In some species the last pair of legs act in a similar means to antennae, except they face backwards. The organs of Tömösvary are an unusual feeling organ discovered only in some types of centipede. Lock are situated at the base of the antennae and are thought to be offered in sensing vibrations or perhaps offering a feeling of hearing.
