The grunts are a family, Haemulidae, of fishes in the order Perciformes. They are numerous and widespread, with about 150 species in 19 genera, found in tropical fresh, brackish, and salt waters around the world. They are bottom-feeding predators, and named for their ability to produce sound by grinding their teeth. They also engage in mutualistic relationship with cleaner gobies of genus Elacatinus, allowing them to feed on ectoparasites on their bodies.
