The Mochokidae are a family of catfishes (order Siluriformes) that are known as the squeakers or upside-down catfish (although not all species swim upside-down). Nine genera and about 200 species of mochokids are described. All the mochokids are freshwater species originating from Africa.
They have three pairs of barbels, with the nasal barbels absent; sometimes, the mandibular barbels may be branched.
