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 (SWIMMERESTS) 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? i. How does the shape of a crab's abdomen differ from that of a crayfish? Observe the preserved crabs. J. The crayfish's intestine is relatively straight and short. Discuss how this relates to its diet. Can you infer anything from this observation?

What - Crayfish Dissection Worksheet structures are used for capturing prey and securing and eating food? How are the antennae, chelipeds, walking legs, and swimmerets related? You could observe the exoskeleton of the abdomen and tell the function of each. Is the crayfish most vulnerable to its enemies from the dorsal or ventral side? The crayfish usually molts, sheds its exoskeleton, twice a year. Why does the crayfish "hide" after molts? Name the appendages found on the head of the crayfish. Tell the function of each. Of the systems studied, which two are most unlike the related human system? Why?

Fiddler Crab Size One study of the male fiddler crab showed a connection between the weight of its claws and the animal's total body weight. For a crab weighing over 0.75 gram, the weight of its claws can be estimated by $$ f(x)=0.445 x^{1.25} $$ The input $x$ is the weight of the crab in grams, and the output $f(x)$ is the weight of the claws in grams. Predict the weight of the claws for a crab that weighs 2 grams. (Source: Huxley, J., Problems of Relative Growth, Methuen and Co.; Brown, D. and P.
