A crayfish has segments, which are sections of a body that are separated by a crease, so it might be determined as segmented because it has only two so it may be classified but it might not. Worms have many segments.
Crayfish are classified as arthropods, because of their characteristic segmented bodies, chitinous exoskeleton, and joint appendages.
Its tail or abdomen is segmented
Crayfishs have 2 body segments: cephalothorax and abdomen.
Because Its body structure has segments.
First of all, only the cephalothorax is inflexible. The tail is flexible, and if you look at it closely, it is clearly segmented. The cephalothorax is actually also segmented internally, but is masked by the shell, called a carapace.
Segmented worms are classified under the phylum Annelida. They are characterized by their body segmentation, which is divided into repetitive segments called metameres. Annelids include earthworms, leeches, and marine bristle worms.
The earwig is part of the class, Anthropoda. In order for an organism to be able to be classified as an anthropod, you must be have a segmented body
Soft bodied invertebrates classified into three groups based on body structure are flatworms, roundworms, and segmented worms. Flatworms have a flattened body, roundworms are cylindrical with a tapered ends, and segmented worms have distinct body segments.
Leeches are classified in phylum Annelida because they have segmented bodies with repeated body segments. They also have a closed circulatory system and belong to the subclass Hirudinea within the phylum Annelida.
Segmented worms are classified in the phylum Annelida, which includes earthworms, leeches, and marine polychaetes. These organisms are characterized by their segmented bodies, known as metamerism, which allows for greater flexibility and mobility.
