From the microscopic to the massive, the Academy’s newest exhibition provides an unprecedented peek at some of the standout specimens from our scientific collections—including some on view for the very first time.

Nearly 40 thousand animals are on exhibit at the Academy. But did you know there are nearly 46 million specimens behind-the-scenes?

Hidden Wonders: Inside the Academy’s Collections offers a look into the Academy’s vast “library of life,” an archive of objects from around the world and across the eons. With nearly 800 fascinating specimens on display, guests will learn why scientists and museums collect, and how collections are an invaluable, irreplaceable resource for conserving and regenerating the natural world.

A specimen’s legacy

Hidden Wonders invites guests to follow a specimen’s path from observation to analysis to preservation to see firsthand how collections are built—and how the legacy of a specimen extends far beyond its lifetime. The exhibition also highlights the tools and technologies that enable our scientists to extract DNA from specimens collected long ago.

Collecting is conserving

By understanding the past, we can protect the future. Our scientific collections are a vital record of our planet’s natural history, allowing scientists and researchers to track the spread of disease over time, predict the impact of climate change on species and ecosystems, help prevent future extinctions, and more.

The deeper you go, the bigger things can get. Case in point: The giant isopod (Bathynomus kensleyi). Superficially resembling a super-sized pill bug, this crustacean scavenges the seafloor at depths of 560-8,200 feet and can grow up to 14 inches long. This particular specimen was collected by Academy scientists during a 2011 Philippines expedition.
