Marea Neagr\u00e3 este o mare intracontinental\u00e3, situat\u00e3 \u00eentre Europa de Sud-Est \u015fi Asia Mic\u00e3 \u015fi se \u00eenvecineaz\u00e3 cu Rusia, Ucraina, Rom\u00e2nia, Bulgaria, Turcia \u015fi Georgia. Prin Str\u00e2mtoarea Kerci se ajunge \u00een Marea Azov, prin Bosfor \u00een Marea Marmara, iar prin str\u00e2mtoarea Dardanele \u00een Marea Egee \u015fi mai apoi \u00een Mediteran\u00e3. Ea este un rest al M\u00e3rii Sarmatice \u015fi prezint\u00e3 o serie de aspecte unice \u00een lume, motiv pentru care mai este numit\u00e3 unicum hydrobiologicum.
\nAre o suprafa\u0163\u00e3 de 413.000 km2, cu ad\u00e2ncimile cresc\u00e2nde p\u00e2n\u00e3 la 2245 m. Unicitatea se refer\u00e3, \u00eentre altele, la existen\u0163a vie\u0163ii numai p\u00e2n\u00e3 la 180-200 m ad\u00e2ncime, pe a\u015fa-numita platform\u00e3 continental\u00e3, care \u00een dreptul litoralului rom\u00e2nesc este cea mai extins\u00e3. Mareele sunt \u00een general de mic\u00e3 amploare (cca. 12 cm). Salinitatea apei este \u00een larg de 15-22 g la litru, fa\u0163\u00e3 de 24-34 g\u2030, \u00een alte m\u00e3ri \u015fi oceane. \u00cen zona litoralului rom\u00e2nesc salinitatea scade \u015fi mai mult, \u00een mod obi\u015fnuit fiind \u00eentre 7 \u015fi 12 g\u2030.
\nMarea Neagr\u00e3 adun\u00e3 la un loc apele mai multor r\u00e2uri \u015fi fluvii ce apar\u0163in Europei \u015fi Asiei. \u00cen zona european\u00e3 principalele sunt Dun\u00e3rea, Nistrul, Niprul, Bugul de Sud \u015fi Cubanul. \u00cen Asia Mic\u00e3 principalele ape care se vars\u00e3 \u00een Marea Neagr\u00e3 sunt Scaria, Enige, Chizil-Irmac \u015fi Ie\u015fil-Irmac. Alte ape care se vars\u00e3 \u00een Marea Neagr\u00e3 sunt Coruh \u00een Armenia turceasc\u00e3, Rion, \u00een Gruzia, Provadia \u015fi Camcia \u00een Bulgaria etc. De un aport mare de ap\u00e3 beneficiaz\u00e3 Marea Neagr\u00e3 de la Don, prin intermediul M\u00e3rii Azov.
\nDispunerea circular\u00e3 a surselor de ap\u00e3 \u015fi existen\u0163a unei singure leg\u00e3turi externe – prin Str\u00e2mtoarea Bosfor cu Marea Marmara \u015fi prin Str\u00e2mtoarea Dardanele cu Marea Mediteran\u00e3 \u015fi Oceanul planetar, al\u00e3turi de \u00eenc\u00e3lzirea relativ moderat\u00e3 a apei de c\u00e3tre Soare, determin\u00e3 lipsa aproape total\u00e3 a curen\u0163ilor marini verticali \u015fi existen\u0163a doar a curen\u0163ilor orizontali pe un imens traseu circular, ce se mi\u015fc\u00e3 \u00een sensul invers al acelor de ceasornic (N-E-S-V).
\nDin punct de vedere al salinit\u00e3\u0163ii, Marea Neagr\u00e3 se \u00eemparte \u00een zona de suprafa\u0163\u00e3 \u015fi zona de ad\u00e2ncime, iar sub aspect biocenotic g\u00e3sim trei zone: litoral\u00e3, pelagic\u00e3 \u015fi abisal\u00e3.
\nTemperatura apei variaz\u00e3 la suprafa\u0163\u00e3: vara p\u00e2na la 290C, iarna ajunge la 00C. Lumina p\u00e3trunde \u00een largul m\u00e3rii la o ad\u00e2ncime de 150-200 m. Sub aceast\u00e3 ad\u00e2ncime nu exist\u00e3 oxigen, din cauza unui strat de bacterii sulforeduc\u00e3toare, care produc bioxid de carbon \u015fi hidrogen sulfurat. Iarna sau \u00een timpul unor varia\u0163ii ale st\u00e3rii vremii, se pot forma valuri \u00eenalte de 5-10 m.
