fascinuj\u00edc\u00ed, proto\u017ee okraj pl\u00e1\u0161t\u011b mus\u00ed vytvarovat nejen dlouh\u00fd ost\u011bn, ale i jeho roz\u0161\u00ed\u0159enou lopatku na konci.<\/p>\n

Lopatky jsou nejk\u0159eh\u010d\u00ed \u010d\u00e1st\u00ed lastury a v p\u0159\u00edrod\u011b se snadno po\u0161kod\u00ed o kameny nebo p\u0159i napaden\u00ed. Kusy s dob\u0159e zachovan\u00fdmi, soum\u011brn\u00fdmi lopatkami proto sb\u011bratel\u00e9 zvl\u00e1\u0161\u0165 oce\u0148uj\u00ed. Drobn\u00e9 odchylky a nepravidelnosti jsou p\u0159itom b\u011b\u017en\u00e9 a vypov\u00eddaj\u00ed o tom, jak n\u00e1ro\u010dn\u00e9 prost\u0159ed\u00ed pl\u017e ob\u00fdval.<\/p>\n

Ostranky obecn\u011b pat\u0159\u00ed k lastur\u00e1m, kter\u00e9 p\u0159itahovaly pozornost p\u0159\u00edrodov\u011bdc\u016f i um\u011blc\u016f. Jejich trojrozm\u011brn\u00e9 tvary se objevuj\u00ed na rytin\u00e1ch, ve \u0161perka\u0159stv\u00ed i v modern\u00edm designu. Homalocantha zamboi je mal\u00fdm, ale v\u00fdmluvn\u00fdm d\u016fkazem, jak vynal\u00e9zav\u00e1 dok\u00e1\u017ee p\u0159\u00edroda b\u00fdt.<\/p>\n

Vyplat\u00ed se prohl\u00e9dnout si lasturu z v\u00edce stran. Shora vynikne pravideln\u00e9 rozlo\u017een\u00ed varix\u016f, z boku zase d\u00e9lka a zak\u0159iven\u00ed ostn\u016f a zep\u0159edu jemn\u00e1 stavba \u00fast\u00ed. Ka\u017ed\u00fd \u00fahel pohledu uk\u00e1\u017ee jin\u00fd detail, a proto se drobn\u00e9 ostranky tak dob\u0159e hod\u00ed k fotografov\u00e1n\u00ed i k pozorov\u00e1n\u00ed lupou.<\/p>\n

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

Tato lastura si zaslou\u017e\u00ed m\u00edsto, kde vynikne jej\u00ed prostorov\u00e1 stavba: ve vitr\u00edn\u011b, pod sklen\u011bn\u00fdm poklopem nebo na stoj\u00e1nku. D\u00edky mal\u00e9 velikosti se hod\u00ed i do sb\u00edrky drobn\u00fdch lastur a do kabinetu zam\u011b\u0159en\u00e9ho na \u010dele\u010f Muricidae. V interi\u00e9ru p\u016fsob\u00ed jako miniaturn\u00ed p\u0159\u00edrodn\u00ed socha. Jako d\u00e1rek pot\u011b\u0161\u00ed zku\u0161en\u00e9 sb\u011bratele, kte\u0159\u00ed ocen\u00ed jej\u00ed neobvykl\u00fd tvar.<\/p>\n

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

S lasturou zach\u00e1zejte velmi opatrn\u011b a berte ji za t\u011blo schr\u00e1nky, nikdy za ostny. Chra\u0148te ji p\u0159ed p\u00e1dem a n\u00e1razy a neumis\u0165ujte ji na p\u0159\u00edm\u00e9 slunce, kter\u00e9 m\u016f\u017ee jemn\u00e9 barvy vybledit. Prach mezi ostny odstran\u00edte m\u011bkk\u00fdm \u0161t\u011btcem nebo jemn\u00fdm proudem vzduchu. Nepou\u017e\u00edvejte chemick\u00e9 \u010disti\u010de ani ocet. Pro jemn\u00fd lesk sta\u010d\u00ed kapka oleje rozet\u0159en\u00e1 do sucha.<\/p>\n
