Genes involved in chemoreception and immune response are overrepresented. It may also be a site of oxygen chemoreception. Like olfaction, taste requires a process of chemoreception. The rhinophores are classified as sensory organs for the act of chemoreception. Starfish can locate their prey by chemoreception. They are primarily used for distance chemoreception and rheoreception (response to water current). These are well supplied with nerve cells and are probably chemoreception organs. Ependyma and tanycytes may also participate in chemoreception. Sensory function includes both tactoreception (touch) and chemoreception (smell or taste). Smell, or olfaction, is a chemoreception that forms the sense of smell. Hunting females mainly use vision but antennal chemoreception plays some role. The male has enlarged aesthetes (found on the antennules), which are likely used for chemoreception. Olfaction is a chemoreception that, through the sensory olfactory system, forms the perception of smell. She co-founded the Association for Chemoreception Sciences (ACHEMS), and the Sensory Reception Scholarship Fund (SSSF). Chemoreception is important for the detection of food, habitat, conspecifics including mates, and predators.
