The goliath tigerfish has a characteristic silvery gray dorsum and flanks, with a tunniform body plan similar to that of tuna, featuring black adipose fins. The goliath tigerfish is described as the "Monster Fish of the Congo" by a 2008 documentary by National Geographic, a reflection of its monster-like qualities and of its perception by local people and hunters.
The upper jaw, or maxilla [12] [13] is a fusion of two bones along the palatal fissure that form the upper jaw. This is similar to the mandible (lower jaw), which is also a fusion of two halves at the mandibular symphysis. In bony fish, the maxilla is called the "upper maxilla," with the mandible being the "lower maxilla".
Datnioides undecimradiatus has the toothless palatine and vomer characteristic of the tiger perches, as is the rounded caudal fin is rounded and rounded lobes on the anal and second dorsal fins creating the appearance of having three caudal fins. [7]
The Siamese tigerfish has the toothless palatine and vomer characteristic of the tiger perches, as is the rounded caudal fin is rounded and rounded lobes on the anal and second dorsal fins creating the appearance of having three caudal fins. [9] This species has 4, occasionally 5, wide vertical bars on the orange-brown body.

Most fish species with pharyngeal teeth do not have extendable pharyngeal jaws. A particularly notable exception is the highly mobile pharyngeal jaw of the moray eels.These are possibly a response to their inability to swallow as other fishes do by creating a negative pressure in the mouth, perhaps induced by their restricted environmental niche (burrows) or in the air in the intertidal zone.

Datnioides tiger perches are characterised by having toothless palatine and vomer. The caudal fin is rounded and there are rounded lobes on the anal and second dorsal fins creating the appearance of having three caudal fins. The dorsal fin is supported by 12 spines and 15 or 16 soft rays. [4]
