Crayfish, which are crustaceans, differ from annelids in several key ways: firstly, crayfish have an exoskeleton made of chitin, while annelids possess a segmented body covered by a moist cuticle. Secondly, crayfish exhibit jointed appendages for movement, whereas annelids have soft, segmented bodies with bristles (setae) for locomotion. Finally, crayfish have a complex nervous system with a brain and specialized sense organs, while annelids have a simpler nervous system with a nerve cord and ganglia.
