This sultry siren is quite the catch yesterday at Coney Island’s Mermaid Parade — where crowds ogled mermen and maidens on Surf Avenue.

The 31st annual procession nearly went extinct after Hurricane Sandy, but $117,000 was raised to keep it afloat.

Judah Friedlander of “30 Rock” reigned as King Neptune, and Real Housewife Carole Radziwill was Queen Mermaid.
