| Abstract: |
| C. onyx, originally distributed in California, was found in great quantities in Victoria Harbour, Hong Kong in 1982 and was identified according to the study of its morphology and the radula teeth. Lots of the individuals of the species lived in overlapping colony, with the female at the lower, and the male in the upper while the sex-transforming individual at the middle. They attached on the shells of Perna viridis in a high density of 715 ind./m2. Studies have been carried out on its population structure, individual size, age and sex composition and on reproductive biology, such as sex transformation, change of the length of penis and fecundity. |
