Nors primena ry\u0161kius \u017eiedus, \u0161ie bestuburiai grob\u012f sugriebia \u010diuptuvais ir geliamosiomis l\u0105stel\u0117mis.<\/p>\n
Odesos srities pietuose, nacionalinio parko Tuzlos limanai s\u016briuose vandens telkiniuose, tyr\u0117jai u\u017efiksavo j\u016brines anemonas, dar vadinamas aktinijomis. Apie steb\u0117jim\u0105 prane\u0161\u0117 parko mokslini\u0173 tyrim\u0173 padalinio vadovas, biologijos moksl\u0173 daktaras Ivanas Rusevas, pasidalij\u0119s vaizdo \u012fra\u0161u.<\/p>\n
J\u016brin\u0117s anemonos da\u017enai vadinamos povandenin\u0117mis g\u0117l\u0117mis d\u0117l ry\u0161ki\u0173 spalv\u0173 ir \u010diuptuv\u0173, primenan\u010di\u0173 \u017eiedlapius. Vis d\u0117lto tai ne augalai, o pl\u0117\u0161r\u016bs knidarijai, artimi koraliniams polipams.<\/p>\n
\u201eJos laukia grobio i\u0161skleidusios \u010diuptuvus. Kai smulkus v\u0117\u017eiagyvis, kirm\u0117l\u0117 ar \u017euv\u0173 mailius palie\u010dia \u010diuptuv\u0105, gelian\u010dios l\u0105stel\u0117s suveikia ir paraly\u017eiuoja auk\u0105\u201c, \u2013 sak\u0117 Ivanas Rusevas.<\/p>\n
Skirtingai nei daugelis koral\u0173, anemonos neturi kieto mineralinio skeleto. J\u0173 k\u016bnas mink\u0161tas, mai\u0161elio formos, o apa\u010dioje yra raumeninga p\u0117da, kuria jos prisitvirtina prie akmen\u0173, kriaukli\u0173, medini\u0173 poli\u0173 ar kito kieto pagrindo.<\/p>\n
Vir\u0161utin\u0117je k\u016bno dalyje yra burnos anga, apsupta daugyb\u0117s plon\u0173 \u010diuptuv\u0173 \u017eied\u0173. Kai kuri\u0173 r\u016b\u0161i\u0173 j\u0173 gali b\u016bti apie 200, o \u010diuptuvai padengti gelian\u010diosiomis l\u0105stel\u0117mis, kurios padeda ir gintis, ir med\u017eioti.<\/p>\n
Tuzlos liman\u0173 ekosistemoje s\u0105lygos gali greitai kisti: svyruoja s\u016brumas, temperat\u016bra ir deguonies kiekis. Tod\u0117l, pasak mokslinink\u0173, vietoje tolim\u0173 migracij\u0173 anemonos nepalankiu laikotarpiu da\u017eniau pasitraukia \u012f gilesnes vietas tame pa\u010diame telkinyje ir sul\u0117tina aktyvum\u0105.<\/p>\n
Specialistai pabr\u0117\u017eia, kad j\u016brin\u0117s anemonos gali daugintis tiek lytiniu b\u016bdu, \u012f vanden\u012f i\u0161skirdamos lytines l\u0105steles, tiek nelytiniu, dalydamosi ar pumpuruodamos. Pasaulyje apra\u0161yta daugiau nei 1 000 r\u016b\u0161i\u0173, o dalis j\u0173 aptinkama ir Juodojoje j\u016broje.<\/p>\n
Nors \u0161ie gyv\u016bnai da\u017eniausiai nepavojingi stebint i\u0161 tolo, kontaktas gali b\u016bti skausmingas. Gelian\u010diosios l\u0105stel\u0117s kai kuriems \u017emon\u0117ms sukelia odos sudirginim\u0105, tod\u0117l gamtoje patariama j\u0173 neliesti.<\/p>\n","protected":false},"excerpt":{"rendered":"
