No, it is a historical or obsolete grouping. Modern taxonomy recognises the subgroups (like Branchiopoda, Copepoda, etc.) as separate classes or subclasses within Crustacea.

Entomostracans are typically smaller, have a simpler body plan with fewer trunk segments and appendages, and include creatures like water fleas. Malacostracans are larger, more complex crustaceans like crabs, lobsters, and shrimp.

Yes, common garden pond entomostracans include Daphnia (water fleas) and Cyclops (copepods), which are visible as tiny moving specks in the water.

The prefix 'entomo-' comes from Greek 'entomon' meaning 'insect', referring to the segmented, 'cut-up' appearance of their bodies, which was seen as insect-like. Historically, arthropods (insects and crustaceans) were less distinctly classified.
