Aplysia occurs in a variety of color patterns that
correlate with the seaweed upon which it is
feeding and living. Aplysia which is a gastropod
mollusc is one of the important candidates for marine
aquarium. It also has large ganglion nerve cells. This
neuron is very similar to those present in vertebrates,
making them good subjects for neurological research,
electrophysiological studies as well as studies on
conditioned responses. At present, we fully depend
on exploitation from the wild. In the present contet,
spawning of the aplysia Donabella rumphi kept in
captivity at Mandapam is reported
