Fine microstructural detail can be preserved in calcium phosphate internal moulds and replacements of the shells of Cambrian molluscs
This finding is consistent with a mollusc
assemblage that was harvested frequently by 'range-limited' gatherers employing an encounter strategy.
The exploitation of shellfish is largely dependent on the capture and production of molluscs
During this time he corresponded with Keppel Barnard at the South African Museum, the then authority on South African marine molluscs
, and he also regularly visited Dolf van Bruggen who was at the time curator of the newly established Port Elizabeth Oceanarium.
1) also differed significantly among mollusc

Who is this M25-encased gastropod who can't tell his molluscs
from his lamellibranchs?
And Mr Farren was told the mollusc
could date from the Jurassic period.
Inasmuch as abiotic factors regulating freshwater mollusc
distribution are briefly mentioned in the last chapters, effects from environmental variables due to xenobiotics and human activities in general, were neglected.
lives embedded vertically in the bottom sediments (usually mud or muddy sand), and it is attached there by a net of byssus threads (Yonge 1953, Purchon & Purchon 1981).
If so, you may be disappointed that the approaches are entirely embedded in well-known traditional frameworks involving species' ecologies, ecological groups (nuanced, since 1991, by 'taxocenes') and mollusc
If the mollusc
is unable to get rid of the irritant, as part of its defence mechanism it produces conchiolin (an organic glue) and nacre (calcium carbonate crystallised in the form of aragonite).
Boring polychaetes frequently infest the shells of aquacultured mollusc
