Pojasnici (Clitellata), razred kolutićavaca (Annelida) koji se sastoji od podrazreda pijavica (Hirudinea) i hermafroditskih maločetinaša (Oligochaeta).

Maločetinaši žive u vlažnoj zemlji, ali i u slatkim i morskim vodama, a najpoznatoije potodice su gujavice i glibnjače. Maločetinaši dišu kroz kožu ili stražnjim crijevom.[1]

Pijavice žive po ustajalim vodama kao paraziti koji oštrim hitinskim zubičima sišu krv puževima, rakovima i toplokrvnim životinjama, pa se neke od njih koriste i u medicini, Hirudo medicinalis,[2] koju je još 1758. opisao Linnaeus.
