From a two-headed duckling to a full human skeleton to pickled snakes and mice, the hundreds of items in Joanna Ebenstein's collection of curiosities meet at the intersection of art, science, death and beauty.

The 42-year-old's personal collection of taxidermy, anatomical art and ephemera have been known as the Morbid Anatomy Library inside Brooklyn's Proteus Gowanus gallery since 2008.

But come April, she'll bring her passions to a larger audience when the Morbid Anatomy Museum opens in a 4,200-square-foot, three-floor space in Gowanus.

"The Morbid Anatomy Museum is going to collect objects that tell that interesting, somewhat eccentric and lesser-told story," said Evan Michelson, a museum board member, antiques dealer and star of the Science Channel's reality TV show "Oddities."

Museum Chief Executive Tracy Hurley Martin agreed, saying mainstream exhibits won't be a part of the space, which will include an expanded permanent collection of curiosities, an exhibition space, lecture areas, a cafe and a gift shop.
