Answer:
Moving objects in fluid must have special shapes because the drag force or the friction force depends of the shape of the object. Special shapes are designed to minimize the opposing frictional force.

what is drag ?
Drag is the aerodynamic force that opposes an aircraft's motion through the air. Drag is generated by every part of the airplane (even the engines!). ... Drag is generated by the difference in velocity between the solid object and the fluid. There must be motion between the object and the fluid.
why object moving in fluid must have special shape? explain
Objects moving in fluids face the friction of the fluid that opposes their motion. So Objects moving in fluids must have unique shapes called streamlined shapes to reduce the fluid friction.
