Cephalopods are active marine predators, and many molluscan features are modified to fulfill their niche. Explain how each molluscan feature is modified, compared to gastropod and bivalve body plans.
1) Molluscan foot
2) Excurrent Siphon
3) Shell
4) Sensory organs and brain
Brachiopods superficially resemble bivalve molluscs, such as clams. How would you explain the differences in symmetry and internal structure to a layperson?
How does the lifestyle of a gastropod differ from that of a cephalopod?Identify adaptations that have evolved in each for its particular lifestyle.
