  Mollusk - MSN Encarta
Mollusks are highly successful in terms of ecology and adaptation, with representatives in virtually all habitats, but they are most diverse in the sea.
Although few features are common to all mollusks, the animals are not readily mistaken for anything else, and all may be treated as variants on a common theme (not to be confused with a common ancestor).
In most mollusks a larval stage follows, in which the larvae swim about for a while and then settle on the bottom and mature; this stage is often modified or absent, however.

  Mollusk - Wikipedia, the free encyclopedia
The mollusks or molluscs are the large and diverse phylum Mollusca, which includes a variety of familiar creatures well-known for their decorative shells or as seafood.
Mollusks have a mantle, which is a fold of the outer skin lining the shell, and a muscular foot that is used for motion.
It is probable that the pre-Cambrian ancestor of the mollusks had calcium carbonate spicules embedded in its mantle and outer tissues, as is the case in some modern members.

The discovery of a complete fossil of the creature, an ammonite known as Diplomoceras maximum, is causing researchers to rethink their ideas on mollusk evolution.
Ammonites, which are related to the pearly nautilus, are among a group of invertebrates that date back more than 400 million years.
It may have looked ungainly, but it wouldn't have reached this size, or lasted as long, unless it was a good competitor," noted Zinsmeister.

 Fossil Groups - Mollusks
Mollusks are an amazingly diverse group of animals that live in a wide variety of environments.
Mollusks first appear in the fossil record about 545 million years ago in earliest Cambrian time, but the record of their origin and early evolution has not been discovered in the fossil record.
Mollusks have many of the properties of good index fossils: The hard shells of many mollusks means they are generally well-preserved, and they are often one of the few fossils found in certain environments.

 COA :: Mollusckque - Mollusk vs Mollusc
Malacologists and conchologists often wonder whether "mollusk" or "mollusc" is the correct or preferred spelling of the vernacular name for the phylum Mollusca.
The word "mollusk" probably was coined in response to growing acceptance of Cuvier's classification as set forth in his great work Regnè Animal (1817) which expanded the concept of "Mollusca" to include the bivalves and gastropods with the cephalopods.
"Mollusk" as used by Owen (1832) is clearly an Anglicization of "mollusque," whereas "mollusc" could be a noun form of "molluscous" or a vernacular singular for the plural "mollusca." The only source I examined that used "mollusque" as an English word was Isaac Lea (1828, Transactions of the American Philosophical Society III, p.

 University Week - No need for Tums: Penguins ingest mollusk shells to obtain calcium for thicker eggshells   (Site not responding. Last check: )
New research led by a University of Washington biologist shows that during the period when eggs are being laid, female penguins have significantly more mollusk shells, mainly clams and mussels, in their stomachs than males do.
But females lacking other sources of calcium ingest significantly more mollusk shells, which apparently supplements calcium taken from their bones for eggshell formation.
In the post-egg-laying period, few penguin stomachs contained mollusk shells and the findings were the same for male and female.
