Worker Splinters are creatures that appear in Metroid Prime 2: Echoes. They are a breed of Splinter that is bred for service, not combat. They spend their time collecting food and material for the hive. They are found in the tunnel systems as opposed to the surface of Aether. Worker Splinters can spin a tensile webbing for use in storing food and constructing edifices for the Splinter hive.
Worker Splinters are insubstantial, spindly and almost transparent. They have light grey bodies with a weak carapace, and a cluster of eyes that is less pronounced than that of the predatory Splinter (possibly as a side effect of acclimation to a subterranean environment).
