Monster Fish: In Search of River Giants

The legends are real...

Take a deeper dive into the hidden world of some of the world’s largest freshwater fishes inside “Monster Fish: In Search of the Last River Giants,” a National Geographic exhibition. This special exhibition, which is free with Aquarium membership or general admission, is located in the River Place building (adjacent to the Aquarium’s ticketing center) now through April 16.

Enormous in size and rapidly dwindling in number, these ancient fish play critical roles in their freshwater habitats. Dr. Zeb Hogan, aquatic ecologist, National Geographic Fellow and host of the Nat Geo WILD series “Monster Fish,” has spent nearly two decades searching for and studying the rare, large freshwater fish species profiled in the exhibition.

From the cold, rushing waters of the Himalayas, to the steamy, dark backwaters of the Amazon rain forest, Hogan’s adventures peel back centuries of myth surrounding these legendary animals and shed new scientific light on their unique morphology and behaviors.

Stunning life-sized sculptures, hands-on interactive exhibits, and videos from the field put you face-to-face with more than 20 species – each at least six feet long and weighing more than 200 pounds. Some of these replica creatures, like the super-sized sawfish, are climbable.

Themed areas of this new exhibition provide guests with opportunities to learn about how monster fish grow, how scientists study them, and how anglers and other individuals can help fish survive. 

After visiting, you’ll leave knowing which of the legends are real...and where there may be something VERY BIG lurking just beneath the surface.

Hogan’s Nat Geo WILD series “Monster Fish,” is now in its sixth season. In each episode, Hogan immerses himself in a local culture, where fishing is often more than a sport or even a profession — it’s a way of life. He tastes the regional cuisine, mingles at fish markets, listens to the harrowing stories of native fishermen and sleeps where his local guides do.
