What is bigger molluces or crustations?
Mollusks and crustaceans are both diverse groups within the animal kingdom, but mollusks generally have a larger overall size range. Mollusks include species like squids and giant clams, which can grow quite large, while crustaceans, such as crabs and shrimp, tend to be smaller on average. However, the largest individual species of either group can vary significantly, so the comparison can depend on specific examples. Overall, mollusks tend to have a greater maximum size potential.
