How do crustacea differ from other arthropod groups?
How do crustacea differ from other arthropod groups? only crustaceans have two pairs of antennae.

The hemolymph flows through the hemocoel and returns via venous sinuses rather than enclosed veins.
Which characteristic S separate the crustacea from the hexapoda?
Unlike that of the Hexapoda, the head and thorax of most crustaceans is fused to form a cephalothorax, which is covered by a plate called the carapace, thus producing a body structure of two tagma. Crustaceans have a chitinous exoskeleton that is shed by molting whenever the animal increases in size.
How are Hexapods related to crustaceans?
Studies based on morphology led to the Pancrustacea hypothesis, in which Crustacea and Hexapoda (insects and allies) are sister groups. More recent studies using DNA sequences suggest that Crustacea is paraphyletic, with the hexapods nested within a larger Pancrustacea clade.
