Freshwater Gar
Freshwater Gar
A little synchronized swimming demonstration by two Freshwater Gar (or Garpike) in a marine display at Cabella’s in Kansas City. OK, they weren’t actually performing, I just happened to catch two gliding by, side by side.
According to Wikipedia: Gar bodies are elongated, heavily armored with ganoid scales, and fronted by similarly elongated jaws filled with long, sharp teeth. Their tails are heterocercal, and the dorsal fins are close to the tail. As their vascularised swim bladders can function as lungs, most gars surface periodically to take a gulp of air, doing so more frequently in stagnant or warm water when the concentration of oxygen in the water is low. They also appear to surface in fast-moving rapids. As a result, they are extremely hardy and able to tolerate conditions that would kill most other fish.
This was a difficult image to capture. The scene wasn’t as bright as it looks here. In order to get this shot at f/6.7 I had to kick up the ISO to 3200 and the shutter speed down to 1/20tth of a second. Of course, handheld with no flash through. I don’t think I’ve ever shot at ISO 3200 before. (Even in low light conditions, I try to keep the ISO no higher than 800.) If you look closely, you’ll notice the image is not quite as sharp as I’d like and there’s a bit of digital noise…but not enough to discard the image.
