The hydrodynamic modes of a generic magnet, either classical or quantum, are diffusive fluctuations of spin and energy density. We illustrate various ways in which this conventional understanding breaks down in quantum magnets. In one dimension, we discuss how exact or approximate integrability can lead to anomalous, superdiffusive transport of spin or energy. In more than one dimension, we argue that magnets near a low-temperature spin liquid phase can support additional hydrodynamic modes compared to their high-temperature paramagnetic phase, which arise from emergent gauge and flavour symmetries of the spin liquid state.
