| Commercial fisheries for abalones exist in California, Mexico, Japan, and South Africa. |
| Furthermore, farming of crustaceans, mussels, clams and abalones is becoming increasingly important. |
| More than 7cm abalones must be prepared before cooking: the flesh must be separated from the shell and be slapped with a hammer in order to be softened. |
| From there it was only a stone's throw to the beach where the mussels and abalones clung so thickly to the rocks. |
| Brains of limpets and abalones are much simpler than brains of garden snails and slugs in histological differentiation. |
| In abalones, the eggs are enclosed by a vitelline envelope, and sperm must penetrate this envelope to fertilize the egg. |
