These elongated torpedo-shaped ‘living fossils’ have long, broad snouts with two rows of sharp teeth in their mouths. Their scales are heavy and overlapping like chain mail, and their small fins are set far back near their abbreviated, irregular caudal (tail) fin. They generally grow to 6.5 feet long and over 100 pounds, but have been caught significantly larger. Numbers for alligator gar are dwindling due to habitat loss (they prefer wide, slow-moving rivers which are being dredged and restructured) and over-fishing, and are now protected in many areas.
