| Abstract: | The general morphology, function and histology of the globiferous pedicallariae of the regular sea-urchin, Psammechinus miliaris are described. There is a ganglion under the sensory epidermis on the inner surface of each jaw. This is the first discovery of a ganglion in any echinoid.
The regeneration of globiferous pedicellariae in laboratory conditions takes 25 to 40 days. |
