What this living fossil lacks in game appeal, it makes up for with tenacity and an astonishing natural history.

We’re picking our way through the braided back- waters of the Upper Mississippi River National Wildlife & Fish Refuge. There are no naviga- tional aids here, so we rely on a depth finder as we motor cau- tiously through a maze of chan- nels that weave between and around islands. Along the way, we pass a handful of anglers. They are likely fishing for bass, walleye, or panfish—all evo- lutionary newbies compared with gar, which have existed for 100 million years.

Asteroid Survivor During the Late Cretaceous, gar swam with guitarfish, sharks, paratarpon, and a host of other fish that either no longer ex- ist or no longer inhabit fresh- water. Tyrannosaurus rex and Triceratops roamed the land, and pterodactyls flew overhead. But, in the plodding context of geological time, nearly half of earth’s species were on the cusp of mass extinction. Sixty-six million years ago, an asteroid 10 kilometers in diame- ter slammed into what is now the Yucatan Peninsula of Mexico,

The fish continues its defi- ant routine for a minute or two before I’m able to lead this an- cient predator alongside the boat. The gar’s burnished silver and bronze flank sparkles with an olive sheen in the midday sun, and I find myself trans- fixed by its disproportionately large eyes. Somewhere behind the black porthole of its gold- rimmed pupils, a crackling engine of neurons hardwired for survival surveys me as a threat—with the same impulse for flight as its ancestors flee- ing from far larger, long-extinct creatures of the Cretaceous. Geving lifts the gar into the boat, and we work to prop its bill open to pick out the tangled rope. It’s a tedious process that is only partially within our control. At one point the gar convulses off the boat floor and bloodies Geving as it brushes its razor-sharp scales in a tail- to-head direction across his bare calf. We’re eventually able to free the fly. Before returning the fish to the river, I gaze again into one of its unflinching eyes.
