Numerical techniques are employed to study the locomotion of a spheroidal squirmer in a complex fluid with a nutrient-dependent viscosity. It is found that the nonuniform viscosity significantly affects the pressure field around the swimmer rather than the velocity field. Results obtained here will be helpful in interpreting experimental observation where a microswimmer significantly affects a fluid's local rheology.
