Summary
Two types of sensory neurones are located in the mandibles, antennae, labrum, labium and maxillipeds of the brackish water calanoid copepod Gladioferens pectinatus: a ciliary type and a nonciliary type. These occur either separately in different sensilla or sometimes both are present in the same sensillum. These sensilla appear to be similar to the mechanoreceptors and chemoreceptors found in insects. The structure of the sensilla is described here and they are briefly compared with the sensory receptors of other arthropods. It is suggested that the sensilla in the mandibles and the labrum aid the animal in selective filter feeding.
