  We consider the classical Holling-Tanner model extended on 1D space by
introducing the diffusion term. Making a reasonable simplification, the
diffusive Holling-Tanner system is studied by means of symmetry based methods.
Lie and Q-conditional (nonclassical) symmetries are identified. The symmetries
obtained are applied for finding a wide range of exact solutions, their
properties are studied and a possible biological interpretation is proposed. 3D
plots of the most interesting solutions are drown as well.
