Alligator Gar 鳄鱼火箭 5"
Common Name: Alligator Gar
Scientific Name: Atractosteus Spatula
The body of an alligator gar is torpedo-shaped, usually brown or olive fading to a lighter gray or yellow ventral surface. Their scales are not like the scales of other fishes; rather, they are ganoid scales which are bone-like, diamond-shaped scales, often with serrated edges, and covered by an enamel-like substance. Ganoid scales are nearly impenetrable and are excellent protection against predation. Unlike other gar species, the upper jaw of an alligator gar has a dual row of large, sharp teeth which are used to impale and hold prey. Alligator gar are stalking, ambush predators, primarily piscivores.
