Finned Battleship

The alligator gar is one of North America’s largest freshwater fishes. It can grow up to 10 feet long and weigh over 300 pounds.

Gar-mor

Alligator gar are wrapped in armor-like scales that are so hard and sharp Native Americans used them for arrowheads.

Armed to the Teeth

An alligator gar’s top jaw is spiked with two rows of pointy teeth. When this toothy trap snaps shut, even a slippery fish can’t slip out.

Mouth Breather

Gar use gills to breathe water, but they also gulp air at the surface. This lets them live in swamps and sloughs that don’t hold enough oxygen for other fish to survive.
