Crayfish have peripheral nerve fibres [44] which are responsive to noxious stimuli. [ 42 ] Neurons functionally specialized for nociception have been documented in other invertebrates including the leech Hirudo medicinalis , the nematode Caenorhabditis elegans and the molluscs Aplysia californica and Cepaea nemoralis .
