Description
The Threadfin Jack is a large, predatory marine fish known for its distinctive elongated dorsal and anal fin rays, especially as juveniles. As they mature, these rays shorten, and the fish develops a more typical jack-like, compressed body shape. Due to their immense size and rapid growth, they are primarily suited for public aquariums.
