Take a look at this photograph. It looks like the cross section of a tooth, but it’s actually a thin slice of a paddlefish jaw. The jaws of paddlefish contain rings, just like trees, showing annual growth. Montana Fish, Wildlife & Parks takes jaws from paddlefish harvested in Montana to keep track of the fishes’ numbers, ages and population. Paddlefish are a unique species and grow large, making them a target for spring anglers.
