Every biologist has an origin story. A series of events and people that move us along a path toward the study of living things. For me, reading about a “dinosaur fish” in a children’s nature magazine basically changed my life.
I’ve always been interested in “creatures.” Snakes, frogs, insects, dinosaurs: the more unusual (and in many cases, underappreciated) the better.
Growing up, I’d sit wide-eyed listening to my grandparents’ fascinating stories about Indian wildlife; cobras were my favorite. My parents took me to ponds where I caught turtles, and zoos, where I lived at the reptile house, and museums, where I stood in awe of T-Rex. I chased praying mantises instead of playing kickball at sixth grade recess. Creatures.
Shortly after moving to Ohio at age 11, some neighborhood kids quickly recognized my interest in wildlife and gave me some old nature magazines. Ranger Rick. A kids’ magazine published by the National Wildlife Federation featuring animal stories guided by a raccoon mascot of the same name. Many of you are probably familiar with it; the magazine has been around for more than 50 years.
One day while leafing through a well-worn issue, I flipped the page and something caught my eye: a small illustration of two softshell turtles. At the time, my favorite animals were freshwater turtles, and anything about them commanded my attention.
But when I zoomed out beyond the tiny turtles, I saw the focus of this two-page spread was something else. Something ancient and beastly, like an alligator with fins instead of legs. It was a giant fish called an alligator gar.
My curiosity was piqued by this new “discovery,” its prehistoric appearance, armored scales, and huge jaws with lots of teeth. It reminded me of an aquatic dinosaur. I forgot about the turtles and proceeded to read the short story, “The Mississippi King,” about one of North America’s largest freshwater fishes, and how their lineage has been around since the dinosaurs. This stealthy predator could grow over six feet long, weigh more than 200 pounds, and it breathed air. I was instantly hooked on gars.
As an 11-year-old kid with an ever-expanding interest in all things “creature,” I at some point lost sight of those dinosaur fish. I went back to the turtles. By high school, I even lost that Ranger Rick magazine, but the image of the infamous Mississippi King remained emblazoned in the back of my mind for many years to come.
By my junior year as a pre-med biology major at Ohio Northern University, I had “sneaked” classes like invertebrate zoology and biological photography into my schedule, alongside requirements like human anatomy and physiology. I realized field biology was where my true passion resided, not pre-medicine. I decided to attend graduate school and planned to study herpetology (reptiles and amphibians), including the turtles I’d been fond of growing up.
The following year, however, I took a class called ichthyology (biology of fishes), and my biological focus shifted again. I wanted to study fishes. I was good at identifying and catching them; and fish diversity, particularly in freshwater, fascinated me.
Nearly half of the approximately 32,000 described fish species live in less than 1% of the world’s water. My ichthyology professor was especially fond of an unusual fish; he even had a decal of one on the university field truck. An elongate animal that looked like an alligator with fins instead of legs. Professor Keiser was a fan of gars, and then I recalled that I was too. We never caught a gar in that ichthyology class, but I did well studying other species and earned an A in the course. And I remembered the gars. What cool fish.
I dove deep into all things gar while in graduate school: gar conservation, gar aquaculture. I even kept gars in aquariums at my apartment. I learned that gars had an undeserved, bad reputation. Anglers often called gars “trash fish,” and they were often killed to “protect” more desirable sport fish like bass. Sometimes gars were simply target practice for bowfishers. Through my research and science communication, I wanted to show people that gars were valuable components of native ecosystems, not trash fish.
Several years later, I became an assistant professor of biological sciences at Nicholls State University in Louisiana, where I started GarLab. Our team studies the ecology and conservation of freshwater fish biodiversity, with a primary focus on, you guessed it, gars. I’ve shared my Ranger Rick “origin story” of being inspired by a fish tale in a kids’ nature magazine and making a career of studying (and defending) these unusual fish.
But there was still another chapter in this story.
Earlier this year (February 2020), Ranger Rick published another story, again with a big alligator gar spanning two pages, but this time the article was written by me. Although the story’s primary focus was the natural history of these living fossil fishes, Ranger Rick’s editors titled it “The Gar Guy” and made sure I incorporated my personal connection with these fishes and the article that started it all.
It’s been a dream come true, and it’s the publication I am most proud of. I hope the latest Ranger Rick gar story helps inspire a new generation of young people to learn more about the natural world, including an appreciation for those lesser-known, unusual “creatures.”
An avid fan of “primitive fishes” and advocate for native fishes conservation, Dr. Solomon David strives to effectively communicate science to both the research community and general public. Solomon is an aquatic ecologist and assistant professor of biological sciences at Nicholls State University in Louisiana, where his current research focuses on the ecology of migratory and ancient fishes (e.g. gars and bowfins). His graduate research at the University of Michigan focused on conservation ecology of Great Lakes fishes, including projects on Lake Trout, Chinook Salmon, and Spotted Gar. Solomon has also conducted postdoctoral research in fish ecology at the University of Wisconsin-Madison, Shedd Aquarium, U.S. Geological Survey, and Michigan State University.
