What are shellfish?

Shellfish are a diverse group of aquatic invertebrates that include mollusks and crustaceans. They are typically found in both saltwater and freshwater environments.

Another significant difference lies in their anatomy and habitats. Fish typically have fins and are more streamlined for swimming, while shellfish often possess hard shells and may live buried in sand or attached to rocks.
