Rechinul alb , Carchrodon carcharias , cunoscut drept \u201c Marele Alb \u201d este probabil cel mai faimos din specia rechinilor . Apartine unei familii de rechini cunoscuti drept inotatori rapizi numiti rechini \u201c mackerel \u201c si este cel mai mare carnivor de pe pamant , din zilele noastre , in afara de cei care se hranesc cu plancton , cum ar fi balena . Cel mai mare rechin prins vreodata avea 6.4 metri si cantarea 3312 kg . Stramosii lui erau de trei ori mai mari si aveau dinti de 16 cm .
\n In afara de petele albe si de marimea lor rechinii albi pot fi identificati dupa forma dintilor lor , asta daca cineva are curajul de a se apropia atat de mult . Dintii de pe falca inferioara sunt folositi pentru a apuca si tine prada . Dintii in forma triunghiulara de pe falca superioara sunt folositi pentru a sfasia . In spatele acestui sir de dinti se afla multe alte siruri . Atunci cand un dinte din fata este pierdut el este imediat inlocuit de un dinte din sirurile celelalte . Se cunoaste foarte putin despre modul de reproducere al rechinului alb . Recent a fost examinata o femela insarcinata . Sezonul reproducerii este necunoscut ; se pare a fi perioada primavara-vara . Se credea ca o femela face cam doi pui dar s-a descoperit ca numarul acestora este cuprins intre 9 si 11 . Nasterea nu a fost nuciodata vazuta sau studiata . Rechinii albi sunt ovovipari , ceea ce inseamna ca ei poarta oua in interiorul corpului lor pana cand puii sunt nascuti . Acestia sunt nascuti vii , perfect formati si pregatiti de a vana . Puii rechinului alb pot avea 1.4 metri si sunt dotati cu o dantura completa. Fiind un peste cu o raza de actiune mare rechinul alb traieste atat in Oceanul Pacific , cat si in oceanele Atlantic si Indian , de la tropice pana la cercurile polare. Acest rechin este gasit de obicei in apele adanci ale platformei continentale . Ochii rechinului sunt formati pentru vederea diurna si majoritatea atacurilor le da in timpul zilei . Oamenii il considera unul din cei mai peiculosi rechini datorita marimii sale , comportamentului agresiv si obiceiului de a inota si in apele mai putin adanci in cautare de hrana . Scufundatori si inotatori au fost atacati de acest rechin , insa se pare ca .acesta nu este chiar atat de rau pe cat a fost descris in filmul \u201cJaws \u201c . Unii scufundatori au afirmat ca este o creatura timida care fuge la apropierea omului . Este un pradator lacom si de temut . Prada sa consta intr-o larga varietate de pesti ososi , alti rechini , pasari de mare broaste testoase de mare , mamifere marine cum ar fi focile , leii de mare , vidrele si altele . Strategia sa consta intr-un atac surprinzator si rapid din spate , provocand o rana mare . Cel atacat de cele mai mule ori moare datorita traumei sau a pierderii de sange , insa muscaturile pot fi si superficiale sau plasate gresit pe corpul prazii , ingaduindu-i sa supravietuiasca atacului si sa scape doar cu cateva cicatrici . Cercetari recente ne arata ca rechinului alb ii displace a se hrani cu carnea omului . Rechinii albi prefera carnea grasa , bogata in calorii , asa ca o slabatura de om nu se poate compara cu o foca \u2013 elefant . Chiar si asa rechinul alb trebuie respectat si evitat . Numarul de rechini albi a scazut in ultimul timp astfel incat ocrotirea acestui animal a devenit o noua preocupare . Pana acum California , Africa de Sud si Australia au dat legi care ocrotesc aceste fascinante animale de a fi vanate irational . Sa speram ca mai multe natiuni isi vor uni fortele pentru a proteja \u201c marele rechin alb \u201c astfel incat oamenii de stiinta sa-I poata studia comportamentul unic si fascinant .<\/p>\n
