What kind of digestive tract do pill bugs have? - AP Bio

Question

AP Bio help/questions on pill bugs and Class Malacostraca in general:

- Do Malacostracans have a complete or incomplete digestive tract?

- What external structures do they use to feed? (I assume its the maxillapeds)

-Do Malacostracans have internal or external fertilization?

- How is waste removed?

- What structure do they have to regulate salt balance? (I think its some type of gland and the hemolymph).

Answer 1

They have a complete digestive tract; they have micoorganisms living in their gut to aid in the digestion of cellulose.  I believe they have qa 2 chambered stomach and waste is expelled through their a**s.
