The Grunzbarsche (Terapontidae) are a family of perch relatives (Percomorphaceae). Most of the species inhabit the fresh and brackish waters of Australia , New Guinea , Indonesia and the Philippines . Some species also live as schooling fish in the sea.
features
The fish are 8.5 to 54 cm long. Their body is elongated to oval, slightly flattened on the sides. There are two spines on the gill cover , the lower one of which is longer. The ploughshare and palatine bone of most species do not have teeth. The number of Branchiostegal rays is six. The sideline extends to the caudal fin. The hard and soft rayed part of the dorsal fin are separated by an indentation. The soft-jet part can be laid down in a pit formed by scales. The pelvic fins stand just behind the base of the pectoral fin. The caudal fin is indented or rounded.
Fins formula : dorsal XI – XIV / 8–14, anal III / 7–12, ventral I / 5.
The swim bladder is divided transversely (along the longitudinal axis of the body). Paired muscles that attach to the outside of the anterior chamber of the swim bladder extend toward the back of the skull. With their help, the fish can make sounds. Grunts have 25 to 27 vertebrae.
Systematics
There are about 65 described species in 16 genera and some undescribed species in isolated rivers in the Australian Kimberley region .

About 40 of the described species and 13 genera occur in Australian waters. The numerous species developed, among other things, due to the frequent fluctuations in sea level and the associated isolation of individual populations ( allopatric speciation ) during the cold and warm periods in the Pliocene and Pleistocene .
