Small cladoceran crustaceans, such as Sida crystallina, attach themselves to the substrate by adhesive anchors connected to the cuticle. S. crystallina bears three anchor organs at the dorsal side of the head. An animal attaches to an anterior organ first, and then additionally attaches to two movable posterior organs. The attachment is presumably due to a cementing secretion, because fine threadlike structures remain attached to the substrate even after the animal frees itself [107]. However, the nature of this secretion and the strength of attachment remain unknown.
