Boating up the headwaters of the Amazon, diving in the frigid waters of Mongolian rivers or warm Australian rivers, Zeb Hogan travels the globe to find the biggest freshwater fish on the planet. In the last Discover Science Lecture Series presentation of the school year at 7 p.m., Thursday, May 7, he will talk about his adventures, travels and work to find, study and protect behemoth fish, fish that are more than 6 feet long or weigh more than 200 pounds.

This event is open to the public and school-aged children are encouraged to attend.

"People are really interested in these big fish, but some of my most animated audiences are the children," Hogan, University of Nevada, Reno researcher and host of National Geographic's "Monster Fish" show said. "They ask the most fun questions, and really surprise me with what they are curious about. It will be a sciencey talk for adults, but kid-friendly."

Now in its fifth year, the annual Discover Science Lecture Series brings renowned scientists from around the country to share their knowledge with the community.

"Science encompasses a wonderfully diverse collection of explorations into the unknown," Jeff Thompson, dean of the College of Science, said. "We want our community to experience the extent of the science universe as the best scientists on the planet visit Nevada for our Discover Science Lecture Series."

The lecture is held at 7 p.m. in the Redfield Auditorium in the Davidson Mathematics and Science Center on the University campus. Parking is reserved for the event on the top level of the Brian J. Whalen Parking Complex on North Virginia Street. Admission is free. For more information, call 775-784-4591 or visit the College of Science website.
