The National Geographic Museum’s new exhibit, Monster Fish, had its grand opening on Friday. The exhibition takes visitors deep into the world of, and face-to-face with, the world’s most peculiar and menacing fresh water creatures. Dr. Zeb Hogan, an aquatic ecologist and National Geographic fellow spent a decade searching for the world’s largest freshwater fish, and many of his exploits were filmed for National Geographic’s television show, Monster Fish. But, the show was only one aspect of Hogan’s work and the new exhibit provides a space to showcase new items. The exhibit (divided into four geographical regions) is kid-friendly, and provides fun for all ages. Interactive games and videos are scattered throughout, with life-size fish sculptures at every turn. One particular notable element is the exhibit’s giant scale. Families can stand on it together and see which fish their collective weight equates to. Additionally, visitors will learn how explorers can deduce a fish’s age by looking at its remains, and how to virtually tag a fish and learn about its movement. The exhibit costs $11 for adults, $7 for kids, and free for 4 and under. Monster Fish will be at the National Geographic Museum through October 11, 2015.
