Characins, or Characidae, are characterized by two main features: Weberian Apparatus and adipose fins. A Weberian apparatus is a series of bony parts connecting the swim bladder and inner ear. Characins appear similar to their relatives, the Cyprinids, but have a small fleshy adipose fin between the dorsal fin and tail. As Characins are often carnivorous, they have teeths within their mouths. Characins also have well-defined scales. Their mouths are not fully extendible.
