Does the phylum Arthropoda include freshwater crabs?

The phylum Arthropoda indeed includes freshwater crabs. This phylum is characterized by organisms that have exoskeletons, segmented bodies, and jointed appendages. Crustaceans, which are a specific sub-group within Arthropoda, include a wide variety of aquatic animals such as crabs, lobsters, and shrimp. Among these, there are both marine and freshwater species.

Freshwater crabs, such as those in the family Potamididae, thrive in freshwater environments and exemplify the diversity found within the crustacean group of the Arthropoda phylum. This indicates that the classification not only encompasses marine organisms but also extends to those that inhabit freshwater, confirming that yes, crabs, including freshwater varieties, belong to Arthropoda.
