The mollusks or molluscs are the large and diverse phylum Mollusca, which includes a variety of familiar animals well-known for their decorative shells or as seafood. These range from tiny snails, clams, and abalone to the octopus, cuttlefish and squid (which are considered the most intelligent invertebrates). There are some 112,000 species within this phylum.Feldkamp, Susan (2002). Modern Biology. United States: Holt, Rinehart, and Winston. pp. 725

The giant squid, which until recently had not been observed alive in its adult form, is the largest invertebrate; although it is possible that the Colossal Squid is even larger. The scientific study of mollusks is called malacology.

Anatomy


Mollusks are triploblastic protostomes. The principal body cavity is a blood-filled hemocoel. They have a true coelom (eucoelom); any coelomic cavities have been reduced to vestiges around the hearts, gonads, and metanephridia (kidney-like organs). The body is often divided into a head, with eyes or tentacles, a muscular foot and a visceral mass housing the organs.

Pectin power
Sun, 12 Oct 2008 00:00:00 -0400
(Norwich BioScience Institutes) Scientists from the UK's Institute of Food Research have found a new possible explanation for why people who eat more fruit and vegetables may gain protection against the spread of cancers.They have shown that a fragment released from pectin, found in all fruits and vegetables, binds to and is believed to inhibit galectin 3, a protein that plays a role in all stages of cancer progression.
