Dissipative solitons, self-sustained localized structures that emerge in nonlinear systems, have attracted significant attention in various fields of physics of fluids. In this paper, we investigate the existence and properties of dissipative solitons in a superthermal plasma having superthermal electrons and in the presence of pressure anisotropy. We develop a theoretical model based on a set of coupled nonlinear equations that describe the evolution of plasma density and electromagnetic fields. The model incorporates the effects of nonlinearity, dissipation, and the anisotropic nature of the plasma pressure. Our results reveal that the superthermal plasma with pressure anisotropy can support the existence of compressive dissipative solitons. We find that anisotropic pressure can influence the formation, lifetime and spatial structure of the solitons. The present investigation could be useful in space and astrophysical plasma systems, laboratory plasmas and fusion research.
