Summary Introduction
To review:
The evolution of diversity in the basic body plan of the mollusks with some examples.
Introduction:
The animals belonging to phylum Mollusca are referred to as mollusks or mollusks, which is the largest marine phylum. These are highly diverse both morphologically and anatomically. However, every member of this phylum shares a basic body plan: mantle, foot, visceral mass. Some species may have a shell as their outermost body covering or present internally.

- Aquatic molluscs have a blood vascular system & metanephridia so they must also possess an unpartitioned coelom secretion kidneys terminal cells a partitioned coelom If a respiratory pigment such as hemoglobin or hemocyanin is not present in blood the blood would not carry carbon dioxide the blood would not carry oxygen the blood would have decreased oxygen carrying capacityarrow_forwardClass Gastropoda and Class Bivalvia independently evolved modifications to their body plan that allowed them to invade sandy and muddy habitats, burying their bodies under the surface and accessing the surface via siphons. For an example organism in each Class, (1) draw a diagram showing the morphological modifications and (2) write a description of how this organism had evolved from the hypothetical ancestral mollusk (HAM) body plan.arrow_forwardThe gastrovascular cavity of cnidarians has two openings, one serves as mouth and the other serves as anus.
