  2. Zoology Gar fish have long jaws and pointy teeth to eat prey they are long and can grow to be 6 feet they have huge hard scales and are very similar to the alligators. Gar Family; Black gar Alligator gar Gator fish Belone gar

  3. Anatomist Contribution Gars are incredibly similar in the jaw and head area to alligators and crocodile Gar fish skull Alligator skull

  4. Paleontologist Contribution Present picture Prehistoric picture Back in the prehistoric days the Gar fish would grow up to 3 feet long and now the present day Gar fish grows to be 15.3 inches long

  5. Molecular Data (DNA) • The chromosomes of long nose gar, Lepisosteus osseus, an extant representative of early radiation of actinopterygian fishes, were studied using conventional Giemsa-staining, Ag-staining, CMA3-fluorescence and fluorescence in-situ hybridization (FISH). The diploid chromosome number was 2n = 56 and the karyotype contained 11 pairs of metacentric, 6 pairs of submetacentric, 3 pairs of subtelocentric macrochromosomes and 16 microchromosomes. Nearly all macrochromosomes showed large CMA3-positive regions resembling the R-bands of higher vertebrates, indicating extensive distribution of GC-rich DNA along chromosomes. • Scientific Classification • Kingdom: Animalia • Phylum: Chordata • Class: Actinopterygii • Order: Lepisosteiformes • Family: Lepisosteidae • Genus: Atractosteus • Species: Atractosteus spatula Classification of an alligator Kingdom- AnimaliaPhylum-chordataClass-reptiliaOrder-CrocodiliaFamily-AlligatoridaeGenus- Alligator( Daudin, 1809)Species 2 American- Alligator mississippiensis and Chinese- Alligator sinensis
