A light and electron microscope study of intra-epithelial putative mechanoreceptors in squid suckers

Putative mechanoreceptor neurons in the cuticularized epithelium of the suckers of the squid Lolliguncula brevis, were investigated using light and electron microscope techniques. These neurons were found to have a multipolar shape, thick unbranched axon, glial cell ensheathment, and accessory nerve fiber innervation. The need for electrophysiological and/or behavioral studies on these putative mechanoreceptors is emphasized.
