Question about crayfish

Postby HAiKUGiRL » Mon May 19, 2008 5:49 am

As you all know crayfish undergo a process known as molting. The crayfish's esophagus and intestine is lined with an exoskeleton of chitin; however the stomach is lined only with endoderm. Would this cause a problem during the organism's molting? If so, what?

Obvious if you know what molting is...
Living one day at a time;
Enjoying one moment at a time;
Accepting hardships as the pathway to peace;

I thought the exoskeleton covers the entire animal?
Generally speaking, the more people talk about "being saved," the further away they actually are from true salvation.

Same as insects, their breathing system of trachea is lined with exoskeleton, so that sheds as well. (Do you think that would itch?)

Hmmm... I can say with confidence I am not smart enough to know :)
