In lacul Mangalia trăieşte o specie de peşte care naşte pui vii. Cum se numeşte specia respectivă şi fenomenul ?

Specia de peşte care trăieşte în lacul Mangalia se numeşte gambuzie (Gambusia affinis), iar însuşirea de a naşte pui vii - viviparitate. Pe tot globul se cunosc actualmente 200 de specii vivipare.

Dar e interesant ca se intampla asa ceva la pesti, lucru deloc comun. Oare ce sistem reproducator au? :-?
