Longnose gar, Lepisosteus osseus, are fish that are found from the Northern most great lake to the Mississippi delta and almost every river and lake in between (Goddard). With a habitats range that is so diverse, one might assume that longnose gar are a type of super adaptive organism that is fresh faced to this world. This however could not be further from the truth. In fact longnose gar are referred to as “living fossils” by multiple sources because its lineage has been traced back over 100 million years (“Large unusual fish,”). However due to the fact that the longnose gar is such an old species very few other fish can be classified in the same category as it.
