Longnose Gar
Longnose Gar are primitive fish that have existed for about 100 million years, making them living fossils in North Dakota's waters.
Scientific Name: Lepisosteus osseus
- They're characterized by their olive brown to green, torpedo-shaped bodies armored with diamond-shaped ganoid scales, and distinctive elongated jaws that form a needle-like snout nearly three times the length of their head.
- These snouts are filled with numerous sharp, cone-shaped teeth designed for gripping rather than slicing prey.
- They typically grow 28-48 inches with maximum lengths around 6 feet and weights up to 55 pounds.
