1. The crab has ten pairs of jointed appendages, which include two large claws called chelipeds to capture food, and eight walking appendages. Notice the differences in the structure of these 8 pairs. - Compare the structures present in the first 3 pairs (modified as maxillipeds), and the last five pairs. - What do you think are the main functions of the last five pairs? - Crustaceans have biramous appendages. What structures are present only in the first pair? In the last pair? - What do you think are the functions of these structures?
