Adi S.
a) What are the functions of chelipeds, antennae, walking legs, mandibles, and swimmerets? b) Do crayfish have an open or closed circulatory system? How does this differ from the circulatory system of the earthworm? c) If crayfish and other crustaceans take up oxygen using gills, how do some of them manage to survive in the terrestrial environment? d) In terms of reproductive anatomy, how do crayfish compare with earthworms?
f. Is your crayfish male or female? How did you determine this? Be sure to look at one of the opposite sex. g. Describe 3 ways that crayfish can move. Which body parts are used for each method? Crayfish move underwater by fluttering small appendages (SWIMMERETS) Crayfish can use their legs to walk on land or on the floor of various bodies h. What is the function of the swimmerets? How does their structure make them suited for this purpose?