\nFauna este reprezentat\u00e3 \u00een principal prin viermi, molu\u015fte, crustacee, pe\u015fti \u015fi delfini, \u00een mediul acvatic \u015fi p\u00e3s\u00e3ri consumatoare de pe\u015fti, \u00een cel aerian din vecin\u00e3tatea \u015fi deasupra bazinului pontic.<\/p>\n

\u00cen fauna marin\u00e3 din Marea Neagr\u00e3 putem \u00eent\u00e2lni:
\n– C\u00e3lu\u0163ul de mare (Hypocampus hypocampus) – ilustrat pe timbrul cu valoarea nominal\u00e3 de 70 de bani.
\nC\u00e3lu\u0163ul de mare vie\u0163uie\u015fte printre tufele de iarb\u00e3 de mare \u015fi printre alge, la o mic\u00e3 distan\u0163\u00e3 de \u0163\u00e3rm. Acest pe\u015fti\u015for ce pare o pies\u00e3 de \u015fah, m\u00e3soar\u00e3 10-12 cm. Interesant e c\u00e3 puii se dezvolt\u00e3 \u00eentr-o pung\u00e3 situat\u00e3 sub abdomenul masculului, de unde, dupa 2-3 s\u00e3pt\u00e3m\u00e2ni, se r\u00e3sp\u00e2ndesc \u00een apa m\u00e3rii. C\u00e3lu\u0163ul de mare \u00ee\u015fi poate schimba culoarea corpului pentru a se adapta mediului \u015fi a se feri de du\u015fmani.
\n– Delfinul comun (Delphinus delphis) – ilustrat pe timbrul cu valoarea nominal\u00e3 de 1,50 lei.
\nDelfinul comun are spatele cenu\u015fiu-negricios, cu reflexe verzui. Laturile corpului sunt cenu\u015fii, iar abdomenul albicios. Botul este potrivit de alungit, mandibula dep\u00e3\u015fe\u015fte maxila, iar fruntea este pu\u0163in turtit\u00e3 \u00een partea anterioar\u00e3. Se hrane\u015fte cu crustacei, molu\u015fte cefalopode, dar um\u00e3re\u015fte \u015fi c\u00e2rdurile de sardele, hamsii, pe\u015fti zbur\u00e3tori (\u00een Mediteran\u00e3). Are o lungime cuprins\u00e3 \u00eentre 1,5-1,8 m \u015fi o greutate de p\u00e2n\u00e3 la 55 kg (\u00een cazuri excep\u0163ionale, ajunge la 100 kg). Durata maxim\u00e3 de via\u0163\u00e3 a indivizilor speciei este de 22 de ani (masculi) \u015fi 20 de ani (femele). Tr\u00e3ie\u015fte de-a lungul coastei, la ad\u00e2ncime mic\u00e3.
\n– \u021aestoasa de mare (Caretta caretta) – ilustrat\u00e3 pe timbrul cu valoarea nominal\u00e3 de 3,10 lei.
\nAceast\u00e3 specie mai rar \u00eent\u00e2lnit\u00e3 la noi, are talia \u00een general mare, astfel c\u00e3 adul\u0163ii pot atinge chiar 1,2 m \u015fi o greutate de p\u00e2n\u00e3 la 200 kg. De regul\u00e3, \u0163estoasa de mare tr\u00e3ie\u015fte \u00een Oceanul Atlantic, Marea Mediteran\u00e3, rareori p\u00e3trunz\u00e2nd \u015fi \u00een Marea Neagr\u00e3, de unde poate ajunge accidental \u015fi \u00een apropierea plajelor rom\u00e2ne\u015fti. Are capul mare, maxilarele puternice, iar membrele anterioare sunt sub form\u00e3 de palet\u00e3 \u015fi prev\u00e3zute cu doua gheare. Este omnivor\u00e3, hr\u00e3nindu-se cu pe\u015fti \u015fi alte animale marine.
\n– R\u00e2ndunica de mare (Trigla lucerna) – ilustrat\u00e3 pe timbrul cu valoarea nominal\u00e3 de 7,70 lei.
\nR\u00e2ndunica de mare este un pe\u015fte marin rar, ce masoar\u00e3 \u00een jur de 65 cm \u015fi c\u00e2ntare\u015fte aproape 3 kg. Are corpul viu colorat, acoperit cu solzi mici. \u00cenot\u00e3toarele pectorale, care sugereaz\u00e3 forma aripilor de r\u00e2ndunic\u00e3, se prelungesc asemenea unor gheare \u00eendoite, cu ajutorul c\u00e3rora pe\u015ftele se poate \u015fi t\u00e2r\u00ee pe fundul m\u00e3rii. Datorit\u00e3 culorilor sale vii, r\u00e2ndunica de mare este una din cele mai frumoase specii de pe\u015fti din Marea Neagr\u00e3.<\/p>\n
