They spawn in temperatures close to 20 Â°C (68 Â°F) in late April to early July. Eggs have a toxic, adhesive coating to help them stick to substrates, and they are deposited onto stones in shallow water, rocky shelves, vegetation, or

Longnose gar have a typical lifespan of 15–20 years with a maximum reported age of 39. This long lifespan allows the female to sexually mature around 6 years old. Males mature sexually as early as 2 years of age. Longnose gar are sexually dimorphic; the females are larger than the males in body

Their populations are stable and in some areas abundant in the interior portions of their range. 648:, elongated jaws that form a needle-like snout nearly three times the length of its head, and a row of numerous sharp, cone-shaped teeth on each side of the upper jaw.
