Description
The Whitetongue Jack is a large, predatory marine fish characterized by its silvery body and a distinctive white or pale tongue and mouth lining. It forms schools in open water and near reefs, actively hunting smaller fish and invertebrates. Due to its size and predatory nature, it is primarily suited for very large public aquariums.
