No. There is no hard, inflexible exoskeleton. The starfish skin has hard protuberances called ossicles, in the form of small plates and spines, which offers most species some protection. The only way a starfish can become smaller is through extreme starvation, disease, or losing one or more arms to a predator. In many starfish, the arms will regrow.
