perciform fish grunter family Grunters or tigerperches are fishes in the family *Terapontidae* (also spelled *Teraponidae*, *Theraponidae* or *Therapontidae*). They are found in shallow coastal waters in the Indian Ocean and western Pacific, where they live in saltwater, brackish and freshwater habitats. They grow up to 80 cm in length and feed on fishes, insects and other invertebrates. When caught, grunters make the characteristic grunting sounds that give them their name.
